Simulation and Optimization of a Kind of Manufacturing PackingProcessesChun-youLiCollege of Transportation Logistics, CSUFT, Changsha, HN, ChinaAccounting School, GXUFE, Nanning, GX, China(lcy0731@)Abstract - There’re many factors that influence each other in production-packaging processes. Resources, objects, processes and their properties behaviors can be simulated to construct a computer simulation model across the whole production-packing process. Usually, the minimized cost, maximized profit or reasonable utilization was targeted as the decision objective, and concerned parameters was configured as conditions in the simulation model. With enough repeated runs, the optimization module can seek the best equipment combination and the best production schedule.Keywords - Manufacturing packing, Simulation, OptimizationI. INTRODUCTIONIn some industries such as food tobacco industry, the terminal product is generally made from the production line and packaged into small boxes or small bags. The basic process is to produce these products through one or more production lines, and delivery or transfer products to packaging. Finally, the small-packaging products are filled into a larger container through one or more packaging equipments continuously or partially and gotten out the lines. Fig.1 is the schematic diagram of such production and packaging process, two manufacturing lines produce the same kind of products, then transfer them to three coordinate packing lines through a series of buffer vessels, finally package them into finished goods. Fig.1.the schema of production packaging processIn cases such as designing and recreating a new packaging process or managing an existing process, we often have to face the following questions as: how to reduce process failure? How to reduce the processing cycle time? How much is the reasonable buffer capacity and the buffer stock? How to deal with the change of production scale? And is it necessary to add more and higher ab
