研究了一个两级供应链的设计问题，其中一组供应商为一组接收不确定客户需求的终端提供服务。特别是，我们考虑了可能导致某些供应商的产品供应中断的概率运输中断。我们将这一问题表示为一个整数非线性规划，以确定使期望总成本最小的最优系统设计。提出了一种基于拉格朗日松弛的定制求解算法，有效地求解了该模型。通过几个数值实例对所提出的模型进行了检验，并对关键参数如何影响最优系统设计提供了管理方面的见解。(C)2016爱思唯尔有限公司。保留所有权利。
This paper studied the design of a two-echelon supply chain where a set of suppliers serve a set of terminals that receive uncertain customer demands. In particular, we considered probabilistic transportation disruptions that may halt product supply from certain suppliers. We formulated this problem into an integer nonlinear program to determine the optimal system design that minimizes the expected total cost. A customized solution algorithm based on Lagrangian relaxation was developed to efficiently solve this model. Several numerical examples were conducted to test the proposed model and draw managerial insights into how the key parameters affect the optimal system design. (C) 2016 Elsevier Ltd.
