Research On Quality Control Strategy Of Waste Products In Closed-loop Supply Chain

The closed-loop supply chain consists of manufacturers,retailers,second-hand businesses,reprocessing centers and raw material market.Due to the unstable level of quality of waste products,remanufacturing can result in a situation where manufacturers' expect benefits decline.At this point,manufacturers need to control the quality level of waster products,and improve the quality of waste products that participate in remanufacturing through quality control.This article takes the quality control of waste products as the research object.And focuses on the quality control standards of waste products,which discusses the impact on the cost input and sales price decision of each participant in the closed-loop supply chain.There are three types of incomplete replacement products that exist at the same time as the market sales competition relationship.Analyses take place in two different backgrounds: the quality of used products is random or controllable.First of all,under the background of the random quality level of used products,the decision-making changes brought about by retailers and manufacturers' relationship of cooperation/game are discussed separately.When the retailer cooperates with the manufacturer,sampling inspection cannot improve the quality level of waste products.Once the quality level of used products reaches a certain level,manufacturers will choose to receive all recovered waste products for remanufacturing,otherwise they will not plan the remanufactured production..At this point,the pre-examination concept is introduced to obtain the optimal quality detection time node.When retailers and manufacturers play together,due to the existence of quality inspections,retailers bear the risk of uncertain quality levels and obtain the optimal quality inspection standards.At this time,it should be accompanied by a certain recovery incentive to ensure that retailers do not abandon recycling because they assume the quality risk of used products.Secondly,under the background of the controllable quality level of waste products,the decision-making changes caused by cooperation/game between retailers and manufacturers are studied.When the retailer cooperates with the manufacturer,we get the best quality level of waste product.In the game between the two,retailers change the quality level of discarded products by controlling the cost of quality inputs.Manufacturers make retailers make decisions that meet their own interests by establishing testing standards.Finally,the conclusions are verified by examples,and the parameters are converted into actual data by analyzing the images of the examples.Establish links with actual production,and provide guidance for decision-making of participants in the closed-loop supply chain.
