The Research Of Supply Chain Coordinating Base On Collection Pricing

With the development of society and the advance of science as well as technology, both the amount and the variety of industrial products has been increasing rapidly, which accelerates the resource consumption and intensifies the environmental problems, and causes numerous other issues. Thus, the existence of human kind even has been threatened. How to turn the "waste" into the "treasure" and to recycle wasted products have become hot issues of common concern, for the sake of alleviating resource consumption and environmental pollution. Recycling and remanufacturing wasted products conform to the needs of social development, consequently, the reverse supply chain management also becomes the hot issue of public concern now.The reverse supply chain is made up of several relatively independent enterprises or different departments in the same enterprise. For the reason that members of the reverse supply chain will maximize their own profit, thus double marginalization appears and the reverse supply chain then will be inefficient. The coordination of reverse supply chain can improve its efficiency, bring more profit for enterprise remanufacturing, and provide a channel for recycling social resources to relieve pressure on the environment. Therefore, the coordination problems in the reverse supply chain have important theoretical and practical significance.Firstly, this paper studies the circumstances when the manufacturer only recycles the products that fit the remanufacturing requirements recovered from collectors, and the detection cost is ignored. This paper considers that the collection quantity is a linear function of collection price and the influence of collection effort to the collection quantity, attempting to construct the pricing model of recycling and to optimize it, and compares the independent decision model with the joint decision model between the manufacturer and collector. The revenue-cost sharing contract is then used to coordinate the reverse supply chain. Secondly, this paper considers the manufacturer's buyback of all wasted products recovered by collector, then the detection of the wasted products and the payment. As the wasted products don't fit the remanufacturing requirements, the recycle salvage value collection is considered. This paper compares the system efficiency of the independent model with the joint model between the manufacturer and the collector, and then uses the revenue-cost sharing contract to coordinate the reverse supply chain. The numerical example is also given for analysis.
