    A pragmatic approach to define anthropometric boundary manikins for multiple populations2012Ingår i: NES2012 Proceedings, Saltsjöbaden, Sweden, August 19-22, 2012: Ergonomics for sustainability and growth / [ed] Ann-Beth Antonsson & Göran M. Hägg, Stockholm: KTH Royal Institute of Technology, 2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper addresses the call for methods that can assist designers to consider anthropometric diversity when designing products or workstations, and hence formulate more sustainable design solutions. A basic method for the definition of boundary manikins for bivariate design problems and combined populations is described, exemplified and evaluated. The method can be used for defining virtual test groups when using digital human modelling tools for evaluating anthropometry related aspects of human-product interfaces at early design phases. It can also be used to indentify persons with certain anthropometry to build up test groups for performing physical tests.

    A basic step towards increased accommodation level accuracy when using DHM tools2011Ingår i: Proceedings of DHM, First International Symposium on Digital Human Modeling, Université Claude Bernard Lyon , 2011, s. 1-6Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper addresses the need to consider anthropometric diversity in design and suggests a basic approach for the simultaneous consideration of variance in two key dimensions. This as a basic step from the common, but in many cases poor, approach to use univariate percentile data in design. The bivariate method described can be applied when utilising DHM tools for design in that key dimension values for extreme but likely anthropometric measurement combinations are calculated and entered as input data when representative manikins are defined. The mathematical procedure is described and the outcome of the method is compared to a typical percentile based approach, indicating more accurate accommodation levels being reached by the proposed method. The method is to be seen as a simple method to be used for basic design problems where variance in few anthropometric dimensions are to be considered simultaneously, and not as an alternative for more advanced multivariate methods. The paper takes a pragmatic standpoint, directing its message towards practitioners using DHM tools for design purposes.

    Accommodation levels for ellipsoid versus cuboid defined boundary cases2015Ingår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, s. 3702-3708Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The boundary case method is established for the representation and consideration of anthropometric diversity in design tasks with certain characteristics. Sometime boundary cases are defined separately for two distributions, e.g. for females and males, which may lead to a situation where some boundary cases will be redundant in that they are located within the joint distribution rather than on the joint boundary. This paper describes and illustrates a method for automatic identification of redundant boundary cases that are located within two three-dimensional overlapping distributions.

    Practitioner Summary: The paper describes a pragmatic way to focus the design work on users with specific limiting body measurement combinations that can be used to obtain design data or be used to describe appropriate test persons or digital human models for design problems where the boundary case method is suitable.

    Accommodation levels for ellipsoid versus cuboid defined boundary cases2015Ingår i: Proceedings of the 6th International Conference on Applied Human Factors and Ergonomics (AHFE 2015), AHFE , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The definition and use of boundary cases is a common approach when aiming to anthropometrically accommodate a desired percentage of the targeted population by a design. The cases are defined based on anthropometric data that represents the targeted population. Approaches that define cases based on the variation within just one body measurement are poor for most design problems in representing anthropometric diversity. Hence, the consideration of variation within several body measurements is preferred. However, an approach that is based on performing several separate studies of the variation within a number of measurements leads to undesired reduction of accommodation due to the lack of consideration of the effects of correlations between measurements. This paper compares theoretical accommodation levels when using an ellipsoid versus a cuboid based approach for defining boundary cases to represent anthropometric variation within three body measurements. The ellipsoid approach considers correlations between body measurements whereas the cuboid approach does not consider correlations between body measurements. The paper suggests the application of the ellipsoid method for defining boundary cases for better reaching desired accommodation levels in boundary case based design problems. These cases can be used to define computer manikins when using digital human modelling tools. The method is also applicable when wishing to select extreme but representative real people to be involved in physical fitting trials.

    Concept of Formalized Test Procedure for Proactive Assessment of Ergonomic Value by Digital Human Modelling Tools in Lean Product Development2018Ingår i: Advances in Human Factors in Simulation and Modeling: Proceedings of the AHFE 2017 International Conference on Human Factors in Simulation and Modeling / [ed] Cassenti, Daniel N., Cham, Switzerland: Springer, 2018, Vol. 591, s. 425-436Konferensbidrag (Refereegranskat)
    Abstract [en]

    A concept of a formalized test procedure for proactive assessment of ergonomic value by digital human modelling (DHM) tools in lean product development (LPD) is proposed and described. The objective of the formalized procedure is to integrate the utilization of DHM tools in LPD and to support the delivery of ergonomic value and reduce waste in product and production development processes. A design process model is illustrated and described, and examples are given of how to specify and work with ergonomic value in the process.

    Creating and shaping the DHM tool IMMA for ergonomic product and production design2016Ingår i: International Journal of the Digital Human, ISSN 2046-3375, Vol. 1, nr 2, s. 132-152Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The history, status and outlook of the research and development actions associated with the creation of the digital human modelling tool intelligently moving manikins (IMMA) are described. The underlying fundamental concepts are described and research and development results so far are illustrated or referred to. Two case studies illustrating use of IMMA on industry-based problems are described. The paper also covers reflections on conceptions for prospective DHM tool developments from a general perspective, relating to areas of ergonomics and design methodology, as well as describing some of the plans for further developments and applications of the IMMA tool. These may be of assistance when identifying challenges for future research and development of DHM tools that are used in product and production design processes in industry.

    Increasing Functionality of DHM Software by Industry Specific Program Features2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper illustrates how Digital Human Modeling (DHM) tool functionality can be increased through the development of industry specific features. The features are based on a design tool, the Mobility Gallery, established by the cooperating health care company. Each resident in the Mobility Gallery has different levels of functional mobility and is described with different personal characteristics as well as background details. The integration of the resident descriptions in a commercial DHM tool is presented and discussed. The rationale for this approach is that the synthesis of DHM tool functionality and the Mobility Gallery descriptions will render a DHM tool with features offering augmented applicability for product design in a health care setting.

