Simulation and optimization about sorting system of distribution center

New areas of modern logistics research focus on the direction of three-dimensional simulation technology, mainly about the method of logistics simulation modeling and the technology of logistics simulation implementation. Based on in-depth study of the principle of sorting system, this paper used three-dimensional simulation software Flexsim to have realized the system design, simulation modeling, simulation run, data analysis and system optimization of two sorting modes of distribution center: picking style sorting system and seeding-type sorting system, then verified the validity, rationality and optimization of the simulation sorting system, showed the advantages and disadvantages of two sorting modes clearly, which have important reference value to the sorting system development and improvement of enterprise and the applications of Flexsim simulation software in logistics fields.
