A Multi-Objective Optimization Model Design On The Terminal Distribution Network Of E-Commerce Logistics

At present,the domestic E-commerce business and sales continue to rise,and the consumers have the more stringent requirements about the logistics distribution on the timeliness and economics.In particular of the terminal distribution network of E-commerce logistics,because it has a direct impact on consumers evaluation of the distribution process consumer experience.Although the distribution speed has been greatly improved in recent years,in some special holidays such as "double eleven",the distribution of the timeliness can not be met,often appear receipt delay.Therefore,the terminal distribution network of E-commerce logistics needs to be further optimized in the protection of its economy,at the same time,should paying attention to the network survivability to guarantee the stable development of the E-commerce business.Through the analysis of terminal distribution network of e-commerce Logistics based on the analysis of the status of the terminal distribution network of E-commerce logistics,and the theory of distribution network,multi-objective optimization theory and network survivability theory,the impact of economic costs and the network survivability to the optimization of the terminal distribution network has been cleared.On the basis of this,the multi-objective optimization model has been established.Meanwhile,the optimization model of the least economic cost and the highest survivability of the network is built,The conclusion shows that the optimization goal of introducing the survivability is more reasonable to the optimization of the logistics distribution network and guarantee its stability.Simulation analysis also validates this conclusion.Based on the above qualitative and quantitative analysis,a reasonable scheme of optimization of the terminal distribution network of E-commerce logistics is proposed.On the basis of the economic cost optimization of the network,the new goal of network survivability was introduced to optimize the terminal distribution network,and the change of the network stability was analyzed.With the change of the network survivability,cost changes.And finally the model reached a certain degree of balance between the two,to find the most satisfied with the optimization program and to protect the rapid development of electricity industry.
