摘要
针对供应链网络结构,从系统论的角度应用信息熵概念,定义了供应链的聚合度,建立了供应链系统稳定性的数学模型,通过聚合度、冗余度指标揭示了供应链的抗干扰能力和稳定性.分析了一个供应链的稳定性,得出聚合度、冗余度等指标可以反映供应链的稳定性.
A measurement model about stability of a supply chain network is presented, which is based on information entropy and from system point of view, First, a definition on ascendancy of a system is given. Then, a model with redundancy and redundancy as indicators of anti-jamming ability and stability of a supply chain is developed. Finally, a case is provided to validate the method. It is shown that ascendancy and redundancy can serve as indexes of stability of a supply chain network.
