Simulation Of Logistics Distribution Center Operation Management System

With the constant development of economy and continuous spread of the commerce circulation scale, the number of the distribute center is also increasing, which makes the distribution competition more and more sharp. Especially after China entered the WTO, world round larger scale logistics enterprises entered Chinese market in succession, this makes our Chinese logistics distribution competition more fury. As a result, we must apply advanced management methods, create innovation, continuously improve distribution center management level to make our Chinese logistics distribution get a foot in the market. This article brings forward an idea of applying computer simulation to simulate the operation system of the distribution center. It can offer the decision by applying this simulation method.This article has six chapters. The first chapter is introduction. It specifies the research background and significant of this article, introduces the main content. The second chapter introduces the simulation method choice of distribution center operation system. According to the characters and simulation desire of the distribution center operation system, this article adopts a common simulation language, that is GPSS (General Process Simulation System), to simulate. GPSS is one of the most common languages that are used in computer simulation area of disperse field. It is a simulation language orienting process, which makes it adapts to simulate the distribution center operation system. The third chapter systemically analysis the distribution center operation system, explains the operation content, operation flow, the basic regulation of rationally organizing operation process of the operation center, the factors of evaluating the efficiency of operation center in detail. On the basis of the third chapter, the forth chapter more detailed tells the research aim, system confine and the input data needed to be collected of the distribution center operation system simulation. It also provides the flow chart and program plot of the simulation mould, builds the simulation mould of the distribution center operation system. It steers the realization of the distribution center operation system simulation. The fifth chapter carries out the simulation ofa distribution center operation system of shenzhen. In accord with the simulation program of GPSS language, it first analysis the distribution center operation system, points out the problems existing in it. It builds the simulation research aim and system confine according to the actual condition of the distribution center operation system. The second it analysis and deals with the input data gathered by using statistics theory, gets the distributing function of the input data. Then it designs and realizes the program of the simulation module. At last it deals with the output. This is composed of two steps. The first step is to get the output attained the precision requirement, the second step is manages and analysis the simulation result, finds the prime problems existing in the distribution center operation system and the resulting reason, provides the management decision for the development of the distribution center. The sixth chapter gives the conclusion and expects the foreground of China logistics enterprise.This article realizes the simulation of the distribution center operation system according to the practice, by combining with theory analyzing, provides a new thought and method for the distribution center management.
