    Using Mobile Information Sources to Increase Productivity and Quality2010In: Proceedings of the 3rd Applied Human Factors and Ergonomics (AHFE) International Conference / [ed] Gavriel Salvendy, Waldemar Karwowski, Louisville: AHFE International , 2010Conference paper (Refereed)
    Abstract [en]

    This paper presents an experimental study made on the use of different kinds of information sources in manual assembly. The general idea is that only the necessary information should be presented to the worker and it should be presented where and when the worker needs it as this is believed to both save time and unload cognitive strain. To account for the latter two aspects of this thought, where and when, this paper investigates the use of a handheld unit as an information source in manual assembly. Having a mobile information system, such as a Personal Digital Assistant (PDA), that can be carried with you at all times, as opposed to a stationary one, such as a computer terminal, is hypothesized to greatly improve productivity and quality. Experimental results show that the use of a PDA significantly improves quality whereas productivity does not significantly improve.

    Syntax and Sequencing of Assembly Instructions2012In: Advances in Usability Evaluation: Part II / [ed] Francesco Rebelo & Marcelo M. Soares, CRC Press, 2012, p. 266-275Chapter in book (Refereed)
    Abstract [en]

    Minimalism of design is a concept often found in Human-computer interaction (HCI). It is a concept that emphasizes the presentation of as little information as possible to reduce the perceptual strain and visual search of the subject. However, in a manufacturing context, such as in manual assembly, state of the art information presentation is rarely minimalistic. Rather, organizations tend to push out as much information as possible without necessarily concerning themselves with how this information is presented to, or perceived by, the worker. This leads to a situation that is far from ideal from an HCI perspective, likely to reduce human performance and wellbeing, in turn negatively affecting overall production system performance. Obviously, there are several potential ways of addressing this issue. Perhaps the most evident way is to simply reduce the amount of information that is presented and only present the essentials. This paper will investigate and discuss how information presentation can be minimized without reducing the information content through information syntax and layout.

    Abstract [en]

    In current practice, information is often presented to the operators under the false belief that more information leads to better quality. However, one must consider the cognitive capacity limitations of the human operator and design information systems based on these constraints. Important questions include what medium to use; audio, visual, paper based or computer screen systems? Also the syntax in terms of symbols and text, together with information content and the formatting of the system are important factors that will require much focus to result in a good information system. The paper describes a case where paper-based assembly instructions of a major automotive company have been studied, focusing on information design and cognitive ergonomics in information seeking behaviour. Within the case study, the paper-based information system has been evaluated with two focuses: automatic information behaviour (automatism) and consistency of information presentation in the operator graphical user interface (GUI). It is suggested that systems that do not offer clear and easy-to-find entry points to information will eventually cause quality issues in production.

    Applying cognitive science to digital human modelling for user centred design2012In: International Journal of Human Factors Modelling and Simulation, ISSN 1742-5549, Vol. 3, no 1, p. 90-106Article in journal (Refereed)
    Abstract [en]

    To build software which, at the press of a button, can tell you what cognition-related hazards there are within an environment or a task, is probably well into the future if it is possible at all. However, incorporating existing tools such as task analysis tools, interface design guidelines and information about general cognitive limitations in humans, could allow for greater evaluative options for cognitive ergonomics. The paper discusses previous approaches to the subject and suggests adding design and evaluative guiding in digital human modelling that will help a user with little or no knowledge of cognitive science to design and evaluate a human-product interaction scenario.

    A minor field study for combined rainwater andpond harvesting system and purification technology in the village Macedonia, Amazon basin, Colombia2008Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

     

    This study is a bachelor degree project which focuses on the lack of safe drinking water in a small village known as Macedonia in the Amazon basin in Colombia. The inhabitants of the village are 850 to the number and have never had access to safe drinking water. To solve this problem a system has been built where the rainwater is harvested in a pond and also from a church roof

    During the dry season the rainwater in the pond is harvested and pumped into sedimentation tanks. Thereafter, the water is led into the sand filtration tanks. While during the rain season, the rainwater is harvested from a church roof which is situated at highest level in Macedonia. The water is stored in a cistern and then it is led into sand filtration tanks via pipes. This means that the pond water and rainwater are never mixed before entering the filtration tanks.

