The Study On Optimization Of A Distribution Center

Since the 1990 s,with the global economic and trade and the development of national economy,logistics has been in this line to promote the development of a country's economic backbone,to boost the country's international competitiveness and overall strength are playing an increasingly important role,the development of logistics enterprises is very significant meaning.Logistics enterprises to develop,to gain higher yields,the distribution center can begin to establish a fast and efficient logistics operation system,from the commodity procurement,production,transportation and warehousing to the sales of the whole supply chain link cost savings,implement open source throttling.Distribution center is to accept and deal with the end user of the ordering information,for many varieties of the goods from the upstream sorting,according to customer's orders for the work,such as picking,processing,equipping and delivery of facilities and institutions.Distribution center within reasonable layout and efficient operation,is one of the important link to improve the market competitiveness of enterprises,which reduce the response time and reduce the storage cost,improve logistics service level is crucial.This paper studies the optimization problem of distribution center,first elaborates the research background and research significance of the cargo location optimization of the distribution center,and introduces relevant theoretical knowledge.Then to B company supply chain under the module of A distribution center as the background,the investigation and analysis of the status quo of A distribution center layout and management status,mainly for the "double A" big promotion in 2017 broke problem investigation and study,from A distribution center harvest timely rate,timely receipt rate,delivery success rate,damage rate and loss rate of five indicators,analyzing the cause of A big drop in the key analysis harvest timely rate in time,after analyzing harvest timely rate in time because of lower during the "double A" find A distribution center of goods allocation methods affect the operating efficiency,its allocation method is still belong to according to the experience of the staff would be distributing the position of the traditional way.Then,this paper,based on the traditional position of A distribution center allocation method in "double A" bigpromote broke in question and on the basis of the improvement,from A distribution center position within the allocation and the way of picking part of goods have chosen to study,the optimal placement rule based on the goods,picking part minimum energy consumption as well as the shortest,the optimal picking tour the three indexes to establish A multi-objective optimization model of distribution center,and to solve the generation into the data.Finally,according to the results concluded that: A distribution center of most goods store goods is not the best location,A distribution center of goods in the wake of optimized allocation can improve its working efficiency,and saves the manpower,ease the large promotion period problem caused by blasting storehouse,the other distribution center to improve the B company during the large-scale promotion of operational efficiency have certain reference significance.In a word,it is of great significance to improve the logistics operation efficiency of distribution center by carrying out the optimization of cargo space to reduce the explosion of the distribution center in the case of large-scale promotion.
