Research On Decision Optimization Of Remanufacturing Closed-loop Supply Chain Under Information Asymmetry

The traditional economic development model consumes a large amount of natural resources.With the aggravation of resource shortage and rapid product replacement caused by technological innovation and progress,the society has begun to turn to the closed-loop supply chain(CLSC)model of sustainable development in recent years.Different from the traditional supply chain,the coordination of CLSC is more difficult due to the instability of remanufacturing product quality,recycling rate and uncertainty of market demand.In addition,there is a serious problem of information asymmetry in the closed-loop supply chain,which to a large extent hinders the coordination and remanufacturing decision optimization.Therefore,in the CLSC with information asymmetry,this study introduces the quality information disclosure strategy and demand information sharing strategy to figure out the harm caused by information asymmetry,and considers how the quality preference of consumers under different quality information disclosure mechanisms affects the decision-making optimization of manufacturers and retailers.Most of the existing literature only considers information sharing strategy in forward supply chain.Existing researches mostly ignore how manufacturers and retailers in the closed-loop supply chain should use their information advantages to optimize recycling and pricing decisions under information asymmetry.However,it is necessary to study the intersection of information disclosure strategy and remanufacturing in closed-loop supply chain.Therefore,this study investigates how the quality information disclosure mechanism and demand information sharing decision influence the optimization of decisions in a remanufacturing CLSC with asymmetric information.Based on this,this study takes game theory as the research method and uses mathematical modeling and other methods to optimize the quality information disclosure mechanism,demand information sharing strategy,pricing decision and recycling decision in the information asymmetry closed-loop supply chain.This study makes several contributions:(1)By combining the quality information disclosure decision with the remanufacturing model,the influences of the disclosure of product quality information by manufacturers on the pricing and recycling decisions in the CLSC under the two disclosure strategies are compared.(2)We integrate demand information disclosure into a remanufacturing model and assess the impact of recycling competition and information disclosure decisions on pricing and recycling decisions under different channel power structures in the CLSC.To our knowledge,this is one of the earlier studies that combine information demand disclosure with recycling competition and channel power structure in the CLSC.(3)We extend the study of information disclosure decision on remanufactured product yield decision.We study how the manufacturer’s information disclosure strategy influences output decisions for new product and remanufactured product in the case of new product and remanufactured product are heterogeneity.