    The sand filtration tanks contain about 1000 mm thick layer of sand and under it, a layer of gravel which is placed in the bottom of the tank. It takes a while for the water to be filtered through the sand filtration tank. Afterwards, it is led into the final tank, where the drinking water is stored ready to be used.

    The method of using slow sand filtration (SSF) is suitable for small scale-projects and therefore for this project a good idea for making drinking water. SSF requires no mechanical power or replaceable parts, this is why the technique is good for purifying water in developing and isolated areas.

    The result of the system is water with satisfied quality running through pipes and taps, ready to be consumed.

    Utveckling av småskaligt vindkraftverk med vertikal rotor2009Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    When more and more people open their eyes for the climate situation of today, the interest increases for renewable energy. Today there are many highly developed wind turbines with a horizontal axis while the vertically rotating type still is under basic development. Most of the wind turbines today are very big and not adapted for private usage. Through research, idea generation and calculations three new types of vertical axis wind turbines have been developed to compete with the wind turbines for private usage on the market.

    UTVECKLING AV BESLAGSSYSTEM FÖR SANDWICHPANEL: Ett designprojekt i samarbete med Paroc Panel System AB ®2013Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    En av Parocs produkter är sandwichpanel som är ett byggmaterial som kan variera i storlek och tjocklek och är funktionellt och smidigt. Uppdraget var att designa ett beslag för panelsystem som minst 50% av Paroc Panel Systems kunder skulle föredra framför de gamla, främst med avseende på estetiken, men även baserat på lätthet att montera och kostnad av beslaget. Projektet skedde i samverkan med företaget Paroc Panel System AB och ur förundersökningen framkom att utseende, monteringsmöjligheter, egenskaper såsom materials livslängd och hållfasthet och totalkostnad var viktiga krav som ställdes på produkten. Lösningsförslag med fokus på flera viktiga aspekter togs fram och kombinerades till olika koncept med hjälp av en så kallad morfologisk tabell. En konceptutvecklingsfas ingick där hållfasthetsberäkningar och materialval var avgörande. Metoder som DFMA (Design For Manufacturing and Assembly) och LCA (Livscykelanalys) har tagits i beaktande under projektets gång. Detta resulterade i ett nytt beslagssystem med en enkel profil och färre monteringsmoment, något som var viktigt för Paroc Panel System AB. Det nya beslaget hade en gångjärns-liknande fastsättning, vilket innebar att det blev lättare att montera och blev därmed en potentiell konkurrent till dagens beslagssystem.

