At present, simulation of logistics in china has become important. Due to lack of planning system, we can see irrational phenomenon everywhere, so it is difficult to bring profit to the enterprise. Whit the development of the computer, the technology of computer simulation is a good way to study the logistics system. The biggest advantage is that we can compare the different plans base on Flexsim and find out which is the best choice without cost. This paper researches the key technologies which build the simulation platform about the logistics system base on Flexsim in detail. The paper uses the VSM to find out the problems which existed in the logistics system, and optimize the logistics system.
KEYWORDS:Simulation model, Flexsim , Optimization, Value stream mapping
