当紧急医疗服务(EMS)调度中心获得实时交通和出行时间数据时，可以使用实时而灵活的调度策略来节省EMS关键的响应时间。这项研究致力于开发一个优化模型，以开发灵活的调度策略，利用可用的实时出行时间信息。该问题被描述为一个整数规划模型，其中使用了一种动态最短路径算法。应急车辆和事故被分成不同的类别，以便纳入不同的约束条件。仿真实验演示了该公式在实时交通条件下的工作原理。该仿真模型的主要模块包括行程时间预测、动态最短路径事件/车辆跟踪和调度优化。该仿真模型是一个实时EMS系统的概念设计
When real-time traffic and travel time data are available to Emergency medical services (EMS) dispatch centers, a realtime and flexible dispatching strategy could be used to save crucial response time for EMS. This research concentrates on developing an optimization model for developing flexible dispatching strategies that take advantage of available real-time travel time information. The problem is formulated as an integer programming model in which a dynamic shortest path algorithm is used. Emergency vehicles and incidents are divided into categories so that different constraints could be incorporated. A simulation experiment demonstrates how this formulation works under real-time traffic conditions. The major modules of this simulation model include travel time prediction, dynamic shortest path incident/vehicles tracking, and dispatch optimization. This simulation model is a conceptual design of a real-time EMS system