    Life Cycle Assessment of an Ocean Energy Power Plant: Evaluation and Analysis of the Energy Payback Time with Comparison Between Sweden and Tanzania2013Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Energy is an essential asset in the present society. It is needed for transportation, electricity and heating. Fossil fuels, being a limited reserve, are presently the dominating resource from which energy is being used. As indus-tries and consumers around the world use more energy for each passing day it becomes vital to shed some light on how important it is to decrease the global energy demand. Fossil fuels are needed to be replaced by renewa-ble energy sources, such as solar and wind power, in order to obtain a more sustainable development.When a new product is being developed it is usually important to analyze the potential environmental impact, suggestively by conducting a life cycle analysis, prior to manufacturing. Deep Green, being a tidal energy device for generation of electricity, is a product in its initial developing stage. In this thesis a lifecycle assessment has been conducted of the complete product with the purpose of achieving an analysis of how different choices of materials affect the energy usage, CO2 footprint and the energy payback time. Identifications by comparison have been taken into account to determine which component of Deep Green that contributes mostly to the energy usage and CO2 footprint. In addition to the Life Cycle Assessment, LCA, a digital model, created in an Excel workbook, has been developed to simplify calculations of the energy usage, CO2 footprint and energy payback time. The digital model, namely ENCO©, provides the possibility to interchange choice of materials for each component in order to evaluate the potential environmental impact and the energy payback time. Deep Green consist of 34 different components which are included in the LCA but an initial analysis shows that only twelve specific parts contribute largely to the energy usage and the CO2 footprint. The foundation and the wing structure account for 78 % and 15 % respectively of the energy usage along with ten other parts which together stand for an additional 6 %. Remaining 27 parts share the final percentile. Given the materials provided by the company of Minesto the total energy usage and CO2 footprint for the complete product corresponds to approx-imately 4500 GJ and 342 tonne respectively. The foundation is the part of Deep Green that contributes most to the total environmental impact.Depending on the defined materials for each component the energy payback time varies between 220 to 260 days which is to say that a production of Deep Green would be profitable. Nevertheless the conducted LCA has several delimitations which should be reflected upon prior a final decision is made.The resulted Energy Payback time, EP, should be carefully used and presented with the system boundaries, since they affect the EP very much. The outcome of energy consumption and CO2 footprint, depend highly on the choice of end of life management. Based on the result it is recommended that the foundation is left on the sea-bed at the end of its lifecycle to obtain the best EP.An investigation of whether it is possible to position the complete supply-chain within the boundaries of a de-veloping country, namely Tanzania, has also been conducted along with the LCA. It is believed that most of the raw materials, which are necessary for the manufacturing of Deep Green, are mined in Tanzania. It is however possible to import those materials which are not available within the country. When considering Tanzania, as a point of implementation for Deep Green, the energy payback time will become higher compared to Sweden or England since more components need to be imported which in turn generates an increase of transportation.It is recommended that a new calculation of the EP and the carbon footprint are done when Deep Green is fully developed. ENCO© can advantageously be used for this. It is also recommended that the distribution cables and the installation are included.

    Experimentell studie av reversibel axialfläkt: Med avseende på utformning av nav/skovelbas samt minsta/största skovelvinkel2012Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    In this thesis a new construction of a reversible axial flow fan is being studied. By performing experiments on different variants of a fan wheel an evaluation is done. Factors to be varied are the design of the hub and the blade base as well as blade angle. All tests is performed in a test rig established by AB Akron-maskiner. The test rig is constructed according to ISO 5801.

    Experiments show that the hub design itself does not have a significant impact on the performance. Changes in performance are detected when various combinations of hubs and blade base are tested. The greatest difference in efficiency between the best and worst hub/blade base combination is about 20%. It is of great interest to have access to this information because a simpler design of the hub allows greater flexibility in the manufacturing. An upper limit for the maximum blade angle is partly due to the appearance of stall but mainly the limitations of the fan motor. The minimum blade angle has also the result founding in engine size. The performance is improved if the radial airflow through the blades cavity is blocked. A blockage causes an increase in efficiency by 5-12% and a reduction in sound power level of 2-3 dB. For optimal performance, the design of the hub should be spherical and the blade base curved and shaped to the hub. This is the same type of hub that is produced today. Maximum and minimum useful blade angle is 50° and 25° to the rotation direction.

