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

摘要

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