Closed-Loop Supply Chain Of Three Recovery Modes Under Demand Disturbance

With the continuous development of social economy,the increasing concern of the environment,recycling as a way to improve social benefits and reduce the development of environmental resources,has been more and more people to explore and use.And the rapid development of the market reverse logistics,recycling and economic benefits and benefits have become a social development can not be ignored in the link,choose a reasonable market development in line with the recovery of the whole society has a very positive impact on the sustainable development.In view of this,based on the current domestic and foreign research,using the comparative analysis method,case analysis method,literature review method and game analysis method,through the establishment of the game model,for manufacturers,retailers,consumers And how to make the optimal distribution of the interests of the parties in the case of market demand disturbance,and compare the optimal decision of the members in the closed-loop supply chain under the three recovery modes.By investigating the demand of the market,Closed-loop supply chain is adjusted to suit the market development model.The main contents of the thesis include:(1)This paper discusses the optimal decision of the closed-loop supply chain,which is only involved in the recovery of the market demand by the manufacturer:The optimal decision model of the closed-loop supply chain composed of the single participant in the complete information sharing and the two competing retailers who are not involved in the recovery is set up under the market demand disturbance,the optimal decision of the parameters in the supply chain under stable scenarios and perturbations is discussed.Through numerical calculation,graphic analysis,comparative comparison,the following conclusions:The occurrence of emergencies,retailers and manufacturers tend to adjust the retail price and wholesale price in the direction of perturbation changes to ensure the optimal profitability of the supply chain;When the demand disturbance is within a certain threshold,the manufacturer's production and recovery rates are also robust.(2)The optimal decision of closed-loop supply chain with individual retailer involved in recycling is discussed when the market demand is disturbed:The optimal decision model of closed-loop supply chain composed of individual manufacturers with complete information sharing and two competing retailers(one participant in recovery and one non-participation)is constructed.Through comparative studies,retailers involved in.recycling can expand their market share faster in the perturbed scenario,gain more profits,and be more competitive in the marketplace;The greater the market demand,the more conducive to the recycling of waste products,both to allow consumers to obtain concessions,but also re-use to reduce costs,so that consumers and the entire supply chain to achieve a win-win.(3)This paper discusses the emergency decision of two retailers involved in the recovery of closed-loop supply chain under demand disturbance:The optimal decision model of closed-loop supply chain composed of individual manufacturers with complete information sharing and two competing retailers involved in recycling is given under the market demand disturbance,the optimal decision of the parameters in the supply chain under stable scenarios and perturbations is discussed;Through comparative study,when the demand for positive perturbation,the manufacturer,the retailer will be based on perturbation to adjust the strategy;When the demand is negative,the manufacturer is willing to consider the disturbance to adjust the decision,but the retailer's decision under the disturbance and the original stability of the decision-making change littleThe analysis and comparison of the above three recovery models leads to a closed-loop supply chain model in which manufacturers are involved in recycling and a closed-loop supply chain model in which two retailers are involved in recovery to meet the requirements of a stable development of the manufacturer's business,closed-loop supply chain models for individual retailers involved in recovery ensure retail and consumer market boom.So the government can be based on local development needs,targeted to give recycling subsidies to guide the closure of the supply chain to adapt to local development.