    Hållbart Inköp: Hur inköpsfunktionen kan bidra till en hållbarare organisation2012Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to analyze how the purchasing function can contribute to a com-pany’s sustainable performance in both the short and long term. Furthermore, the purpose is also to scrutinize how Swedish firms use sustainable procurement today. The study examines that by comparing an empirical investigation of Swedish firms made by the authors to the theoretical frameworks preferred way of working with sustainable procurement, which is es-sentially based on 41 journal articles. This study is of interest since the purchasing function possesses one of the greatest opportunities to influence both the company and its suppliers; this indicates that procurement can play a major role in increasing sustainable development. The use of sustainable procurement can create many advantages for both the company practic-ing, and for the environment. Nonetheless, it is according to earlier studies clear that compa-nies are not taking advantage of the promises found in sustainable procurement. One potential reason companies are not utilizing sustainable procurement is that they lack the knowledge needed to execute a more sustainable purchasing method and also that firms consider sustain-able purchasing as complex and resource intensive.This study explains the fundamental concepts needed to utilize sustainable purchasing; these are green purchasing, social responsible buying and economical responsibility. The conjunc-tion of these three parts constitutes sustainable purchasing.The result of the study is a theoretical framework that highlights the possibilities of sustaina-ble purchasing and provides some overall guidelines for how the work towards it can be con-ducted. The theoretical framework also provides a compiling of the existing litterature to fa-cilitate further studies. The study shows that there exist pure strategies for working towards both environmental and social sustainability. Pure strategies for purchasing towards economic sustainablility where still harder to come by. One clear recognition during the work with the theoretial framework were however that the different parts that makes up sustainable purchas-ing doesn't stand alone, they are rather interrelated. That indicates that it is better to work to-wards sustainability as an overall concept rather than towards its parts. The study also shows how six companies who purports to be working with sustainable procurement does so, and how this conforms to the literature, and how it does not. The found literature on the subject frequently mentions that the biggest problem with sustainable procurement today is compa-nies generally low involvement in sustainability. These problems where however harder to prove in the study. Based on the study, several factors that affect companies involvement in sustainable procurement was identified. Factors such as; company size, line of business, level of globalization proved to affect how the companies work with sustainable procurement.

    Hypothesis test of a new line balancing approach with dynamic allocation of assembly operations2013Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Assembly lines are no longer systems designed to produce as much as possible at the lower cost. Nowadays several factors such as mass customization and variation in demand have led the manufacturers to consider the flexibility of the assembly systems as one of the most important facts to take into account when designing an assembly line.

    In this context, this study attempts to test a new paradigm of the workload balance, which is based on a dynamic allocation of the assembly operations. In order to test the hypothesis, a real assembly system of engines has been used as a base model to implement the new approach. The work developed, uses the simulation as a means to carry out the study, which has required the development of several simulation scenarios. The hypothesis has been studied from two different approaches; on one hand a total dynamic allocation of assembly operations, which was expected to cause a wide operational range of the stations. On the other hand, the second approach implements a flow control which aims to reduce the operational range and workload fluctuations.

    The results obtained show a significant improvement of the system performance in comparison with the current assembly line. It has been found that any improvement implemented in the system is directly reflected in the total performance of the line, regardless if the improvement is made in a system constraint. Moreover, the results have proven a better response of the system to changes in the frequency of models production. 

    Finally, based on the results, this study suggests several paths of future work in order to acquire the needed information to implement the hypothesis in the real world context.

    Framtidens TV-fäste: Ett projekt i samarbete med People of Lava Sweden2011Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Rapporten behandlar en produktutveckling av framtidens TV-fäste. Teknik och form hos TV-apparater utvecklas varje dag, detta leder till att TV-fästen måste anpassas för att följa trenderna. I samarbete med företaget People of Lava har en designprocess utförts för att utveckla framtidens TV-fäste.

    Rapporten behandlar en djup marknadsundersökning där statistiska, kvalitativa samt kvantitativa undersökningar utförs. Detta ligger sedan som grund för en target cost där ett produktionspris söks för att försäkra sig om en önskad vinstmarginal för företaget. Utifrån den bestämda kostnaden genomförs konceptgenereringar där form och funktioner utvecklas. De genererade koncepten utvärderas via konceptvalsmatriser och diskussion med såväl företaget som möjliga köpare av produkten.

    Resultatet av processen är ett TV-fäste som inte är anpassad till den standard som vanligtvis används hos TV-fästen. Ett exklusivt fäste med integrerad förvaring som står ut på marknaden och blir en del av inredningen. Fästet erbjuder företaget en miljövänlig tillverkning i Sverige, då närproducerat material valts för produkten.

    Kommunikation mellan offentlig och privat sektor: En studie mellan Mariestads kommun och dess företag2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose off this thesis is to improve the communication between the local authority of Mariestad and the companies in the community to be able to improve the business climate in Mariestad municipality. To achieve this purpose two research questions have been examined. Which Channels are used when the local authority communicates with the companies in the community and how does the communication function between the local authority and the companies. An interview was done. The interview was one part of the foundation to the survey that was done which was sent to 211 stock corporations in Mariestad community. In the survey the companies were divided in different groups according to size.

