Abstract: According to the characteristics of community facilitated O2O, a model of three echelon supply chain is constructed, which consists of the suppliers, the cooperative stores and the community market. The behavior of the decision makers and the optimization conditions are analyzed, and it uses the variational inequality theory to solve the equilibrium state of the whole network. Numerical simulation is conducted to demonstrate the effectiveness of the proposed model, where the impact of the value of relationship and the acceptance degree of network channel on the whole supply chain transaction are discussed. And it provides scientific analysis basis for the stable development of community facilities O2O.

Key words: community facilities Online to offline（O2O）, supply chain, supernetwork, variational inequality

摘要： 针对社区便利O2O自身的特征，构建了由供货商、各合作门店以及小区市场组成的三层供应链超网络模型。分析模型中各决策者的行为以及优化条件，利用变分不等式理论求解整个网络达到均衡状态的条件。设计算例并进行数值仿真，探讨了关系价值重视度以及网络渠道的接受程度对整个供应链均衡决策的影响，验证了模型的有效性，为社区便利O2O供应链的稳定发展提供科学的分析依据。