    DHM Based Test Procedure Concept for Proactive Ergonomics Assessments in the Vehicle Interior Design Process2018Ingår i: Proceedings of the 20th Congress of the International Ergonomics Association (IEA 2018): Volume V: Human Simulation and Virtual Environments / [ed] Sebastiano BagnaraRiccardo TartagliaSara AlbolinoThomas AlexanderYushi Fujita, Cham, Switzerland: Springer, 2018, Vol. 822, s. 314-323Konferensbidrag (Refereegranskat)
    Abstract [en]

    The development of a digital human modelling (DHM) based test procedure concept for the assessment of physical ergonomics conditions in virtual phases of the vehicle interior design process is illustrated and discussed. The objective of the test procedure is to be a valuable tool for ergonomic evaluations and decision support along the design process, so that ergonomic issues can be dealt with in an efficient, objective and proactive manner. The test procedure is devised to support companies in having stable and objective processes, in accordance with lean product development (LPD) philosophies. The overall structure and fundamental functionality of the test procedure concept is explained by a simplified use case, utilizing the DHM tool IPS IMMA to: define manikin families and manikin tasks; predict manikin motions; and visualize simulations and ergonomics evaluation outcomes.

    Transitlager som en strategi i ett globalt distributionssystem2010Ingår i: Bättre Produktivitet, ISSN 1402-1145, nr 5, s. 12-16Artikel i tidskrift (Övrig (populärvetenskap, debatt, mm))
    Abstract [sv]

    Distributionen har kommit att bli en nyckelfaktor i dagens logistiksystem i och med att företag önskar uppnå skalfördelar i sin produktion genom fokuserade fabriker samtidigt som dagens kunder kräver alltmer kundanpassade produkter och leveranser till kortare ledtider. Syftet med denna studie är att undersöka om transitlagerstrategin, som ett komplement till den centraliserade och den decentraliserade distributionsstrategin, kan erbjuda företag konkurrensfördelar. Transitlagerstrategin kan ge stora konkurrensfördelar genom att den erbjuder relativt korta leveranstider utan att produkterna behöver lagerhållas lokalt, vilket ger lägre lagerhållningskostnader och en lägre kapitalbindning. För att lyckas med strategin krävs en god planering, kundsamarbete, marknadskännedom och ett informationssystem som klarar av att stödja strategin.

    Abstract [en]

    Reuse of virtual engineering models and simulations improves engineering efficiency. Reuse requires preserving the information provenance. This paper suggests a framework based on the 7W data provenance model to be part of simulation data management implemented in product lifecycle management systems. The resulting provenance framework is based on a case study in which a product was re-engineered using finite element analysis.

    Proposal of an Intuitive Interface Structure for Ergonomics Evaluation Software2018Ingår i: Proceedings of the 20th Congress of the International Ergonomics Association (IEA 2018): Volume VIII: Ergonomics and Human Factors in Manufacturing, Agriculture, Building and Construction, Sustainable Development and Mining / [ed] Sebastiano Bagnara, Riccardo Tartaglia, Sara Albolino, Thomas Alexander, Yushi Fujita, Cham: Springer, 2018, Vol. 825, s. 289-300Konferensbidrag (Refereegranskat)
    Abstract [en]

    Nowadays, different technologies and software for ergonomics evaluations are gaining greater relevance in the field of ergonomics and production development. The tools allow users such as ergonomists and engineers to perform assessments of ergonomic conditions of work, both related to work simulated in digital human modelling (DHM) tools or based on recordings of work performed by real operators. Regardless of approach, there are many dimensions of data that needs to be processed and presented to the users.

    The users may have a range of different expectations and purposes from reading the data. Examples of situations are to: judge and compare different design solutions; analyse data in relation to anthropometric differences among subjects; investigate different body regions; assess data based on different time perspectives; and to perform assessments according to different types of ergonomics evaluation methods. The range of different expectations and purposes from reading the data increases the complexity of creating an interface that considers all the necessary tools and functions that the users require, while at the same time offer high usability.

    This paper focuses on the structural design of a flexible and intuitive interface for an ergonomics evaluation software that possesses the required tools and functions to analyse work situations from different perspectives, where the data input can be either from DHM tools or from real operators while performing work.

    Application of Multi-objective Optimization on Ergonomics in Production: A Case Study2020Ingår i: Advances in Additive Manufacturing, Modeling Systems and 3D Prototyping: Proceedings of the AHFE 2019 International Conference on Additive Manufacturing, Modeling Systems and 3D Prototyping, July 24-28, 2019, Washington D.C., USA / [ed] Massimo Di Nicolantonio, Emilio Rossi, Thomas Alexander, Springer, 2020, s. 584-594Konferensbidrag (Refereegranskat)
    Abstract [en]

    Taking a holistic perspective is central in production development, aiming to optimize ergonomics and overall production system performance. Hence, there is a need for tools and methods that can support production companies to identify the production system alternatives that are optimal regarding both ergonomics and production efficiency. The paper presents a devised case study where multi-objective optimization is applied, as a step to towards the development of such an optimization tool. The overall objective in the case study is to find the best order in which an operator performs manual tasks during a workday, considering ergonomics and production system efficiency simultaneously. More specifically, reducing the risk of injury from lifting tasks and improving the throughput are selected as the two optimization objectives. An optimization tool is developed, which communicates with a digital human modelling tool to simulate work tasks and assess ergonomics.

