Study On The Location Of B2C Electronic Commerce Reverse Logistics Center Based On Genetic Algorithms

In recent years,with the rise and development of B2 C e-commerce,e-commerce sales model has gradually replaced the traditional sales model.This means to carry out Internet online sales activities providing a convenient and efficient service for the people.On the other hand,because of the differences between virtual it,customers in the purchase of goods during the period of hope and reality is very easy to cause the reverse logistics,namely return logistics.With the popularity of B2 C e-commerce,the reverse logistics is increasing.It will make the burden of enterprises more and more serious and it will also make resources unreasonable and wasteful.However,these do not make use of the economic and social development of the enterprise.Because of this,the reasonable planning of reverse logistics under the B2 C e-commerce mode has been paid unprecedented attention.Scientific and reasonable reverse logistics will create great value for enterprises and society.For B2 C e-commerce enterprises,facing the phenomenon of increasing returns,solving the problem of reverse logistics has become a top priority to reduce transportation costs,reduce logistics costs and improve user satisfaction.First of all,this paper studies the related theories of activity cost analysis.Reverse logistics network and reverse logistics center location in the optimization of reverse logistics center.Secondly,we analyze the existing straw recovery logistics network from four aspects including resource characteristics,location of reverse logistics center and location optimization.Through the analysis of reverse logistics,new items with non vulnerable characteristics is caused by e-commerce enterprises mainly due to the high cost of B2 C e-commerce.Reverse logistics network including customer returns,reverse logistics center.Purchase of new customers and other logistics nodes and transport routes.Reverse logistics center in China the two layer network structure.With little regard to the reverse logistics of goods processed or processed by the goods,so you need to optimize e-commerce.Reverse logistics center location including main contents of reverse logistics center,logistics center,analysis to determine and develop new alternative selected transport scheme etc...Then build the optimization model of reverse logistics network layout including the determination of the minimum cost model of target one by one and the best service.From the perspective of specific work division and reverse logistics center hidden cost analysis of reverse logistics cost in e-commerce enterprises.To constitute the transportation cost,operation cost,fixed cost three parts from the lowest return to customers reverse logistics and reverse logistics cost and from the center to the new customers for the lowest cost goal of the construction of reverse logistics center optimization model of double.Finally,a numerical example is given to prove that the double layer programming model and the genetic algorithm can optimize the location of the reverse logistics center of e-commerce enterprises.
