Decision making of product quality and carbon emission reduction in footwear supply chain under production capacity constraint

For the supply chain composed of raw material suppliers and footwear manufacturers, considering the limitation of supplier production capacity, this study was based on the balance of raw material production quantity and quality. In this paper, the game theory was used to establish one centralized decision-making model and one decentralized decision-making model. Then, under these two decision-making models, the optimal decision-making problems such as raw material quality and manufacturer carbon emission reduction were studied, and sensitivity analysis was also made through simulation. The research results show that when the quality of the supplied raw materials under these two models is the same, the demand for the products is also the same, and the total profit is relatively larger in decentralized decision-making; when the carbon emission reduction degree of the two decision-making models is the same, the quality requirements for raw materials are higher in the centralized decision-making, but their demand and total profit are relatively low.