    We embed neighborhood geometries of graphs on surfaces as point-circle configurations. We give examples coming from regular maps on surfaces with a maximum number of automorphisms for their genus, and survey geometric realization of pentagonal geometries coming from Moore graphs. An infinite family of point-circle v4 configurations on p-gonal surfaces with two p-gonal morphisms is given. The image of these configurations on the sphere under the two p-gonal morphisms is also described.

    Supply Chain Planning in Automotive Sector: Swedish Case Study2010Ingår i: Proceedings of the PLAN Research Conference / [ed] Ujvari, Sandor, Logistikföreningen PLAN , 2010, s. 53-72Konferensbidrag (Refereegranskat)
    Abstract [en]

    This research aims to enhance current knowledge of supply chain planning (SCP) by analyzing the importance of collaboration, information exchange and a supporting information system in its successful execution. The issues are examined through a case study from international manufacturing company, Volvo Powertrain, which operates in automotive industry through its worldwide manufacturing network. This research reveals that collaboration is a complex and important issue of SCP, and occurs simultaneously in vertical and horizontal dimensions. It is important to select strategic partners and to develop structured work processes and routines. The main objective of collaboration is to determine common goals and objectives and to facilitate the exchange of information and these together drives the performance of a supply chain. A sufficient information system supporting the SCP is vital to facilitate collaboration, and information exchange between the different supply chain participants. However, currently in Volvo Powertrain quite many phases of SCP are completed without appropriate and integrated information systems and the process itself contains several manual phases. This study is explorative in nature and more empirical data, from similar and other research settings, is needed to further validate the findings. However, its empirical findings strengthen research discipline knowhow of SCP in global manufacturing companies. This research provides insight to managers and practitioners on how to coordinate operations planning and control (OPC) across organizations within the supply chain to enhance efficiency and effectiveness. The SCP procedures described in this research work also are valuable for Volvo Powertrain and other industrial actors to further develop processes to respond on competitive pressure. This research work empirically demonstrates, as very few before have done so, how OPC can be coordinated across the supply chain.

    A Semantic Framework With Humans in the Loop for Vulnerability-Assessment in Cyber-Physical Production Systems2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    Criticalmanufacturingprocessesinsmartnetworkedsystems such as Cyber-Physical Production Systems (CPPSs) typically require guaranteed quality-of-service performances, which is supported by cyber- security management. Currently, most existing vulnerability-assessment techniques mostly rely on only the security department due to limited communication between di↵erent working groups. This poses a limitation to the security management of CPPSs, as malicious operations may use new exploits that occur between successive analysis milestones or across departmental managerial boundaries. Thus, it is important to study and analyse CPPS networks’ security, in terms of vulnerability analysis that accounts for humans in the production process loop, to prevent potential threats to infiltrate through cross-layer gaps and to reduce the magnitude of their impact. We propose a semantic framework that supports the col- laboration between di↵erent actors in the production process, to improve situation awareness for cyberthreats prevention. Stakeholders with dif- ferent expertise are contributing to vulnerability assessment, which can be further combined with attack-scenario analysis to provide more prac- tical analysis. In doing so, we show through a case study evaluation how our proposed framework leverages crucial relationships between vulner- abilities, threats and attacks, in order to narrow further the risk-window induced by discoverable vulnerabilities.

    Adaptive tool-path generation of rapid prototyping for complex product models2011Ingår i: Journal of manufacturing systems, ISSN 0278-6125, E-ISSN 1878-6642, Vol. 30, nr 3, s. 154-164Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Rapid prototyping (RP) provides an effective method for model verification and product development collaboration. A challenging research issue in RP is how to shorten the build time and improve the surface accuracy especially for complex product models. In this paper, systematic adaptive algorithms and strategies have been developed to address the challenge. A slicing algorithm has been first developed for directly slicing a Computer-Aided Design (CAD) model as a number of RP layers. Closed Non-Uniform Rational B-Spline (NURBS) curves have been introduced to represent the contours of the layers to maintain the surface accuracy of the CAD model. Based on it, a mixed and adaptive tool-path generation algorithm, which is aimed to optimize both the surface quality and fabrication efficiency in RP, has been then developed. The algorithm can generate contour tool-paths for the boundary of each RP sliced layer to reduce the surface errors of the model, and zigzag tool-paths for the internal area of the layer to speed up fabrication. In addition, based on developed build time analysis mathematical models, adaptive strategies have been devised to generate variable speeds for contour tool-paths to address the geometric characteristics in each layer to reduce build time, and to identify the best slope degree of zigzag tool-paths to further minimize the build time. In the end, case studies of complex product models have been used to validate and showcase the performance of the developed algorithms in terms of processing effectiveness and surface accuracy.

    From standard 3PL provider to service developer: a case study from the Swedish furniture industry2009Ingår i: World Review of Intermodal Transportation Research (WRITR), ISSN 1749-4729, E-ISSN 1749-4737, Vol. 2, nr 4, s. 376-390Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The strong competition between companies has resulted in an increased outsourcing of activities that are not considered core activities. This has created an emerging business opportunity in logistics, attracting several new actors and companies to enter the market and fill the demand for new services. These actors represent several types of providers who are often called Third-Party Logistics (3PL) providers. The purpose of this study is to investigate the environment of a 3PL provider that also develops services. The focus is particularly on how the provider has evolved and identifying the key issues on how to be successful in the 3PL industry. The primary research strategy is a descriptive embedded single case study. The findings reveal that the case company has evolved from being a standard 3PL provider to a service developer, since it, in addition to traditional services, nowadays also provides more value-added services. These services involve a set of more standardised activities that can be combined according to each customer's wishes and requirements. The findings also reveal that the main requirements to be a successful service developer are a clear customer understanding and focus, value-added and customised services and reliable deliveries (both in terms of time and a low percentage of damaged goods), as well as the utilisation of Information and Communications Technology (ICT).

