Simulation-based evaluation of performance benefits from flexibility in assembly systems and matrix production

Abstract

This paper contributes to a novel approach for analysing and quantifying the benefits for reconfigurable cellular manufacturing and assembly systems (RCMS/RCAS), also known as Matrix production, based on modelling and dynamic simulation.International market trends concerning consumer behaviour and demand result in increasing flexibility requirements, which conventional production lines struggle to meet, thus creating the need for flexible production and assembly systems such as Matrix production. The flexibility results in additional variables and thus a more complex system behaviour. To utilize its benefits, the design and setup of a matrix production is crucial and for potential real-world applications. However, methods to quantitatively assess beneficial features of a matrix production are only beginning to appear in the literature, making decision-making for a production system transformation challenging. This paper contributes a simulation-based approach to analyse the performance benefits of matrix production using modelling and dynamic simulation. The method is demonstrated with a simplified automotive assembly use case for a dynamic multi-variant production. The results confirm the feasibility of the method and quantify the potential for increased assembly system performance gained from specific flexibility features in a matrix production.
