战略定位和分配应急响应和/或资源，以潜在的紧急事件是非常重要的决策，灾害管理计划。本文提出了一种可靠的多类型联合服务设施选址模型，该模型考虑了多种类型的响应站的合作服务的需要，以及站中断的概率风险。该问题被配制成一个混合整数非线性规划，并通过一组定制的线性规划和拉格朗日松弛算法来解决。数值实验的假设和全尺寸的情况下进行，以证明该模型的适用性，并得出管理见解。
Strategic positioning and allocation of emergency responders and/or resources to potential emergency incidents are very important decisions for disaster management programs. In this paper, a reliable multi-type joint-service facility location model is proposed, which takes into consideration the need for cooperative service from multiple types of responder stations, as well as the probabilistic risk of station disruptions. The problem is formulated as a mixed-integer non-linear program and solved via a set of customized linear program and Lagrangian relaxation based algorithms. Numerical experiments on hypothetical and full-scale cases are conducted to demonstrate the applicability of the model and to draw managerial insights.
