摘　　要：考虑市场的随机需求,研究从制造商到最终客户的多层供应链与供应链的竞争问题,根据给定的假设条件和存在的问题进行分析,选取供应链网络的利润最大化为择优标准,利用变分不等式理论构建了具有随机需求的多供应链竞争网络模型,刻画了多供应链之间的竞争行为。通过用修正投影算法求解文中算例,对算例计算结果进行了分析,分析结果验证了模型的合理性,为以后分析供应链形成过程奠定一定的理论基础。Considering the stochastic consumer demand,we study a multi-tier supply chain versus supply chain competition problem from manufacturers to end consumers. We choose profit-maximization to analyze the multi-supply chains,and based on the variational inequality theory,we developa multi-supply chain competition model with stochastic demands according to the assumptions and analysis of the problem. The model can be used to describe the competition behavior among multi-supply chain. In addition, we construct a numerical example,and compute the example by modified projected algorithm, which can prove the rationality of the model and lay a theoretical foundation for a future research on the supply chain.
