Simulation Modeling Based On The FLEXSIM For Logistisc Distribution Center

Simulation of logistics in China has gradually become important. Due to the lack of accurate data and the necessary logistics decision supporting system,Logistics enterprises facing with the investment of new projects or technological transformation of the original system, always cause blind investments and financial loss. Taking advantage of simulation technology and dynamic simulation of different activities, we can follow the process of an instant recording and verify the effectiveness of the logistics project, and also examine the reasonability of the logistics simulation. In this paper, I take DHL Beijing distribution center for study and combine with Flexsim simulation system, the work carried out by the following:The first step, analysize the functions, structure, processes and management control of the distribution center. Summarize and integrate the typical pattern distribution centers. Then conclude the function of the dismantling structure and standardize the system model of the core distribution centers. According to the structure model and the theory of simulation modeling, summarize the general ideas and basic plans of designine distribution centers. Finally, through the theoretical study and practical experience on the basis of proposed distribution centers, simulation modeling process should be guided by principle.second step, using the OpenGL process modules which focuse on distribution centers to achieve simulation modeling techniques, including logistics equipment simulation modeling technology, process control scheduling and construction methods.Third step, established core subsystems of the parameters of simulation models, such as AS / RS system, AGV system, DPS intelligent sorting system and The PAS system by following the principle...
