废弃食用油逆向供应链最优契约模型研究

Research on Optimized Contract Models of Waste Cooking Oil Reverse Supply Chain

摘要: 本文基于第三方物流回收模式，建立两级废弃食用油供应链模型，包含一个生物柴油制造商和一个废弃食用油第三方回收商，利用博弈理论设计了两种供应链契约模型(非合作博弈与合作博弈)，通过对两种供应链契约模型进行比较，得出合作博弈下回收数量和系统利润较高的结论。

Abstract: Based on third party logistics collecting model, a two-level waste cooking oil reverse supply chain (RSC) model involving one biodiesel manufacturer and one third party logistics collector is devel-oped. Optimized supply chain contract models (non-cooperative game and cooperative game) are proposed by employing game theory. These two RSC contract models are comparatively studied. It is found that order quantity and total system profit are larger in cooperative game than in non- cooperative game.
