Research On The Cost Control Of Automobile Parts Supply Logistics Based On Milk Run System

Since the recovery of the financial crisis,the automobile industry in China to flourish,automobile production and marketing has been reelected for eight consecutive years in the world at the same time the industry competition is also increasing.In order to obtain a competitive advantage,expand the profit margins,automobile manufacturers have been aimed at the parts into the logistics of the production and supply of key links in the cost control aspects.In this paper,the automobile manufacturing enterprises in the emphasis on lean production,under the conditions of supply under the conditions of parts and components into the logistics often high cost for the research background to the existing research results and business practices at home and abroad,the key to the cycle of distribution Plant logistics model for a comprehensive,systematic research.For the needs of small quantities,high frequency of auto parts,the use of circular distribution to pick up delivery,can not guarantee the timely supply of spare parts to meet the needs of lean production,but also effective control of the stock,but also as a substantial Increase transportation costs.Compared to the traditional way of direct delivery,both the cost of transport or inventory costs can be substantially saved.However,due to the large number of auto parts,the number of large,into the factory to coordinate the operation requires high characteristics,the application of circular distribution model of the automobile enterprises often can not achieve the desired application effect.Therefore,how to combine the service of the automobile manufacturing factory and the professional third party logistics company based on the reality of our country,it is a very important research content to optimize the logistics flow by the circular distribution mode and finally reduce the logistics cost.This paper first summarizes the main problems of the current domestic auto parts circulation and distribution logistics operation,summarizes the relevant theory,and puts forward the key to the cost control of the incoming logistics in the circular distribution mode.How to optimize the line edge inventory and parts on the assembly line Supply of vehicle distribution program.And on this basis,the cycle of distribution to optimize the way into the logistics of the implementation of the conditions,operational processes,planning and design to make a comprehensive exposition.Secondly,for the problem of the route planning of the cycle picking vehicle,aiming at the characteristics of the demand of the parts for the automobile factory,it is put forward that the maximum inventory constraint should be set,the parts of the plant should be set to the smoothing of the equipment,and the vehicle path planning model,Which has become the biggest innovation of this article.According to the characteristics of genetic algorithm with multi-objective optimization effect,the genetic algorithm for the problem itself is designed.The feasibility of genetic algorithm is verified by stochastic data simulation and the function between total cost and maximum inventory is obtained Relationship lines.Finally,according to the operation problem of H company’s incoming logistics,this paper proposes to solve the problem by using the optimization model of circular distribution,and use the relevant theory of cyclic distribution model,the mathematical model and the genetic algorithm to design the practical problem to plan A good effect.The purpose of this paper is to provide an effective reference method for the logistics practice of the automobile manufacturing industry by means of the qualitative and quantitative analysis of the cyclic distribution of auto parts,and the effective optimization method to control the logistics cost.
