Modeling and analysis of supply chain under uncertain market circumstance using ECGSPN

The paper mainly focus on how to establish a model to analysis developing trends of profit and stocks of supply chain under uncertain market circumstance. The Petri net model available concentrated on analysis relationship between number of tokens and time delay of transitions. In order to solve the deficiency of analyzing developing trends of profit and stocks of supply chain under uncertain circumstance, a model based on extended colored general stochastic Petri nets (ECGSPN) was proposed in virtue of PCPN (price colored Petri net) and FSPN (Fluid stochastic Petri nets). Comparing with models available, the supply chain model using ECGSPN can describe impact of stochastic market circumstance on developing trends of profit and stocks of supply chain efficiently. Some measures was proposed on how to decrease negative impact of stochastic market circumstance on developing trends of profit and stocks of supply chain according to simulation results.
