Site Planning Of The Logistics Distribution Center And Modeling And Simulation Of The System

In the modern logistics system, a logistics distribution center is formed of information flow and cash flow as one of the flow-type node .It is an important part of modern industry. Distribution center location and construction planning is an important task of the logistics system. Address a reasonable choice of distribution centers and build the system model, simulation work processes can meet the need of operational requirements and can reduce costs and improve service levels.In this paper, a household electrical appliance enterprises in Nanjing logistics and distribution center for the study, based on the analysis in the investigation, using the minimum cost method of regional logistics and distribution of the business center of the site, by making the transportation cost is minimized to get the most comprehensive efficiency as the goal, the establishment of the location model for the enterprise to achieve the maximum benefits for the company's site made reference to recommendations.In-depth analysis of distribution processes based on Petri nets using the time of analysis to establish distribution centers were purchasing, storage, sorting, picking and other operating systems of TPN network model, it is a complex system of equipment and logistics processes for more rational and efficient layout planning and analysis as an important means to demonstrate the rationality of the modelThe author uses Flexism simulation software with the logistics of the distribution system to the center of the three-dimensional animation workflow simulation, identify the system to plug the "bottleneck" is located, and optimize the system for a reasonable improvement.In this paper, the minimum cost method used in the theory, applications Timed Petri net modeling and simulation software for distribution system Flexism Center processes of research methods, the same applies to research the field of logistics with other characteristics of stochastic dynamic systems, such as: logistics warehousing system operations, logistics and so on inventory system.