    Electronic structure of (Ga,Mn)As revisited2017Ingår i: New Journal of Physics, ISSN 1367-2630, E-ISSN 1367-2630, Vol. 19, nr 2, s. 1-8, artikel-id 023006Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The detailed nature of electronic states mediating ferromagnetic coupling in dilute magnetic semiconductors, specifically (Ga,Mn)As, has been an issue of long debate. Two confronting models have been discussed emphasizing host band vs. impurity band carriers. Using angle resolved photoemission we show that the electronic structure of the (Ga,Mn)As system is significantly modified from that of GaAs throughout the valence band. Close to the Fermi energy, the presence of Mn induces a strong mixing of the bulk bands of GaAs, which results in the appearance of a highly dispersive band in the gap region of GaAs.

    For Mn concentrations above 1% the band reaches the Fermi level, and can thus host the delocalized holes needed for ferromagnetic coupling. Overall, our data provide a firm evidence of delocalized carriers belonging to the modified host valence band.

    An interactive decision support system using simulation-based optimization and knowledge extraction2018Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The use of simulation to improve existing manufacturing systems is not new, but simulation can also be used increase the understanding of production systems that have not yet been built. The power of simulation models can be further enhanced by using simulation-based optimization, in which an optimization algorithm tries to find optimal solutions, given certain objectives. However, extracting knowledge from the data resulting from simulation experiments and simulation-based optimization is a complex task. Therefore, tools are needed to assist users in this task. These tools can be visual, like diagrams, or can be generated by data mining. The process of running a study using simulation-based optimization to extract knowledge is a manual task that can in part be automated using existing tools, but to the author’s knowledge there is no software that implements the complete process. This work aims to develop a novel decision support system to support the generic decision process when using simulation and simulation-based optimization. The first step in setting up such a system is to understand how industry currently uses simulation and simulation-based optimization in manufacturing operations. Thus a questionnaire was distributed to manufacturing companies and organizations. The results showed that these techniques are being used, but that companies want more help with the analysis of the results as well as an automated guide in the decision process. This work proposes a system that supports a generic decision process by providing a tool with which a user can define a workflow in their organization, using simulation-based optimization as one component. The decision support system then provides tools for extracting knowledge in the form of diagrams and performs data mining for automated analysis. Data mining is part of the workflow as a tool for extracting knowledge after an optimization, as well as a tool for guiding optimization to suit the users’ preferences. The decision support system also provides for visualization of simulation models and optimization results using augmented reality. A head-mounted display helps users to see the results and model behaviors in 3D. This technology also makes it possible for users to collaborate, both in the same location and remotely. These visual and automatic analysis tools are shown to be effective in several application studies of real-world production scenarios in which data mining has been used to extract important knowledge that would be hard to obtain manually. Together with the automated workflow and efficient visualization of simulation and optimization results in augmented reality, the decision support system is believed to be an effective tool for extracting knowledge for general production systems design and analysis.

    Abstract [en]

    Although the idea of using Augmented Reality and simulation within manufacturing is not a new one, the improvement of hardware enhances the emergence of new areas. For manufacturing organizations, simulation is an important tool used to analyze and understand their manufacturing systems; however, simulation models can be complex. Nonetheless, using Augmented Reality to display the simulation results and analysis can increase the understanding of the model and the modeled system. This paper introduces a decision support system, IDSS-AR, which uses simulation and Augmented Reality to show a simulation model in 3D. The decision support system uses Microsoft HoloLens, which is a head-worn hardware for Augmented Reality. A prototype of IDSS-AR has been evaluated with a simulation model depicting a real manufacturing system on which a bottleneck detection method has been applied. The bottleneck information is shown on the simulation model, increasing the possibility of realizing interactions between the bottlenecks.

    An Interactive, Cloud-Based Simulation Optimization System for Knowledge Discovery and Decision Support In Manufacturing2014Ingår i: Proceedings of the sixth Swedish Production Symposium, 2014, 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Designing or improving a manufacturing system involves a series of complex decisions over time to satisfy the strategic objectives of the company. To select the optimal parameters of the system entities so as to achieve the desired overall performance of the system is a very complex task that has been proven to be difficult, even for a seasoned decision maker. One of the major barriers for more efficient decision making in manufacturing is that whilst there is in principle abundant data from various levels of the factory, these data need to be organized and transferred into knowledge suitable for decision-making support. The integration of decision-making support and knowledge management has been identified to be more and more important in both scientific research and from industrial companies. The concept of deciphering knowledge from multi-objective optimization was first proposed by Deb with the term innovization (innovation via optimization). By integrating the concept of innovization with simulation, a new set of powerful tools for manufacturing systems analysis, in order to support optimal decision making in design and improvement activities, is emerged. This method is so-called Simulation-based Innovization (SBI), which has been proven to produce promising results in our previous application studies. Nevertheless, to promote the wider use of such a new method requires the development of an integrated software toolset. The goal of this paper is therefore to outline a Cloud-computing based system architecture for implementing such a SBI-based Interactive Decision Support System.

    Abstract [en]

    This paper describes a decision support system (DSS) built on knowledge extraction using simulation-based optimization and data mining. The paper starts with a requirements analysis based on a survey conducted with a number of industrial companies about their practices of using simulations for decision support.Based upon the analysis, a new, interactive DSS that can fulfill the industrial requirements, is proposed.The design of the cloud-based system architecture of the DSS is then described. To show the functionality and potential of the proposed DSS, an application study has been performed for the optimal design of a hypothetical but realistic flexible production cell. How important knowledge with respect to different preferences of the decision maker can be generated as rules, using the new Flexible Pattern Mining algorithm provided in the DSS, will be revealed by the results of this application study.

