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.

应急响应者和/或资源对潜在紧急事件的战略定位和分配对于灾难管理计划而言是非常重要的决定。在本文中，提出了一种可靠的多类型联合服务设施选址模型，该模型考虑了来自多种类型的响应站的协作服务的需求以及站中断的概率风险。该问题被公式化为混合整数非线性程序，并通过一组定制的线性程序和基于拉格朗日松弛的算法来解决。进行了假设和全面案例的数值实验，以证明该模型的适用性并得出管理上的见解。
