Ambulance redeployment is the practice of repositioning ambulance fleets in real time in an attempt to reduce response times to future calls. When redeployment decisions are based on real-time information on the status and location of ambulances, the process is called system-status management. An important performance measure is the long-run fraction of calls with response times over some time ...

In this paper, we present a simple implementation of an ambulance robot controller. The responsibility of the ambulance in the system is to transport dead robots from their current location to a nearby charging station. This helps in solving the problem of having dead robots in the environment resulting in a more robust and autonomous system. Results from a simulated MedBot controller indicate ...

We describe an ambulance location optimization model that minimizes the number of ambulances needed to provide a specified service level. The model measures service level as the fraction of calls reached within a given time standard and considers response time to be composed of a random delay (prior to travel to the scene) plus a random travel time. In addition to modeling the uncertainty in th...

Emergency medical services (EMS) generally deal with two real-time decisions: ambulance dispatching and relocation. Dispatching consists in selecting which ambulance to send to an emergency call, while relocation consists in determining how to modify the location of available ambulances throughout the day in response to changes in the state of the system. Although they have been mostly consider...

This paper studies the issue of uncertainty in the ambulance location problem to cover the maximum number of demand points in a city. The work is based on the double standard model (DSM), a popular coverage model where two radii are considered to cover a percentage of the demand points twice. Uncertainty is introduced in the expected travel time between an ambulance and a demand point, before c...

In this paper, we present solution procedures to tackle an ambulance location problem in Austria. We consider the problem as a doublecoverage ambulance location problem, and for specifying it in formal terms, we use an extension of a model developed by Gendreau, Laporte and Semet [11] by introducing a limit on the number of inhabitants served per ambulance. To solve the problem, we reimplemente...

OBJECTIVES Injury related to violent acts is a problem in every society. Although some authors have examined the geography of violent crime, few have focused on the spatio-temporal patterns of violent injury and none have used an ambulance dataset to explore the spatial characteristics of injury. The purpose of this study was to describe the combined spatial and temporal characteristics of viol...

Bystander cardiopulmonary resuscitation (CPR) improves out-of-hospital cardiac arrest (OHCA) survival. In settings with prolonged ambulance response times, skilled bystanders may be even more crucial. In 2010, American Heart Association (AHA) and European Resuscitation Council (ERC) introduced compression-only CPR as an alternative to conventional bystander CPR under some circumstances. The pur...