    The results from the survey showed that the communication channels which are used in the communication between the local authority of Mariestad and the companies in the community are the local newspaper, letters, information meetings, telephone, mail, the local authority’s homepage and personal visits.

    It showed that the communication between the local authority and the companies was of significant importance for the business climate. The companies thought that the local authorities contribution to the business climate were not so big. The local authority had not succeeded to a large part to catch the companies’ interests and attention.

    The communication channel that the companies wanted the most was personal contacts (visits).The companies thought that personal visits were the channel that was used most seldom off all channels. Big companies and middle-sized companies thought that personal visits were the channel that functioned worst off all channels. The channel which big size companies and middle size companies’ thought functioned best today was the local newspaper. No matter which communications channel used, middle-sized companies thought that communication functioned best today of all company seizes.

    Vad är ett lokalproducerat livsmedel för dig?2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Konsumenter i Sverige i dag har stor tillgång på livsmedel och mat från hela världen. Möjligheten till att välja och vraka i sitt val av livsmedel och att inte behöva fundera över om det är säsong eller inte ställer högre krav än tidigare på våra svenska producenter. De måste producera mer och marknadsföra sig tydligare. Det visar sig i vår undersökning att ett stort antal konsumenter väljer att handla lokalt producerade livsmedel, mycket med hänsyn till den lokala producenten. Att handla lokalt är ett sätt att överbrygga avståndet mellan producenten och konsumenten och att bevara mångfalden. Syftet med uppsatsen var att visa, ur ett konsumentperspektiv, vilka kriterier som ska uppfyllas för att svara på frågan vad ett lokalproducerat livsmedel är och om det fanns faktorer som väger tyngre än andra. Lokalproducerat är ett begrepp som används ofta men som inte är officiellt definierat. En allmän definition är att livsmedlet ska produceras och konsumeras inom ett visst område. Resultatet av undersökningen visade att begreppet lokalproducerat i stort sett bara stod för positiva mervärden för respondenterna. Undersökningen kan sammanfattas i tre ord: närhet, märkning och mervärde. Närhet innebar för våra respondenter att de vill ha tillgång till lokalproducerade livsmedel i sin livsmedelsbutik och det avstånd ett livsmedel som längst ska få ha transporterats. Tidigare var det inga funderingar om var ifrån livsmedlet kom och detta, känslan av att veta livsmedlets ursprung, är något som idag efterfrågas av många. En märkning där det tydligt framgår ursprungsland eller den lokala producentens namn stod högt upp på våra respondenters svar. Många såg ett mervärde i att handla lokalt producerade livsmedel vilket visade sig tydligt i undersökningen. Ord som lycka, närhet, god kvalité och kortare transporter lyftes fram.

    Theoretical Integration and Unification: A Focus on Justice2007In: Social Justice Research, ISSN 0885-7466, E-ISSN 1573-6725, Vol. 20, no 3, p. 263-269Article in journal (Refereed)
    Abstract [en]

    A commonly shared goal among scientists is to reach the ‘holy grail’ of theoretical integration or unification. We list several examples of such attempts within sociology and psychology in general and, more specifically, within the subarea of social justice. A distinction is made between the seemingly interchangeable terms integration and unification. We note the scarcity of work concerned with untangling the meaning of theoretical integration, with differentiating among forms of integration, and with mapping the variety of ways in which integration might be accomplished. The five articles published in this issue of Social Justice Research, and here briefly reviewed, address these and related questions and/or exemplify theoretical integration with a focus on justice.

