Abstract
With the rise of environmental awareness in recent year, reverse supply chain has been given great attention and concerns. Manufacturers not only care about investment in development of product quality, but also to note the condition of products after use. Including service or product recycle are very important issues, all of these reasons let reverse logistics become the important research topic gradually. In the past, efficiency and cost often considered as the first priority for reverse supply chain system design. But forget to consider the product value of time, ignore the significant value inside. Then the system design for speed of responsive has been development, enterprises can explore the value inside and make profit. The purpose of this research is to optimal reverse supply chain system design by considering marginal value of time and product restock rate.
First, we refer to the past literatures about reverse supply chain system design. Then build a dynamic programming model under situation of product value, market demand and new return rate decline with time to optimize manufacturers’ system choice and quantity of manufacture. Inside the objective profit functions of each scenario, produce cost, repackage cost, additional cost, handling cost, transportation cost, inventory cost and shortage cost are taken into account. In order to maximize profit for the manufacturer to solve the objective function.
Finally, numerical analysis is done. According to the results of sensitive analysis, we discuss the impact of parameters changing and have some advice to manufacturer for system choice. The results reveal that when product value decline rate and new return rate decline rate are low, “postponement” system is the best choice; And conversely, when both are high, manufacturers should choose “preponement” reverse supply chain system.
