Design And Application Of The Simulation Platformof High-Speed Sorting System

Sorting is one of the three core operations which include storage, sorting and delivery in the distribution center. The full-automatic high-speed sorting system and its efficiency become the key factor to improve the efficiency of the whole distribution center.At present, the research of the full-automatic high-speed sorting system and related technology shows diversification. Different order structures, sorting modes, combinative modes of the equipments, work patterns and efficiency of the single equipment can all influence the efficiency of the whole sorting system. How to study the sorting efficiency, improve the sorting efficiency, eliminate the bottleneck become the key factors of restricting the development of the full-automatic high-speed sorting system. So, the theory field and engineering application field pay more and more attention to the full-automatic high-speed sorting system and the full-automatic high-speed sorting technology.This thesis aims at structuring the simulation platform of the full-automatic high-speed sorting system, analyzing the dynamic changes of the sorting efficiency and finding the bottleneck of the sorting system. Through improving the sorting methods, such as sorting modes and combinative modes of the equipments enable the sorting efficiency to reach maximum.This simulation platform makes a tobacco distribution center as the prototype, utilizes the object-oriented Petri net(OOPN) to set up the order dealing model, the replenishment model and the sorting model, describes the dynamic procedure of the order dealing system, the replenishment system and the sorting system. On this basis, this thesis develops the simulation platform of the full-automatic high-speed sorting system based on the OOP technology and the OpenGL technology which improves the view and authenticity of the full-automatic high-speed sorting system and is convenient to analyze the cause of the bottlenecks.The verification to the simulation platform with the true sorting order data of a tobacco distribution center shows that the sorting efficiency is in conformity with real data of the spot sorting system, which proves the validity and the practicability of the simulation platform of the full-automatic high-speed sorting system.Based on the application of the simulation platform in this thesis, this simulation platform can not only verifies the rationality of design plan and optimize of the full-automatic high-speed sorting system, but also offers effective support to the research of the technology and the theory of the full-automatic high-speed sorting system. Meanwhile, the simulation platform accelerates the designing procedure of the full-automatic high-speed sorting system.
