Abstract: The current situation of a food processing plant in the original distribution center is introduced,using qualitative analysis and quantitative calculation to analyze the comprehensive relationship among the functional areas.Based on the factors of market demand,logistics,supply and demand analysis and other factors,the scale of the main working area of distribution center is determined.System layout design method is used to carry out scientific planning and layout for each operation area of the new distribution center of the enterprise.Using Flexsim simulation software to simulate the layout of the distribution center plane area,the logic flow between the function area of distribution center acceptance area,circulation processing area,sorting area and other areas is established,and the parameters are set to realize the compiling and running of the simulation model.The simulation results are analyzed in order to realize the prediction of the working efficiency and the optimization of the operation and to save the manpower,capital and resources cost.

Key words: distribution center, facility planning, Flexsim simulation
