Research on supply chain finance decision-making for spare parts of auto manufacturers

Supply chain finance aims to alleviate supply chain financial problems by planning, guiding and controlling the flow of funds in the supply chain, promoting the sharing of relationship resources, capabilities, information and risks among related enterprises, and ultimately realizing win-win benefits for all parties. The theory of supply chain finance is introduced into the supply of spare parts in automobile manufacturers. And in order to analyse its mechanism and operating characteristics, the Bass diffusion model is adopted to analyse the diffusion mode of supply chain finance among suppliers, the extra profit model of automobile manufacturing enterprises is established based on the IFR (Incremental Failure Rate) distribution, and the algorithm for solving the decision-making parameter is designed. The results show that the model can provide decision support for automobile manufacturers on taking supply chain financial measures through the optimization calculation of key decision parameters, so as to guarantee the high reliability and low risk of the suppliers when maximizing the benefits of stakeholders involved in the supply chain.