    Interactive and Intelligent Decision Support in Manufacturing using Simulation Based Innovization and Cloud Computing2014Ingår i: Industrial Simulation Conference, Skövde, June 11-13, 2014, 2014, s. 69-74Konferensbidrag (Refereegranskat)
    Abstract [en]

    Simulation-based innovization is a method for extracting knowledge from a simulation model and optimization. This method can help decision makers to make high-quality decisions for their manufacturing systems so as to enhance the competitiveness of companies. Nevertheless, the simulation-based innovization process can be computationally costly and having these resources in-house can be expensive. By running the process in a cloud environment instead, the company only pays for the resources they are using. This paper proposes the concept of a cloud-based computing platform that can run the simulation-based innovization process and discuss its possibilities and challenges.

    A hybrid approach for dynamic routing planning in an automated assembly shop2010Ingår i: Robotics and Computer-Integrated Manufacturing, ISSN 0736-5845, E-ISSN 1879-2537, Vol. 26, nr 6, s. 768-777Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Highly turbulent environment of dynamic job-shop operations affects shop floor layout as well as manufacturing operations. Due to the dynamic nature of layout changes, essential requirements such as adaptability and responsiveness to the changes need to be considered in addition to the cost issues of material handling and machine relocation when reconfiguring a shop floor’s layout. Here, based on the source of uncertainty, the shop floor layout problem is split into two sub-problems and dealt with by two modules: re-layout and find-route. GA is used where changes cause the entire shop re-layout, while function blocks are utilised to find the best sequence of robots for the new conditions within the existing layout. This paper reports the latest development to the authors’ previous work.

    Abstract [en]

    Nowadays, product-mix in small batches contributes to shop floor uncertainties, whereas distributed resources are handled collaboratively during assembly planning. There is a growing need to develop methods that can increase adaptability and flexibility in dynamic and collaborative job-shop assembly floors. Based on our previous work on an assembly planning framework using Function Blocks (FBs), a novel approach to assembly planning and control is developed, which enables adaptive decision making besides effective plan execution. Following our previous work, this paper reports the latest development of design and simulation of an FB communication network in Matlab-Simulink environment, and validates the methodology through an example.

    Increasing Adaptability of Assembly Planning and Control with Embedded Decision-Making Capability2009Ingår i: Transactions of the North American Manufacturing Research Institution of SME, ISSN 1047-3025, Vol. 37, s. 533-540Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In our previous work, a framework and a new methodology for adaptive assembly process planning using function block (FB) concept was introduced. Function blocks are adopted to deal with dynamic job shop assembly floors, where product-mix often in small batches contributes to manufacturing uncertainty, making adaptability an important item on a company's wish list. FB-enabled assembly planning and control enables not only adaptive decision making but effective plan execution. Following our previous work, this paper reports the development of simulating a function block communication network in the Matlab Simulink environment and demonstrating the implementation of the methodology through an example.

    Two-Stage Hybrid Adaptive Assembly Layout Planning2010Ingår i: Transactions of the North American Manufacturing Research Institution of SME, ISSN 1047-3025, Vol. 38, s. 735-742Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The manufacturing environment today is highly turbulent. Hence, the potential to alter factory layout has transformed the layout problem from considering long-term material handling costs to considering essential requirements, such as adaptability and proactive responsiveness to dynamic changes. This is beyond the costs of material handling and machine relocation when reconfiguring the layout. As continuation of the authors’ previous work, this paper proposes to incorporate function block methodology in dealing with the layout issues in the frequently changing environment of job-shop assembly operations so as to increase the autonomy and adaptability of the assembly operations against changes.

    Ergonomic Risk Assessment of a Manikin’s Wrist Movements - a Test Study in Manual Assembly2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    Use of digital human modeling (DHM) tools enables early assessment of ergonomic risks in the production development process. This early risk assessment can indicate needs for preventive actions in order to decrease risks for work-related musculoskeletal disorders. A method for the assessment of physical workload has been developed, for the analysis of wrist joint data produced by a DHM tool. The method is tested in a simulation model of an actual manual assembly station in industry where it is assumed that physical workload problems exist. The results show that the method can be successfully applied on an industrial case. In addition, presumptive risks and possible diagnoses are predicted based on the similarity of the simulated task’s motions with motions from other known work class profiles stored in a database based on epidemiological research.

    Managing Interruptions in Manufacturing: Towards a Theoretical Framework for Interruptions in Manufacturing Assembly2016Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The effect of interruptions from ICT systems on assembly workers in manufacturing is examined in this thesis, as is how the risks of errors, increases in assembly time, increased cognitive load and resultant stress can be mitigated, as well as ensuring that important new information is acted upon. To these ends, a literature study was conducted, followed by two studies using an experimental approach in an environment that simulated a manufacturing assembly situation, and used tasks designed to be representative of manufacturing assembly tasks. The results of the literature study and the two studies are presented in four appended papers. The body of the thesis itself introduces similar material, and takes a step towards the creation of a theoretical framework that supports analysing the tasks and environments in question from a embodied and situated (DEEDS or 4E) viewpoint on cognition. This theoretical framework uses graphical representations similar to storyboards to support the analyst in maintaining an embodied and situated viewpoint during analyses of active tasks that require an examination of the interplay between brain, body, and environment. Supporting an embodied viewpoint during analysis has the purpose of facilitating the design of interruption coordination systems that take into account the embodied and situated nature of the tasks faced in manual tasks such as assembly in manufacturing.

