Multi-product EVSM Simulation

Value stream mapping (VSM) has been a widely used method aiming at the elimination of inefficiencies in manufacturing systems. During the last few years VSM was extended towards the consideration of energy demands of processes and supporting services (EVSM), material use, multi-product perspective, as well as the impact of different product characteristics. However, since VSM is a static method, it is not possible to completely analyze the dynamic interrelations between jobs. This paper proposes a simulation tool which allows the analysis of multiple value streams for different products regarding lead times, as well as non-value adding times and energy demands.
