Optimization of production logistics process of automobile manufacture enterprise based on Petri net

The production logistics process of the modern automobile manufacture is a complex, dynamic and stochastic process of logistics, information flow and capital flow. Taking the production logistics process of a domestic large-scale automobile manufacture enterprise as research object, a model of production logistics process in the present environment was built using the Petri net technology, whose mathematical characteristis was analyzed, and the strong and weak points in the original and the optimized processes were discovered by the simulation using the software Exspect. The results show that the optimization of the original process flow by information technology reduces effectively the probability of mistake and fault in the system operation and enhances the system work efficiency.
