Building evolution model of supply chain networks could be helpful to understand its development law. However, specific characteristics and attributes of real supply chains are often neglected in existing evolution models. This work proposes a new evolution model of supply chain with manufactures as the core, based on external market demand and internal competition-cooperation. The evolution model assumes the external market environment is relatively stable, considers several factors, including specific topology of supply chain, external market demand, ecological growth and flow conservation. The simulation results suggest that the networks evolved by our model have similar structures as real supply chains. Meanwhile, the influences of external market demand and internal competition-cooperation to network evolution are analyzed. Additionally, 38 benchmark data sets are applied to validate the rationality of our evolution model, in which, nine manufacturing supply chains match the features of the networks constructed by our model.
构建供应链网络演化模型有助于理解其发展规律。然而,现有演化模型往往忽视了真实供应链的具体特征和属性。这项工作基于外部市场需求和内部竞争合作,提出了一种以制造商为核心的新型供应链演化模型。该演化模型假设外部市场环境相对稳定,考虑了包括供应链特定拓扑结构、外部市场需求、生态增长和流量守恒等多个因素。仿真结果表明,我们模型演化出的网络具有与真实供应链相似的结构。同时,分析了外部市场需求和内部竞争合作对网络演化的影响。此外,应用38个基准数据集来验证我们演化模型的合理性,其中九个制造业供应链符合我们模型构建的网络特征。