    Advances in Justice Conflict Conceptualization: A New Integrative Framework2012In: Justice and Conflicts: Theoretical and Empirical Contributions / [ed] Kals, E. & Maes, J., Berlin, Heidelberg: Springer Berlin/Heidelberg, 2012, p. 21-52Chapter in book (Refereed)
    Abstract [en]

    A thorough understanding of conflicts is crucial as conflicts may be destructive to the welfare of individuals, groups, and societies. Conflicts are closely related to justice concerns in that perceived injustices give rise to conflicts and destructive conflicts give rise to injustices. However, the notion of conflicts is rather underdeveloped and the definition of it often taken for granted in justice theory and research. In this chapter we propose a useful conceptualization and classification of justice conflicts. Specially, five types of conceptual distributive justice conflicts, five types of social distributive justice conflicts, and three types of a mixture of both are defined and described. Some of these basic types, in turn, encompass two or more subtypes of conflict. These result in different dilemmas and processes, the natures of which are likey to have important implications for conflict resolution. The present chapter highlights several shortcomings of current conceptualizations of justice conflict, and provides a new integrated framework for a more systematic approach.

    Introduction. Social Resource Theory: Yesterday, Today, and Tomorrow2012In: Handbook of social resource theory: theoretical extensions, empirical insights, and social applications / [ed] Kjell Törnblom, Ali Kazemi, New York: Springer, 2012, p. 1-12Chapter in book (Refereed)
    Abstract [en]

    Following a Foreword by Morton Deutsch and an Introductory chapter, this handbook presents five parts containing a total of 26 chapters and concludes with an Envoi by Elaine Hatfield and Richard Rapson. The introductory Part I contains two chapters: In Chap. 2 Foa and Foa present the basic framework of their social resource theory, and Chap. 3 spells out a number of issues that may need to be addressed for its further development. Part II contains seven chapters discussing various conceptual and theoretical elaborations of SRT. The five chapters of Part III describe attempts at theory integrations between SRT and other models and theories. Part IV features six chapters describing various applications of SRT on different levels, from the organizational to cross-cultural. Finally, the six chapters of Part V focus on various justice aspects in the distribution of different kinds of resources. This simplified characterization of the chapters conceals the fact that many of them would also fit under other parts of this book; the contents of each chapter are certainly more varied and richer than indicated here.

    Justice Judgments of Physical Abuse and Theft: The Importance of Outcome and Procedure2010In: Social Justice Research, ISSN 0885-7466, E-ISSN 1573-6725, Vol. 23, no 4, p. 308-328Article in journal (Refereed)
    Abstract [en]

    The perceived justice of a situation is frequently a function of both outcome and procedure, but the importance of each may vary when making justice judgments. This study investigated the impact of type and severity of offence, social relationship and status on the perceived importance of the outcome and procedure for justice judgments. The outcome was considered more important than the procedure for judgments of both theft and physical abuse, regardless of offence severity, status of the offender and the victim-perpetrator social relationship. Both outcome and procedure were viewed as more important for judgments of physical abuse than theft. Data obtained for exploratory purposes yielded no correlation between ratings of justice and importance, indicating that the two are not aspects of the same construct. Integrations with work within criminology are discussed.

    Some Conceptual and Theoretical Issues in Resource Theory of Social Exchange2012In: Handbook of social resource theory: theoretical extensions, empirical insights, and social applications / [ed] Kjell Törnblom, Ali Kazemi, New York: Springer, 2012, p. 33-64Chapter in book (Refereed)
    Abstract [en]

    This chapter by Törnblom and Kazemi discusses a number of issues in SRT which seem to benefit from further developments. Specifically, they ask whether the Foas’ resource classification meets the criteria for a typology, whether there are other dimensions than concreteness and particularism and whether the Foas’ six resource classes can be categorized into subclasses. Törnblom and Kazemi further discuss the validity of some of the exchange rules that the Foas formulated. They also extend the Foas’ two basic behavioral modes of giving and taking into four basic modes of exchange (i.e., giving-giving, giving-requesting, requesting-giving, and requesting-requesting), and this opens up for a host of further distinctions when additional facets like resource valence and resource type are included. Additional issues discussed in this chapter involve the production and acquisition of resources, different types of linkages between the production, acquisition, possession, and provision of resources, and finally the relevance of SRT to the topics of social justice, social exclusion, well-being, social dilemmas, social comparisons, and volunteering. Some of these issues are the focus of several chapters in this handbook.

