| The major problems of modern logistics in China are that modern logistics system is faultiness and the operational process is irrationality. The self-form logistics system is difficult to guarantee its dependability, rationality, harmony and optimization in the deployment of the logistics resource and in the configuration of logistics network, etc. because of the lack of forecast and system layout. The theory of optimization is difficult to be used in the logistics operational process, so it is hard to produce "the third profit".The main reason not to use the theory of optimization is the complexity of logistics system, so simulation can be appropriate. It reproduced the fact in the computer circumstance by program instead of constructing a real system to be analyzed. Thus, the cycle of design is reduced, the cost of design is debased and the quality of design is enhanced.The paper mostly talks about the usage of simulation method in the logistics system. It also contains the compilation of simulation program which could be use as a tool of assisting decision and system optimization. The paper is divided in four parts: introduction, straight matter, conclusion, reference.The introduction talked about the source, value and the research actuality in the logistics system simulation. In chapter 1 we introduced the basal concept of logistics system and the basal knowledge. In chapter 2 we explained the simulation technology of logistics system. It mainly introduced the summarization of system simulation, the base of system simulation, the system simulation of discrete distribution, and the base of simulation language. In the chapter 3 we discussed the modeling of enterprise logistics system. We set up the general system modeling and established the simulation flow chart of every module. Chapter 4 introduced the arithmetic analysis and the program design of the simulation module. We get the costing by the data statistic in enterprise logistics system. Chapter 5 analyzed the simulation result through the example. In chapter 6, we explained how to install and use this simulation system in order to conduct users to utilize this system. |
