Simulation Design of Express Sorting System—Example of SF’s Sorting Center

ABSTRACT

Original semi-automatic sorting system of distribution center of SF Express is low in efficiency and high in error rate, cannot meet the rapid growth of SF Company’s business needs, thereby, SF plans to build a fully-automatic sorting system. However, due to large investment and high operation and maintenance cost, the fully-automatic sorting system must be designed carefully. For the purpose of checking feasibility of design program, finding out and solving bottlenecks occurred in the operation process of sorting center so that daily express processing capacity of the sorting center reaches more than 150,000 and sorting efficiency of sorting center is improved, Flexsim simulation software is applied to simulation design of the fully-automatic sorting system. After setting the system targets, designing system model and operation model and analyzing simulation result, it is thus shown that planned fully-automatic sorting system meets the design target and the program is feasible.
