In the mail processing center planning and design , process design is the key planning and design of the entire mail processing center , will directly affect the mail sorting and opening and turnover efficiency . Process design is a very important part of the construction of mail processing center , through the process flow diagram form , reflect the image of the message from the receiver to the sealing of the process . The process design is the core of the process design , throughout the design process , equipment selection, process calculation , facility layout or work has a direct relationship with the process , the process of design organizations play a decisive role . In this paper, the study mail processing center system , internal technology and processes designed to explore . First , an overview of the mail processing center , put forward the mail processing center and general logistics center difference . Second , the overall planning strategy for mail processing center , mail sorters , push hanging a brief introduction of the system and other processing equipment , general model predictive analysis on the the the important postal equipment sorter grid port number . Finally , pointed out that the principle of the mail processing center process design , process design , the use of the SLP and SHA logistics system facilities planning method to the overall layout of the mail center facilities draw program graph , draw a preliminary process flow diagram , the overall process scheme . Using computer simulation technology and mail processing center process design combine to build simulation models by flexsim to modify the different parameters in the design , modeling and simulation and simulation results are analyzed to seek the general method of mail processing center process design . This modern mail processing center production operating system and distribution centers, process planning and design , has a certain theoretical and practical significance .
