Research Of The Optimization Of Production Enterprise Logistics System Of A Auto Parts Based On The Lean Theory

With the rapid development of society and technology, consumers’ demands for personalized goods become more and more prominent. The traditional single specie’s mass production is gradually emerging in the new situation. Enterprises’ manufacturing scale and the mode of production is gradually turning into the many varieties of small batch. The change of production mode has brought great challenges to the manufacturing enterprise workshop production. As an important part of the production process, whether the workshop logistics system’s operation is efficiency or not has a very great effect the efficiency of production. In this background, this article is based on the lean theory, analyzes the present situation of the logistics system of A enterprises, and puts forward the existing problems and the optimization scheme in view of the current situation of logistics system.As A auto spare parts production enterprise as the research object, firstly, this article introduces the theory and method of lean logistics, mainly discusses the basic concept, ideological characteristics and requirements of manufacturing enterprise lean logistics and the main methods and tools of lean logistics. Secondly, the paper introduces the overall situation of auto parts manufacturing enterprises as A enterprise an example, analyzes the the current situation of logistics system of the enterprise emphatically, and points out the existed problems of A enterprise’s logistics system including the instability of the production plan, unreasonable production layout and low logistics distribution rate. Then this paper proposes the optimization scheme on the basis of the A enterprise logistics system.The optimized scheme mainly starts from the optimization of the layout of production line and the design of internal logistics rhythm. The former is based on Flexsim simulation software and build the simulation model of A enterprise workshop production line layout, find the main bottleneck of this production line through enough time simulation unit and optimization and improvement; through customer orders for reliability analysis of A business(COR), the latter mainly design a much more reasonable internal logistics to ensure the enterprise internal logistics activities more on time.Finally, based on correlation matrix method, this paper evaluates the result of optimization scheme of the logistics system and confirms the effectiveness of the proposed scheme. In the conclusion part, this paper summarizes the main research work and achievements, and points out the insufficiency of this dissertation and needs further research.
