Research On Optimization Of Dynamic Battery Reverse Logistics Network

With the improvement of living standards,automobile penetration rate is getting higher and higher,and the oil consumption also increases year by year.At the same time,the environmental pollution caused by the massive discharge of pollutants is also getting worse.Meanwhile EVs use electric energy as the power source,reducing the urban pollutants.With the improvement and upgrading of electric vehicle technology,EVs can gradually meet the needs of people's daily short-range traffic.Consumers are beginning to accept electric vehicles.At the same time,the issue of power battery recycling becomes prominent.Whether it is manufacturers,enterprises or environmental organizations,the research on the recovery of power batteries is relatively weak.In china,I found that scholars in various research fields do research on reverse logistics network from the perspectives of industry,third-party recycling and social responsibility when doing researches on network design and node selection of power battery.These methods are provides a reference to the battery recovery,but did not take into account of that part of the battery after a simple maintenance will be able to meet the needs of energy storage center reuse,this recycling can make full use of natural resources.This article consider this perspective,starting collect battery from consumers,scrap metal recycling center and energy storage center as the destination for the design of reverse logistics network.According to the idea of this article,the main work has been done as following points:First,studied the power battery and its related literature to understand the characteristics of the battery,especially the power battery which contains the precious metal species can be reused,that is a theoretical foreshadowing for the following reverse logistics Network nodes and recovery methods.Secondly,the existing design methods and design principles of reverse logistics network,common node location theory and transportation optimization model are studied,and the model basis is established for the design and transportation optimization of reverse logistics network node of power battery.Thirdly,on the basis of the above two,this paper designs a reverse logistics network that is in accordance with the power battery,and also plans the node location of the regional library and the optimal transportation volume of the transportation.The heuristic algorithm is used to realize the location selection of the regional library The work first determines the location of the regional library in a certain area and uses PSO algorithm to optimize the traffic volume.Fourthly,based on the design of reverse logistics network,a region is selected according to the model and calculation method selected in this paper.The network and algorithm proposed in this paper are calculated and the model of network node selection and transportation quantity optimization Effectiveness.
