Research On The Optimization Of Storage Positions For Auto Repair Parts

With the rapid economic development,Chinese logistics costs as a proportion of GDP in 2015 is still close to 16%,and the United States earlier to 7.85%,so,compared with developed countries,there is still a lot of room for optimization of logistics cost in China.Among them,the transportation costs,storage costs,management fees of total logistics costs is 53%,35% and 12%,respectively.So you can start from the transport or storage of the optimized logistics cost,this storage optimization.Economic development has also led to the development of the automobile industry,as of 2015,civilian car ownership in China is about 172.28 million and 10% per cent of the rate of increase in growth.According to statistics,the after-sales service costs the price of a vehicle twice.Car service also known as the automotive aftermarket,car market has huge profits,including maintenance costs account for the aftermarket value chain 40%.Automotive has a wide range of spare parts required for maintenance,weight,value differences,a strong correlation,risk characteristics,resulting in auto parts keep difficult,increased storage costs.In this context,this research on automobile parts warehousing,concrete research shelf optimization problems.Through an in-depth analysis of the characteristics of auto parts was established with the goal of picking minimum total cost optimization model for location,and taking into account the weight of the goods,characteristic value,relevance of the three factors.A case study of a company vehicle repair parts storage to validate the model.This research of main content is:(1)description this papers of research background and the meaning,through on both at home and abroad logistics cost of data,and car spare parts industry of data,and China motor vehicle maintenance costs of data for compared analysis,obtained research vehicles maintenance parts warehouse management optimization of need,main on its shelf optimization problem for research;then on warehouse shelf optimization problem of related research and the related theory for summary,determine has this papers Research of research direction.(2)Automotive parts analysis,select a wide range of auto parts,a strong correlation,value differences,differences in weight and risk five characteristics were analyzed.(3)Parts shelf optimization model of first analysis summarizes the general location model;and then to analyze the five characteristics of automotive spare parts,summed up the objective: to target a minimum total cost under the premise of considering parts of weight,value and relevance of the three characteristics.Which,weight of features,is from weight will increased take goods cost,and weight on shelf of effect two aspects consider of,established has b work minimum for target of model and while consider shelf of gravity problem;value is from take goods risk consider of,for value big of parts,put have more far,take goods risk more big,so established has to take goods expects loss minimum for target of model;parts of correlation decided has has correlation of parts of placed seat,So established a correlation between parts placed no closer than a certain distance constraints.Finally convert the work value loss,pickup and expected loss constitutes a pickup ultimate cost model.(4)In a company vehicle maintenance spare parts warehouse location optimization,for example,the actual data is a company vehicle maintenance and spare parts warehouse: shelf width,length,number of pickup parts weight,frequency,price and other parameters into the chapter of the location optimization model.Converts a model into the LINGO language,LINGO software running the solution,and the results were analyzed,goods consumption reduces the total cost of 503.1,get 14.03% ratio and makes heavy parts placed on the shelves of low-rise,laying distance of relevance.
