Research on Supply Chain Distribution Network of Bi-Level Programming Model based on Two-way Approximation Genetic Algorithm

This study introduces the opportunity cost of distribution network. The centralized and distributed supply chain distribution network of bi-level programming model were constructed by defining the distribution centers face different stock losses, which include one manufacturer, more distribution centers and multiple retailers. Combined with the traditional genetic algorithm, this study designed approximation algorithm in order to optimize and solve the model, and verify the effectiveness of the model and algorithm through an example
