Research on Robust Financing Strategy of Uncertain Supply Chain System Based on Working Capital

In the supply chain system, the working capital is the core factor of normal operation for each node enterprise, but the internal and external uncertainties seriously affect the stability of working capital. Therefore, how to effectively manage the dynamic working capital in the uncertain supply chain system is a challenge. This article aims to investigate a robust financing strategy of the uncertain supply chain system by introducing the fuzzy control theory. First, a basic dynamic working capital operation model of the supply chain system with the internal and external uncertainties is constructed. Then, in terms of the corresponding financing strategies for the different idle working capital levels, a multimodel supply chain system is designed based on the basic model. Second, the Takagi-Sugeno fuzzy system is used to transform the multimodel system into a fuzzy switching model. Third, a robust financing strategy is proposed to suppress the impact of uncertainties on the supply chain system. This robust financing strategy can not only guarantee the stability of the uncertain supply chain system, but also reduce the financing cost. Finally, the effectiveness of the proposed robust financing strategy is verified by the results of simulation experiments.
