本文提出了新的急救医疗服务站选址模式。这些模型是通过在现有的覆盖模型中加入生存函数来生成的。生存函数是返回患者生存概率的紧急医疗服务(EMS)车辆对患者的响应时间的单调递减函数。生存函数允许计算有形的结果衡量标准--心脏骤停情况下的预期存活人数。生存最大化选址模型比覆盖模型更适合于EMS选址，后者不能充分区分不同响应时间的结果。我们使用埃德蒙顿EMS系统的数据，实证地证明了生存最大化模型的优越性。(C)2007年威利期刊公司。
This article proposes new location models for emergency medical service stations. The models are generated by incorporating a survival function into existing covering models. A survival function is a monotonically decreasing function of the response time of an emergency medical service (EMS) vehicle to a patient that returns the probability of survival for the patient. The survival function allows for the calculation of tangible outcome measures-the expected number of survivors in case of cardiac arrests. The survival-maximizing location models are better suited for EMS location than the covering models which do not adequately differentiate between consequences of different response times. We demonstrate empirically the superiority of the survival-maximizing models using data from the Edmonton EMS system. (C) 2007 Wiley Periodicals, Inc.