    Situating interruptions in manufacturing assembly2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Denna avhandling undersöker hur olika former av att bli avbruten från sin nuvarande uppgift av antingen andra personer eller av datorbaserade informationssystem påverkar monteringspersonal inom tillverkningsindustrin. Avhandlingen presenterar sedan olika strategier för att reducera de negativa effekterna av avbrotten. Datorbaserade informationssystem (IT-system) används i allt större omfattning inom industrin för att effektivisera produktionen och undvika arbetskrävande manuell uppdatering av information. Notifieringar behövs eftersom montören kan ha behov av ny information som har blivit tillgänglig och i vissa fall måste arbetsuppgifter ändras omedelbart baserat på den nya informationen. Detta kräver olika former av avbrott och existerande forskning visar att det att bli avbruten kan leda till ökat antal fel, längre tid för att utföra den huvudsakliga uppgiften och ökad stress.

    Avbrott har studerats tidigare för att testa när det är lämpligt att avbryta någon och hur. Dock har den tidigare forskningen främst genomförts i situationer som inte liknar vanliga arbetsuppgifter. Forskning finns där avbrott har observerats inom sjukvården, men det kan inte fastställas att samma teorier fungerar för att stödja montörer inom industrin.

    En existerande och etablerad taxonomi för avbrott identifierades att vara av stor relevans för detta arbete, men eftersom taxonomin enbart hade använts på uppgifter av mer artificiell karaktär behövde den testas under mer verklighetsliknande förhållanden inom tillverkningsindustrin. Denna avhandling innehåller resultat från två experiment som utfördes för att undersöka om taxonomin även fungerar vid manuellt monteringsarbete inom tillverkningsindustrin. Eftersom att experimenten innebar en stor risk för ett ökat antal fel under monteringsarbetet valdes istället simulera en monteringslina, som innebär att en hyfsat verklighetstrogen monteringslina byggdes enbart för att bedriva experiment.

    Resultaten visar att det finns skillnader mellan att använda uppgifter av artificiell karaktär i en labbmiljö och att använda mer autentiska uppgifter som efterliknar faktiskt monteringsarbete. En viktig skillnad som identifierades fick benämningen negotiation element, och visar hur det nästan alltid går att välja (till någon grad) när avbrott åtgärdas. Identifieringen av lämpliga avbrottstillfällen visade sig också vara svårare än vad som antogs på förhand, som ledde till det andra experimentet där detta studerades i mer detalj. Andra experimentet visade att en utav de förvalda avbrottstillfällena inte alls fungerade lika bra som förväntat. En observationsstudie utfördes också i en fullt naturlig tillverkningsmiljö för att kategorisera hur störningar hanteras av montörer i denna miljön. Denna studie visade att klassiska avbrott där montören byter ifrån sin uppgift till en annan uppgift var väldigt sällsynta, och detta sågs vara på grund av att uppgifterna är designade för att undvika avbrott, samt att montörerna är erfarna och har träning för att undvika avbrott. Resultaten från dessa tre studier användes för att bygga ihop olika teorier för att skapa ett teoretiskt ramverk som introduceras i avhandlingen. Detta ramverk använder grafiska metoder för att analysera och mer intuitivt kunna förstå hur avbrott inverkar på manuella monteringsuppgifter.

    Showing uncertainty in aircraft cockpits using icons2015Ingår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, s. 2905-2912Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper examines an icon set designed for displaying uncertainty surrounding threat levels of an approaching object in anaircraft cockpit. This is done through an experiment that compares an icon set designed for this experiment with two icon setsfrom existing research that were tested in static laboratory conditions. The experiment used a flight simulator to simulate realisticflight conditions. The results showed that the icon set designed for this experiment was easier to read. Guidelines for the designof icons for displaying uncertainty are presented based on the results of the experiment.

    Classification of Collaboration Levels for Human-Robot Cooperation in Manufacturing2018Ingår i: Advances in Manufacturing Technology XXXII: Proceedings of the 16th International Conference on Manufacturing Research, incorporating the 33rd National Conference on Manufacturing Research, September 11–13, 2018,  University of Skövde, Sweden / [ed] Peter Thorvald, Keith Case, Amsterdam: IOS Press, 2018, s. 151-156Konferensbidrag (Refereegranskat)
    Abstract [en]

    Industry 4.0 aims to support the factory of the future, which involves increased amounts of information systems and new ways of using automation. One new usage is collaboration between human and industrial robot in manufacturing, with both partners sharing work on a single task. Supporting human-robot collaboration (HRC) requires understanding the requirements of HRC as well as the differences to existing approaches where the goal is more automation, such as in the case of self-driving cars. We propose a framework that we call levels of collaboration to support this, and posit that this framework supports a mental model conducive to the design of lines incorporating HRC.

    Foundation for a classification of collaboration levels for human-robot cooperation in manufacturing2019Ingår i: Production & Manufacturing Research, ISSN 2169-3277, Vol. 7, nr 1, s. 448-471Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Industry 4.0 aims to support the factory of the future, involving increased use of information systems and new ways of using automation, such as collaboration where a robot and a human share work on a single task. We propose a classification of collaboration levels for Human-Robot collaboration (HRC) in manufacturing that we call levels of collaboration (LoC), formed to provide a conceptual model conducive to the design of assembly lines incorporating HRC. This paper aims to provide a more theoretical foundation for such a tool based on relevant theories from cognitive science and other perspectives of human-technology interaction, strengthening the validity and scientific rigour of the envisioned LoC tool. The main contributions consist of a theoretical grounding to motivate the transition from automation to collaboration, which are intended to facilitate expanding the LoC classification to support HRC, as well as an initial visualization of the LoC approach. Future work includes fully defining the LoC classification as well as operationalizing functionally different cooperation types. We conclude that collaboration is a means to an end, so collaboration is not entered for its own sake, and that collaboration differs fundamentally from more commonly used views where automation is the focus.

