Auto Fast-repair Chain Layout Optimization Based On Influence Of Nodes

In recent years,the gradual saturation of the current automobile front-end market has aroused attention and development to the auto after-sale market.As for after-sale market,fast repair chain has a good development prospect.How to pinpoint the location of car fast repair chain has become one of the most important things in this area.This article analyzes the domestic automobile chain industry’s present situation,combined with investigations and analysis on the factors affecting the layout of auto-repair chain,and sort out the relevant theories and research methods,so as to provide some reference for the development of domestic automobile fast repair chain industry.At first,this paper introduces the development of automobile fast repair chain at home and abroad,and investigates and tidies up the factors which should be considered when setting up new car fast repair chain.And Analytic Hierarchy Process is used to determine the weight of each factor.And by reading other similar literature,the concept “influence” is presented.And based on this concept,the first step of filtrating is done.Based on research and analysis on optimization model of common locating problems,the object annual profit of fast-repair chain is set,and the constraint is fixed investment.After modeling,Genetic Algorithm is used to calculate the final results.By modifying the constraint,another result can be obtained.Compare these two results,the reliability model has been proved.According to the research mentioned above,this paper takes Dalian city as example,and the research area includes the downtown area,which excludes Lvshunkou Area,Pulandian Area,Jinzhou Area.Through analyzing and calculating the data of Dalian,we can get the final results,which are the locations of the fast-repair chain.This can provide some guiding significance for the development of fast-repair chain in our country.
