Optimal Decision Of Closed-loop Supply Chain With Dual-recycling Channels

In recent years,the recycling and remanufacturing of products by enterprises has become a hot issue in production practice.Remanufacturing can alleviate environmental pressures,reduce waste of resources,promote economic development,improve company profits and reshape the company's image to a certain extent,which has caused closed-loop supply chain management to attract widespread attention.In addition,with the development of economic globalization,the supply chain is also globalizing,and companies have deployed overseas supply chains to make the supply chain more and more complicated.The inherent vulnerability of this huge system containing countless nodes is also obvious.Disruptions caused by supply disruptions can have widespread negative effects.However,in recent years,the frequency of emergencies has become higher and higher,and the probability and impact of supply disruptions will also increase.As a result,there are more and more studies on closed-loop supply chains and supply disruptions,but few studies have focused on the impact of supplier disruption risks on closed-loop supply chains based on mixed recycling channels.Disruption has a greater impact on the supply chain.Based on this,this paper studies the optimal decision of a closed-loop supply chain with mixed recovery channels under the risk of supplier disruption.Firstly,the closed-loop supply chain optimal model with dual-recycling channels under the consideration of supplier interruption risk based on linear demand.Among them,the supply chain members include a manufacturer,a retailer,and a third-party recycler.This article assumes that there are two raw material suppliers,of which the main supplier may have a supply interruption,but the price of the raw material is relatively cheap,and the backup supplier does not occur,but the raw material price is relatively high.Establish a Stackelberg game model in each of the three mixed recovery models,and establish the optimal recovery price,the optimal wholesale price,the optimal sales price,and the optimal order quantity for each model in the case of decentralized decision making,and then analyze these optimal values The relationship with the probability of interruption and an empirical analysis of the model through numerical examples.Then,the linear demand is turned into a stochastic demand,and the retailer considers the cost of holding the product and the cost of stock out to be considered in the model.Finally,based on the results of theoretical and numerical examples,by verifying the relationship between the supplier's outage probability and the optimal decision of a closed-loop supply chain with dual-recycling channels,the main conclusions of this article are summarized,hoping to give corporate managers a certain References to enable them to make sound decisions in the face of supply disruption risks.
