Research On Models Of Reverse Logistics Distribution Routing In Green Logistics System

In recent years, along with the continuous scarce resources, and the increasingly serious environmental problems, people pay more attention on resources and environment problems. Because of the reverse logistics play an important role in the conservation of resources and effectively control pollution by recycling waste items and utilization, experts and scholars, business pay more and more attention to it. The core of reverse logistics is transport, so how to effectively configuration recycle vehicles and choose reasonable path to reduce the reverse logistics transportation cost is the key. Because of the demand dispersion and the occurrence time, place, volume, weight and other characteristics of the reverse logistics are uncertain; make the vehicle configuration of reverse logistics more complexity compared with the logistics distribution particularity. And path towards and more, so need to based on the characteristics of reverse logistics to research the theory,the model and the method of the configuration of the vehicles and optimization of the path.This paper first summarize the current research status of reverse logistics distribution path model, focus on the core idea, operation mode and their advantages and disadvantages of several different distribution model.Mainly makes a detailed introduction of the characteristics and produce of the VRPB, VRPDP model among them. Secondly, based on circular economy, green logistics and reverse logistics puts forward the concepts of degree of distribution priority according to time sensitive type recycling product and build the reverse logistics distribution path model with a limit coefficient. Finally, through the analysis of the example that this paper further shows the reverse logistics distribution path model to show the effect of it on recovering the product in effective repeat use, reducing logistics cost, improving the enterprise economic benefit.This paper is based on the circulation economic theory, green logistics theory, and reverse logistics distribution path theory, to construct the reverse logistics distribution path model. The prominence of this model is adding the distribution of the priority variable, to enrich and perfect the existing reverse logistics. Distribution path model and will play an important role in enterprises to reverse logistics development and practice. Therefore, this paper not only has a certain academic value, but also an important economic value.
