Modeling and Performance Evaluation of a Supply Chain via Petri Nets

Abstract – Supply Chains (SC) are distributed manufacturing systems integrating international logistics and information technologies with production. Analytical SC models include discrete event models, that are particularly suitable for the verification of manufacturing systems. This paper presents a discrete event model for SC operational analysis based on timed Petri nets. A case study proposed in the related literature is modeled by way of the presented technique. The Petri net behavior is simulated in order to study the system performance and to compare it with competing SCs
