Evaluating dynamic dispatch strategies for emergency medical services: TIFAR simulation tool

Abstract: In life-threatening emergency situations, the ability of emergency medical service (EMS) providers to arrive at the emergency scene within a few minutes may make the difference between survival or death. To realize such extremely short response times at affordable cost, efficient planning of EMS systems is crucial. In this article we will discuss the Testing Interface For Ambulance Research (TIFAR) simulation tool that can be used by EMS managers and researchers to evaluate the effectiveness of different dispa… Show more

“…To remain safe, there is a need to monitor and assess the performance of EMS continually [16]. The performance indicators include time/distance indexes such as expected coverage level [17], response time [18], round trip time [19], service time [20] and dispatching time [21], ratio indexes such as loss ratio [22], survival rate [23], and financial index such as capital and operating cost [24]. Many of these indicators reflect the intention of emergency demand or the interest of EMS management [25].…”

“…Los problemas de relocalización dinámica tienen como principal característica que solo consideran la aplicación de políticas de relocalización de las ambulancias cuando hay una disminución en la flota porque se envía uno o varios vehículos a dar respuesta a un evento y/o cuando uno o varios vehículos que se encontraban como no disponibles recuperan su estatus de disponibilidad porque terminaron la prestación del servicio [4], [5], [8], [13], [16], [17], [19], [14], [18], [20], [21], [22], [23], [24], [25], [26], [27], [28]. Por otro lado, en los problemas de relocalización multi-periodo además de aplicar políticas de relocalización cuando hay una variación en el tamaño de la flota, también se aplican políticas de relocalización teniendo en cuenta factores externos al SEM, como son: las variaciones de la velocidad en el trascurso del día, las actividades que se realizan durante el día (horario laboral vs horario de descanso), la semana (días de semana vs fines de semana), el año (días laborales vs días festivos) y el comportamiento del tráfico durante horas pico y no pico [1], [29], [30], [31], [20], [15].…”
