Research on Simulation Based Dynamic Scheduling Strategy of the Logistics Distribution System for Assembly Lines in Engineering Machinery

Abstract

Abstract The objective of designing a logistics system for assembly production planning should be accurate, efficient distribution, and low cost. It is difficult to use mathematical methods to solve the design of logistics distribution route planning for a given layout of assembly lines which often be restricted. We take the logistics distribution system for actual assembly lines of engineering machinery as the research object, and analyze its current status. And we build a 3D simulation model of the corresponding scene, and use a variety of logistics scheduling methods to optimize the logistics distribution system. Considering the congestion strategy characteristics of some distribution channels, adjustment strategy of time window is proposed, and a dynamic scheduling strategy of congestion is designed. Combined with the simulation tests, we analyze and optimize the solution suitable for the actual assembly lines. The results show that our strategy had better performance than other common scheduling strategies. And the proposed strategy could optimize the material distribution system of assembly lines, reduced the number of vehicles and the cost of the enterprise.
