[Abstract]:China's logistics industry as a whole presents a rapid development model, but with the increasingly fierce market competition, the logistics industry is also facing a great crisis, warehousing as the core part of logistics activities, Its management condition will affect the efficiency and benefit of the whole logistics system. Scientific and reasonable facility planning in storage system can fully integrate manpower, material resources, equipment and resources, simplify logistics process and improve logistics efficiency. Logistics simulation is mainly based on computer technology to simulate the logistics system. Through simulation experiments, various dynamic activities and processes can be recorded instantly to verify the effectiveness, rationality and optimization of logistics project construction. This paper mainly takes DC corn warehouse as the background, applies SLP (systematic facility layout) to carry on the scientific and reasonable layout to its operating unit, and uses Flexsim software to carry on the simulation research to its system, Find out the bottleneck of warehouse system and improve the whole logistics system. This paper first introduces the research status of warehouse management and logistics system simulation at home and abroad, secondly, introduces the storage function and storage management principle, and describes the nature of DC corn warehouse. It lays the foundation for the later optimization. Then the composition of logistics system simulation, especially discrete event system simulation, is analyzed, and then the generation, function and characteristics of Flexsim software, terminology and basic modeling steps are introduced in detail. This paper mainly takes the warehousing system of DC Company as the research object, finds out the problems in management, layout and facilities, and puts forward some suggestions on how to improve the system by using the theory of industrial engineering. The relationship between logistics and non-logistics in warehouse system is analyzed by SLP method, and the layout of each unit is optimized by synthesizing various factors. Finally, the Flexsim software is used to simulate the corn warehouse of DC Company, and the concrete operation flow of entering and leaving the warehouse is analyzed. By abstracting and simplifying the real physical system, the simulation model of the storage operation system is established, the model parameters are set up and the simulation operation is carried out. The results of 3D model are analyzed. According to the characteristics of corn storage and the principles of storage management, the irrationality of the system model is analyzed, and the optimization method is established to improve the model and run the optimal model many times. Reduce storage cost and labor intensity of staff, improve storage efficiency.
