Closed-loop Supply Chain Optimal Decision And Coordination Research Based On Mean-cva R

The core of closed-loop supply chain summed up the product’s delivered with reverse recycling, the formation of "resources- production- consumption- renewable resources" of the closed-loop feedback loop process, which requires the closed-loop supply chain node enterprise cooperation, promote each other. But the traditional closed loop supply chain management, which are based on self-interest maximization as the goal of independent decision-making, which considering the node enterprise’s preferences, so you can’t make the closed-loop supply chain to achieve pareto optimality. Therefore, we design the revenue sharing-cost sharing contract link in the enterprise of the closed-loop supply chain system, we realize enterprise and society environmental protection a win-win situation. The preferences of nodal enterprises is a great impact on the enterprise of decisions and profits, This is also a big problem with closed-loop supply chain management.Therefore, in this paper, we further study the risk neutral and based on the mean-CVaR metrics under different risk aversion,the main contents are as follows:(1)When the node enterprises is risk neutral, by using mathematical model studied each node enterprise optimal decision and profit level under centralized decision-making and decentralized decision-making, we get the sales of decentralized decision-making and scrap prices are less than the sales of joint decisions, which leads to the profits of retailers, manufacturers and recyclers, did not achieve the optimal, the closed-loop supply chain system did not achieve the pareto optimality. Then we design the revenue sharing-cost sharing contract perfect coordination of the closed-loop supply chain, and we find out the revenue sharing factor and cost sharing factor value range.(2)The paper by mean- CVaR metric construct the mathematical model,which studied a three-stage closed-loop supply chain system with a risk-aversion retailer, a risk-neutral manufacturer and a risk-neutral recycler, the optimal decision of the closed-loop supply chain members are analyzed in decentralized decision and joint decision. We prove that the mean-CVaR measurement criteria can improve more order quantity and profits than the CVaR for the retailer. The research shows that revenue sharing and cost sharing contract not only can accomplish closed-loop supply chain coordination, but also can improve the recycled waste products on mean- CVaR measurement principles.(3) When retailers, manufacturers and third party recycling agent are risk aversions, By the mean-CVaR theory building the mathematical model, we analyzed the optimal decision and profit levels of each node enterprise. we studied, under certain conditions, the improved revenue sharing- cost sharing contract can coordinate the closed-loop supply chain system of risk aversion after using the mean- enterprise risk CVaR measurement.