    The relative importance of outcome and procedure for total justice judgments2009In: Dynamics Within and Outside the Lab: Proceedings from the 6th GRASP conference, Lund University, May 2008 / [ed] Stefan Jern & Johan Näslund, Lund: Lund University , 2009, p. 184-202Conference paper (Refereed)
    Abstract [en]

    Contemporary justice theorists assume that a meaningful assessment of fairness in interpersonal encounters requires assessments of the outcome (the end result) as well as the procedure (the means) by which the outcome was accomplished. This study investigated the relative impact of four variables on the subjective importance of the outcome and procedure for total fairness evaluations, using a 2x2x2x2 factorial survey design: Type of offense (physical abuse vs. theft) x Severity of offense (moderate vs. serious) x Social relationship (particularistic vs. universalistic) x Status of the perpetrator relative to the victim (equal vs. superior). Results suggest that the outcome is considered more important than the procedure for fairness judgments of both offenses, regardless of their severity, relative status of the offender, and the social relationship within which the offense was committed. Furthermore, both outcome and procedure were viewed as more important when assessing the fairness of physical abuse as compared to theft. For the physical abuse offense, this was more likely to be the case when the status of the offender was superior to the status of the victim.

    Abstract [en]

    The aim of this paper is to formulate new and more precise predictions regarding behavioral reactions to distributive and procedural injustice via insights from resource theory. The three theories share focus on discrepancies between actual and ideal states of existence as well as on psychological and behavioral reactions to discrepancy. But they also differ from each other in their conceptualizations and theorizing about these matters. Equity theory conceptualizes discrepancy as a perceived mismatch between inputs and outcomes; multiprinciple distributive justice and procedural justice theories view discrepancy as a mismatch between expected and applied distribution and procedural rules, respectively. Resulting feelings of inequity/injustice may trigger attempts to restore justice. Within the framework of resource theory, discrepancy concerns an inappropriate match between the nature of the provided and received resources. This leads to frustration which, in turn, may trigger attempts at retaliation. Limitations of the theories are discussed, with particular focus on their inability to match specific discrepancies with appropriate behavioral reactions. Behavioral predictions are based upon established congruence between behavioral reactions and violated procedural rules as well as type of inequity, as determined via their respective resource isomorphism. Limitations of the present integration attempt are discussed.

    Improvement of sampling system for Remote Explosive Scent Tracing2010Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Remote Explosives Scent Tracing (REST) is the concept of bringing the mine field to Mine Detection Dogs or Rats, instead of vice versa. This is done by collecting air or dust from minefields, and taking these samples to a laboratory environment, where they are subsequently analysed by the detection animals.

    REST has previously proven to be very fast and cost effective, but one of the issues facing the method is that there is yet no reliable tool for sampling dust. In earlier sampling units, air has been collected in filters. However, the concentration of scents related to mines has been seen to be a million times higher in dust particles than in air sampled from above the ground. The aim of this project was to evaluate and improve a dust sampling prototype constructed in the beginning of 2010. The project was initiated in cooperation with the GICHD (Geneva International Centre for Humanitarian demining), and carried out in cooperation with APOPO (Anti-Personnel Landmines Detection Product Development).

    During this project, information was gathered on the samplers that have previously been used for REST. A new prototype was made in Trondheim in cooperation with NTNU (Norwegian University of Science and Technology). With this new sampler prototype, tests were made in a laboratory environment at NTNU as well as at APOPO’s test mine field in Morogoro, Tanzania. Several obstacles were faced, such as difficulties to test and evaluate the sampler during the rainy season, insufficient air supply for the prototype, and issues with the laboratory equipment in Morogoro. Due to this, the number of tests performed and the number of repetitions of each test was not as high as would have been desired.

    The results of the information gathering and the tests are presented in this report, and the knowledge and experience gained resulted in several suggestions for improvements for the sampler prototype. A suggestion for a grid design that would cover the entire mouth piece, with a built-in distance to the suction inlet, in order to avoid both clogging of the grid and that too much dust is sucked in if the mouth piece touches the ground and a fully adjustable sampling unit. Several other recommendations are given that would reduce cross contamination risks and improve ergonomics and other aspects of the sampler prototype.

