Resumen de Nonlinear Differential Equations in Cross-border E-commerce ControllingReturn Rate

Yun Zhang

• This article constructs a nonlinear differential equation model that incorporates non-defective return factors andminimizes the expected cost of the inventory control problem under the cross-border e-commerce overseas warehouse model. Under the dynamic background, the problem of pricing and shop assistant decision-making inthe supply chain is studied, and the differential game model is constructed. We use differential game theory togive pricing and store assistance strategies under decentralized and centralized decision-making. At the same time, we designed a contract to achieve supply chain coordination in this context. Numerical examples calculate the optimal return price and optimal order quantity under supply chain coordination
