Studies On Locating The Reverse Logistics Center And Optimizing The Transportation Network In The Product-Recovery Network

There is a new area on reverse logistics. In 1980s, the word of reverse logistics appeared in an overseas journal. In the early of 1990s, reverse logistics is beginning to be widely concerned by some developed countries as the governments and consumers are more concerned about environment. China has paid much attention to forward logistics, but there is little concern on reverse logistics.The thesis address the reverse logistics based on which the paper researches the product-recovery network programming. The first part introduce the actuality, conception and the operation of reverse logistics, then discuss the product-recovery network.It is important to choose the optimized transportation courses and the right location of the reverse logistics disposal center because the price of the recovered product is generally low and the related cost of transporting and processing is very high.The thesis set up a product-recovery network model and a model considered the time limits which based on the studies of reverse logistics and use the improved algorithm based on the algorithm for finding the minimum spanning...
