Research on modelling and simulation of enterprises logistics system based on timed coloured Petri net

Rationalization of the Production logistics system can reduce logistics costs and lower product costs. In current, experience and analogy-based approach is still the main way enterprise planning scheme for logistics system. Petri net is an important tool for discrete event system analysis. Papers proposed method which modelling and simulation of plant logistics system based on timed colored Petri net. By use of simulation methods to conduct a comprehensive analysis and plan selection for the logistics system, and optimize planning and parameters of enterprise logistics system, providing a reliable basis for the choice of programmes. Application exSpect software simulation for different logistics plan expansion of automotive enterprises, which analysis and comparison the results of simulation output.
