Abstract

Supply chain (SC) has been increasingly challenged by disruption events (DEs), where super DEs (SDEs) comprising a sequence of DEs, e.g., COVID-19, pose significant threats with long-term impacts. To hedge against SDEs, SC viability has been introduced, whose distinctive feature is the ability to adapt the SC structure. Building SC viability via dynamic SC structural adaptation under SDEs, however, has not been quantitatively addressed in the literature. This study investigates a novel viable SC building problem under SDEs. It consists of timely assessing the disruption risk and dynamically adapting the SC structure, to satisfy uncertain demands. The aim is to find the best balance between the disruption risk and the SC operational cost. To portray the structural and temporal risk propagations along the dynamic SC structure, a new structure-variable dynamic Bayesian network (SVDBN) is proposed. Then, a bi-objective mixed-integer non-linear programming (MI-NLP) model is established. Based on analyses of problem features, a decomposition-and-clustering (DC) heuristic algorithm is designed to solve the problem. Numerical experiments are conducted to evaluate the performance of the approach, and managerial insights are provided as well.

在超级中断事件下构建可行供应链的动态结构适应

供应链（SC）日益受到中断事件（DEs）的挑战，其中由一系列中断事件（例如COVID-19）组成的超级中断事件（SDEs）构成具有长期影响的重大威胁。为了对冲SDEs，引入了SC生存能力，其显著特征是适应SC结构的能力。然而，在SDEs下，通过动态SC结构适应来建立SC生存能力，在文献中尚未得到定量解决。本研究探讨了一种新的在SDEs下可行的SC建造问题。它包括及时评估中断风险和动态调整供应链结构，以满足不确定的需求。其目的是在中断风险和供应链运营成本之间找到最佳平衡。为了描述动态SC结构的结构和时间风险传播，提出了一种新的结构变动态贝叶斯网络（SVDBN）。然后，建立了双目标混合整数非线性规划（MI-NLP）模型。在分析问题特征的基础上，设计了一种分解聚类（DC）启发式算法来解决问题。数值实验进行了评估该方法的性能，并提供了管理的见解。
