Network node’s dynamical location of remanufacturing reverse logistics under uncertain environment

Network node\´s location of reverse logistics becomes the foundation and prerequisite of high-quality operation of reverse logistics system, according to the quantity uncertainty of recovery products and the changing demands of remanufacturing "new" products, furthermore as time goes on the modes of its cost and income will alter, so we need to confirm a time-varying dynamical model of location. From the perspective of manufacturing enterprise, as former models didn\´t consider the combining elements of the changing time, the quantity of recovery products and the demands of "new" products. Therefore this text firstly forecasts the amount of recovery products and the demand with the use of time series flat method, introduces the predicted correct factor to raising the accuracy, then draws the conclusion using the static modal of location and utilizes the dynamic programming technology to find out a location formula of two-way logistics\´ sharing transport network with the target of maximizing accumulated total current profit of manufactory enterprise during the planning period.
