最近的事件突显了规划者在设计供应链网络时需要考虑中断的风险。供应链中断有多种原因，并可能采取多种形式。一旦发生中断，关于供应链基础设施的资源就很少了，因为这些战略决策不能很快改变。因此，在设计供应链网络时考虑到中断是至关重要的，这样即使在中断之后，它们也能很好地运行。事实上，只需对基础设施进行少量额外投资，这些系统往往就能变得更加可靠。规划者在设计有弹性的供应链网络时有一系列的选择，他们选择的方法将取决于可用的财政资源、决策者的风险偏好、正在考虑的网络类型以及其他因素。在本教程中，我们介绍了一系列用于设计对中断具有弹性的供应链的模型。我们首先根据现有网络的状态对这些模型进行分类：可以从头开始设计网络，也可以修改现有网络以防止某些设施中断。接下来，我们根据基础优化模型(设施选址或网络设计)和风险度量(预期成本或最坏情况成本)划分每个类别。
Recent events have highlighted the need for planners to consider the risk of disruptions when designing supply chain networks. Supply chain disruptions have a number of causes and may take a number of forms. Once a disruption occurs, there is very little recourse regarding supply chain infrastructure because these strategic decisions can- not be changed quickly. Therefore, it is critical to account for disruptions during the design of supply chain networks so that they perform well even after a disruption. Indeed, these systems can often be made substantially more reliable with only small additional investments in infrastructure. Planners have a range of options available to them in designing resilient supply chain networks, and their choice of approaches will depend on the financial resources available, the decision maker's risk preference, the type of network under consideration, and other factors. In this tutorial, we present a broad range of models for designing supply chains resilient to disruptions. We first cat- egorize these models by the status of the existing network: A network may be designed from scratch, or an existing network may be modified to prevent disruptions at some facilities. We next divide each category based on the underlying optimization model (facility location or network design) and the risk measure (expected cost or worst-case cost).