    Mind the body: How embodied cognition matters in manufacturing2015Ingår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, s. 5184-5191Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Embodied cognition can provide human factors and applied ergonomics practitioners with better embodied cognition design principles. This paper investigates and analyzes observational video-recorded data from an experiment that simulated a manufacturing environment. The operator was interrupted during a primary assembly task via a handheld computing device which delivered different classes of notifications. The focus is on the embodied aspect of notifications in an active environment, and why one class of notifications called mediated notifications failed at a specific point previously thought to be suitable. Guidelines for analyzing tasks from an embodied cognition perspective that complements and expands traditional human factors and applied ergonomics approaches were developed and are included.

    Missing mediated interruptions in manual assembly: Critical aspects of breakpoint selection2017Ingår i: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 61, s. 90-101Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The factory of the future aims to make manufacturing more effective and easily customisable, using advanced sensors and communications to support information management. In this paper, we examine how breakpoint selection during interruption management can fail, even when using recommendations for interruption management from existing research. We present an experiment based on prior work where mediated interruptions (i.e. smart interruptions that should interrupt at opportune moments) were missed by participants when sent at one of two pre-defined breakpoints. These breakpoints were selected based on existing research to minimise the cost of interruption, which can involve longer times to complete tasks as well as making errors on tasks. Missing mediated interruptions in this way was unexpected, and the prior study was not configured to measure this effect, which has led to the experiment detailed here. We strive to explore whether there is a risk of missing notifications when mediated interruptions are used, and how this is affected by breakpoint selection. This was investigated through an experiment that uses tasks and environments that simulate a manufacturing assembly facility.

    The results indicate that the effect exists, i.e. that participants miss significantly more notifications when interrupted at fine breakpoints than when interrupted at coarse breakpoints. An embodied cognition perspective was used for analysis of the tasks to understand the cause of the effect. This analysis shows that an overlap between “action” and “anticipation of action” can account for why participants miss notifications at fine breakpoints. Based on these findings, recommendations were developed for designing interruption systems that minimise the costs (errors and time) imposed by interruptions during assembly tasks in manufacturing.

    Context aware interruptions: Existing research and required research2014Ingår i: Advances in Cognitive Engineering and Neuroergonomics / [ed] Kay Stanney & Kelly S. Hale, AHFE , 2014, s. 260-272Konferensbidrag (Refereegranskat)
    Abstract [en]

    Companies in various fields are developing information systems that are supposed to show information in a context sensitive manner. This involves modifying user interfaces based on the current activity and location of the user. The research that exists for context aware, task aware, and location aware systems come mostly from research in the office environment and using stationary work computers using standard mouse and keyboard-operated systems. Other environments, such as manufacturing environments, have not received the same research attention, and therefore research is required to see whether existing theories and frameworks apply to the manufacturing domain. Adding to this, context aware systems are now being created for new classes of devices such as mobile and wearable devices, to be used in multiple domains. All this requires an investigation and validation of older research, and shows how the research of the basic human factors surrounding new devices and domains has fallen behind the development of the devices themselves. This paper examines shortly how recent changes advances in technology affect what is required from the field of interruption research, as well as what is needed to support other domains than the office environment.

    Coordinating the interruption of assembly workers in manufacturing2017Ingår i: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 58, s. 361-371Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper examines how interruptions from information and communications technology systems affect errors and the time to complete tasks for assembly workers. Interruptions have previously been examined in laboratory experiments and office environments, but not much work has been performed in other authentic environments. This paper contains the results of an experiment that was performed in a simulated manufacturing assembly environment, which tested the effects of interruptions on a manual assembly task. The experiment used existing interruption coordination methods as a basis, and the results showed a difference in the effect of interruptions and interruption coordination between cognitively complex laboratory tasks and manual assembly tasks in an authentic environment. Most notably, the negative effects of interruptions delivered without consideration were smaller in this experiment. Based on these findings, recommendations were developed for designing interruption systems for minimizing the costs (errors and time) imposed by interruptions during assembly tasks in manufacturing.

    Virtual Human-Robot Collaboration: The Industry's Perspective on Potential Applications and Benefits2019Ingår i: Advances in Manufacturing Technology XXXIII: Proceedings of the 17th International Conference on Manufacturing Research, incorporating the 34th National Conference on Manufacturing Research, September 10–12, 2019, Queen’s University Belfast, UK / [ed] Yan Jin, Mark Price, Amsterdam: IOS Press, 2019, Vol. 9, s. 161-166Konferensbidrag (Refereegranskat)
    Abstract [en]

    Two keystones of Industry 4.0 are the increased use of autonomous robots and advanced simulation software. Human-Robot Collaboration (HRC) combines the strengths of humans and robots, opening up application areas that previously could not be automated. However, the realization of HRC on industrial shop floors is held back by several challenges: safety, trust, the need for intuitive interfaces, and design methods. This study investigates the automotive industry’s perspective on relevant application areas and potential benefits of HRC. The data were collected through a survey of 185 participants from a variety of working roles in the automotive industry. The results of the study indicate that participants from the automotive industry consider that the areas best suited to the implementation of collaborative robots are material handling, assembly, and quality control, with potential benefits in ergonomics, efficiency, and quality. The results can be used for the development of a future virtual HRC simulation model.

