Abstract [en]

This paper describes the factors that play a role in credibility of simulation results. It focuses on virtual manufacturing and in particular resource simulation as an example. However, a simulation model can be used in a number of different ways. Verification and validation of models is amongst other factors important for credibility. In this area, much work has been carried out in defense research. There are also some striking similarities between virtual manufacturing and information fusion, in particular in the field of human competence development related to credibility of simulations.

Abstract [en]

This chapter gives a general description of simulation and its associated system of interest. In the context of virtual manufacturing, three domains can be distinguished; product domain, process domain and resource domain. Examples of simulation in these three domains are given, as well as some examples of simulation across these domains. Typical steps/phases in a simulation project are described, as well as common pitfalls. In industrial simulation projects, usually a number of stakeholders are involved with different maturity/experience in the field of simulation. It is described how such industrial simulation projects can be supported by a handbook, developed in close collaboration with a group of companies. As one example of advanced applications, simulation-based remote monitoring and diagnostics is described. The other example of advanced applications given in the paper is that of simulation-based optimisation. Many simulation tools and projects aim at providing decision support to a human decision maker. High level information fusion, a development originating from defence research, also aims at providing decisions support. A comparison between virtual manufacturing and information fusion reveals that a popular reference model for information fusion called JDL-model is very apt to serve as a reference model for virtual manufacturing.

Abstract [en]

This paper presents a description of Modelling and Simulation as used in the Virtual Systems Research Centre at the University of Skövde. It also gives a summarized account of issues discussed in previous work such as phases in a simulation project, Verification, Validation and Accreditation, and the use of simulation as a tool to reduce uncertainty. The role of the human in various phases/activities in simulation projects is highlighted. Examples of both traditional and advanced applications of Virtual Manufacturing are given. Examples of the latter are simulation-based monitoring and diagnostics, and simulation-based optimization. Two models for Information Fusion, the OODA loop and JDL-U model, are discussed, the latter being an extension of the JDL model that describes various levels of information fusion (JDL=“joint directors of laboratories”). Subsequently, the activities and phases in a Modelling and Simulation project are placed in the context of the JDL-U model. This comparison shows that there are very strong similarities between the six (0–5) levels in the JDL-U model and activities/phases in Modelling and Simulation projects. These similarities lead to the conclusion that the JDL-U model with its associated science base can serve as a novel reference model for Modelling and Simulation. In particular, the associated science base on the “user refinement” level could benefit the Virtual Manufacturing community.

Abstract [en]

Electricity prices have gone up significantly during the last decade, and in some countries, the electricity price is very volatile. There exist a number of policies and regulations to control the electricity market and to stimulate energy efficiency, but these are often not very transparent. Furthermore, indicators for energy efficiency can be misleading or difficult to measure. Although there are a number of approaches to modelling and simulation of energy consumption and energy optimisation, these approaches have some drawbacks such as prohibitive computing times, difficulties to address dynamic situations, and the lack of a holistic view on the manufacturing system. Other problems include the limited availability of data at the appropriate level of aggregation; sometimes the level is too low, in other cases too high. However, recently promising attempts have been made to use Discrete Event Simulation for energy modelling and production planning. It is believed that this, in combination with other ICT tools such as multi-objective optimisation, offers a promising way forward beyond current state of the art.

Abstract [en]

This paper proposes a novel low-cost robotic telepresence approach to situation awareness, initially aimed for hazardous environments. The robot supports omnidirectional movement, wide field of vision, haptic feedback and binaural sound. It is controlled through an augmented virtuality environment with an intuitive position displacement scheme that supports physical mobility. The operator thereby can conduct work away from danger whilst retaining situation awareness of the real environment.

Abstract [en]

Manufacturing organisations are continuously forced to improve the way of working to maintain their competitiveness on the global market. To optimize a production facility requires not only an optimal design of the whole line but also its internal operations sequencing and scheduling during the operational phase. The use of Virtual Manufacturing tools such as Discrete Event Simulation and Computer Aided Robotics has been proven to be highly effective both for production system design and for operational analysis and improvement. This paper proposes a new optimisation method, named SIMBOSeer, which synergistically combines the areas of optimisation, flexibility and virtual manufacturing that integrates robot simulation with simulation-based optimisation. Evaluation of SIMBOSeer, as applied to an existing manufacturing cell at a powertrain manufacturing company in Sweden, has shown that it can be used as an iterative process of analysis and optimisation. The results, when using realistic what-if scenarios, clearly point out that SIMBOSeer can facilitate the optimisation of operation sequences and decrease the total cycle time of the manufacturing cell. This is due to the fact that many non-value adding functions, such as unnecessary tool changes, which have a great negative impact on the effectiveness of the flexible manufacturing cell, can be avoided. Whilst the use of SIMBOSeer has obvious advantages under normal operating conditions of the cell, its use become even more beneficial when disturbance like tool failures occur or when product variants are introduced to the cell.

Abstract [en]

This paper presents an overview of important aspects of air bending of sheet metal parts. Air bending is potentially a very flexible process when it comes to processing small batch sizes with high variety. However, to exploit these benefits requires that both the processing of individual bends and the overall processing of a part be executed adequately. Important aspects are the bending process itself, in particular modeling and the calculation of punch penetration and bend allowance, the determination of bending sequences, and tolerance reasoning. Some problems related to spring back in the air bending may be solved by combining it with for instance laser forming. Some problems related to bend sequencing or accuracy may be solved in the design stage.
