Cooperative Incentive Model of Supply Chain Quality Control Based on Cost-sharing Contract

Abstract

In order to motivate suppliers to invest more efforts to improve product quality, a game-theoretic optimization model was used to build a retailer-multi-vendor cooperative quality control incentive model based on cost-sharing contracts, and the effectiveness and rationality of the model are verified by an example. The results show that the quality control cooperation incentive model can improve the coordination effect and share the supplier’s quality control costs through retailers to promote suppliers to invest more quality efforts, increase the profits of retailers and suppliers, and thus achieve the overall profit of the supply chain maximize.