    Communicating performance measures: Supporting continuous improvement in manufacturing companies2017Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Manufacturing enterprises are a key driver of economic growth (Eurostat, 2016). Implementing continuous improvement (CI) is commonly used to increase competitiveness (Hyland et al., 2007), but despite the well-known theory of CI, many manufacturing companies fail in implementing it (Bhasin, 2012; Nordin et al., 2012; Tiwari et al., 2007).

    An identified critical success factor in CI implementation is the evaluation of performance, including the performance evaluation system itself, the linkage between targets at different company levels, and continual evaluation of performance (Bakås et al., 2011; Scherrer-Rathje et al., 2009; Ukko et al., 2009). Another critical success factor in CI implementation is the communication of performance measures (Bakås et al., 2011; Ukko et al., 2009).

    This research explores the communication of performance measures. The aim is to support CI by improving the communication of performance measures, and to this end, this thesis concentrates on identifying the main challenges in the communication of performance measures supporting CI. The research scope is manufacturing companies in general, and manufacturing SMEs in particular. The relevant literature concerning the communication of performance measures in manufacturing companies is identified and summarized. Also, current practice is explored, focusing on how performance measures are communicated in manufacturing companies, and whether and how the communication supports CI. This has been done to identify divergences between current practice and theory. Finally, theory and empirical findings are synthesized to identify some of the main challenges to be addressed in order to succeed in CI.

    The main task is to support CI efforts in manufacturing SMEs, eliminating the identified divergences in the communication of performance measures by adapting these measures to these manufacturing SMEs. These challenges can be summarized as follows: 

    - using both financial performance measures as well as objective and subjective, non-financial performance measures  - aligning performance measures with strategy and targets  - integrating all performance measure communication, as related to both daily performance and CI, in the same communication loop.  - forming two-way communication channels between managers and operators  - aligning oral and written communication channels  - exploring how information systems can facilitate the communication of performance measures  - using and optimizing the visual communication of performance measures

    Communicating continuous improvement in manufacturing companies: Divergencies between current practice and theory2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    Succeeding with continuous improvement is important for manufacturing companies to increase the competitive edge. In order to succeed with continuous improvement, literature shows that communication of improvement indicators need to be integrated with communication of control indicators. This paper identifies divergencies between current practice and theory in the communication of CI, which can be a reason for why manufacturing companies fail in their CI implementation. An integration of control indicators and improvement indicators could improve continuous improvement results, increasing business performance.

    How to visualize performance measures in a manufacturing SME2017Ingår i: Measuring Business Excellence, ISSN 1368-3047, E-ISSN 1758-8057, Vol. 21, nr 4, s. 337-350Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose - The purpose of this paper is to identify strengths and weaknesses in the communication of performance measures and propose guidelines for the visualization of performance measures supporting continuous improvement (CI) in manufacturing small and medium-sized enterprises (SMEs). The goal is to help manufacturing SMEs improve their communication of performance measures, thereby improving performance, and strengthening the company. Design/methodology/approach - This paper draws on both theoretical and empirical research. It begins with a literature review of theoretical guidelines for the visualization of performance measures. This theoretical information is then supplemented with a case study and a survey, both carried out at the Vara plant, a manufacturing SME with well-developed communication of performance measures. The case study involved all organizational levels in the company and focused on identifying strengths and weaknesses in visual communication of performance measures supporting CI. The information acquired from the literature survey and the case study was then used as the basis for a survey of the employees in one department as regards their perception, understanding and opinion of visual communication of performance measures. The analysis of the results led to the development of guidelines and a substantive proposal improving visualization of performance measures in this specific company, and in manufacturing SMEs in general. Findings - A model for the visualization of performance measures supporting CI in the company was carried out. The guidelines proposed for all such visualizations are as follows: keep the visualization as simple as possible without compromising understanding, use symbols and colors consistently, use simple words and do not include too much information in the visualization. The study also shows that it is important to support a written visualization with an oral presentation to explain the results. Originality/value - The originality of this paper lies in its focus on the visualization of performance measures in manufacturing SMEs and the guidelines and proposals developed.

    Performance measurement communication supporting lean production in SMEs2014Ingår i: Performance management: Designing the high-performing organization, 2014, s. 714-725Konferensbidrag (Refereegranskat)
    Abstract [en]

    Purpose

    The aim of this paper is to provide an overview of the current status of performance measurement communication to support lean production in SMEs.

    Design/methodology/approach

    The paper is based on theoretical and empirical studies. A literature review of existing research in performance measurement communication, focusing on lean production in SMEs, was carried out. The empirical part is based on interviews with both managers and operators in SMEs in the south of Sweden working with lean production. Twenty-four interviews in eight companies / plants were carried out.

    Findings

    The paper provides a structured overview of current research in performance measurement communication. Performance measurement communication was categorised into three parts, which taken together could support lean production implementation in SMEs. It can be concluded that, although all existing research in performance measurement and communication, there is no operational guideline of how to communicate performance measurement. From the interviews it can be seen that the companies have improved their performance measurement communication during the lean production implementation, but that there is no common way of communicating performance measurements in SMEs.

    Performance measurement follow-up supporting continuous improvements in manufacturing companies: a systematic review2015Ingår i: 22nd EurOMA conference: Operations management for sustainable competitiveness / [ed] Gerald Reiner, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Performance measurement has been paid a lot of attention. This paper provides a systematic review of existing research in performance measurement follow-up, which so far has been less treated. The paper suggests a categorization of the follow-up phase into the performance measurement system, input to and output from the system, and operational activities. It is concluded that there is a lack of research concerning the operational activities in the follow-up phase. It is also concluded that most of the research concerning follow-up of performance measurement does not support continuous improvement explicitly, but concerns performance measurement follow-up in general.
