Performance analysis of supply chains using discrete event systems formalisms

In this paper, we present a new framework for modeling supply chains (SC) using a class of uncertain timed Discrete Event Systems (DESs) modeled by Timed Automata with Guards (TAGs). We also introduce an analytical approach based on dioidalgebra for the temporal performance evaluation of these systems.Specifically, by using the representation of extremal behaviors of TAGs with Min-Plus algebra, we determine the optimal completion intervals for the logistic chain.