    Advanced manufacturing simulation: Minor system details can be major issues in the real world2006In: Industrial management + data systems, ISSN 0263-5577, E-ISSN 1758-5783, Vol. 106, no 8, p. 1166-1186Article in journal (Refereed)
    Abstract [en]

    Purpose – This paper aims to highlight the complex nature of automated guided vehicle (AGV) simulation model building, and especially how system modelling details affect the end results. This is an important issue in all of the transportation simulation systems, since they are service-based by their nature, and additional inefficiencies create unanticipated performance downgrading.

    Design/methodology/approach – This paper uses a simulation approach, and simulated systems are based on a real-life case study and on well accepted hypothetical simulation example.

    Findings – Simulation system boundaries are often neglected in the model building, and especially interface to inbound (and possibly outbound) material flow should be considered carefully; based on these research results, AGV investments are seen in an entirely different light, as system boundary is enlarged to contain more realistically interacting elements. Similar system boundary issues were found from the case study: interface with overhead gantry did not provide near optimal performance. The case study also revealed that high speed of AGVs is not necessarily worth additional investment; constraints exist in safety, acceleration and ability to turn in corners.

    Research limitations/implications – The findings are based on the simulation work and, to see the real implications, real-life implementations on policy level are needed.

    Practical implications – Results of this research provide more insights for manufacturing unit investments, and especially in the scope of automated transportation system use. Also changes in manufacturing flow management issues, after investing in, for example, AGV systems, are different from in less-automated manufacturing units.

    Originality/value – This research work provides more insights to simulation research work, especially from the perspective of transportation systems. Also implications arising from case study are unique as being compared to previous research in the field.

    Semi-autonomous vehicles with routing flexibility: functionality and application areas2009In: International Journal of Services and Operations Management, ISSN 1744-2370, Vol. 5, no 4, p. 444-462Article in journal (Refereed)
    Abstract [en]

    Automated Guided Vehicle (AGV) systems are standard automated items in production and warehousing today. However, studies have rarely examined a more advanced form of AGVs called Semi-Autonomous Vehicles (SAVs), which have a higher sophistication of task completion and routing flexibility. This research presents SAVs in an industrial development case study. Using simulation, the route-keeping ability of SAVs with two types of guidance techniques is being studied. The results show that dual-navigation SAVs can provide the needed flexibility for routing. Using wire guidance and dead reckoning, both very well-established techniques, the SAVs' performance is, within certain limits, quite comparable to the AGVs with more advanced and expensive navigation techniques.

    Simulation of Automatic Guided Vehicle systems in manufacturing environment: Case: Volvo's Crankshaft Unit in Skovde2008In: International Journal of Manufacturing Technology and Management (IJMTM), ISSN 1368-2148, E-ISSN 1741-5195, Vol. 15, no 1, p. 45-63Article in journal (Refereed)
    Abstract [en]

    Competing in global markets creates pressure for manufacturers to rigidly use automation, and advanced manufacturing techniques to improve manufacturing plant productivity. Among productivity, manufacturers are also interested about other performance dimensions, namely time, flexibility and quality. With the wise use of automation, we could directly improve all of the other indicators, and indirectly quality. In this paper it is shown, how implementation and use of Automatic Guided Vehicles (AGVs) could benefit from the use of manufacturing simulation. AGVs have been available for practical use since the 1970s, but still in the investment and use processes it is rarely seen justified to a high detail, what eventually determines the number of vehicles used in the system. Our paper is able to show with two simulation cases (a hypothetical example and a real case study) that the number of AGVs is very sensitive with respect to production system output. Furthermore, some assumptions that are often made can overly simplify the problem (e.g. no recharging of batteries and constant speed). Therefore, in this paper, we propose that more research should be addressed to the AGV system simulation, and in practice tools for decisions makers should be developed further. Our research also shows that empty travelling and low utilisation is a norm in current AGV systems in order to assure production system functionality, and there is a need and potential for performance improvement here, as well.
