Nowadays in all countries, public resources of health care may be inadequate to meet health care demands. Hence, the policy makers and providers of health care should provide citizens with most effective methods when available resources are limited. During the past decades, a large number of research efforts in the issue of health care and its applicable mathematical models have been considered...
متن کاملAdvanced OR and AI Methods in Transportation A MULTIPERIOD EXPECTED COVERING LOCATION MODEL FOR DYNAMIC REDEPLOYMENT OF AMBULANCES
Emergency response administrators often face the difficult task of locating a limited number of ambulances in a manner that will yield the best service to a constituent population. In this study we try to determine the minimum number of ambulances that meet or exceed a predetermined coverage requirement for dynamic redeployment of ambulances in response to fluctuating demands throughout the wee...
متن کاملA multiperiod set covering location model for dynamic redeployment of ambulances
Emergency medical service (EMS) providers continually seek ways to improve system performance particularly the response time to incidents. The demand for ambulances fluctuate throughout the week, depending on the day of week, and even the time of day, therefore EMS operators can improve system performance by dynamic relocation/redeployment of ambulances in response to fluctuating demand patters...
متن کاملAn Efficient Simulation-Based Approach to Ambulance Fleet Allocation and Dynamic Redeployment
We present an efficient approach to ambulance fleet allocation and dynamic redeployment, where the goal is to position an entire fleet of ambulances to base locations to maximize the service level (or utility) of the Emergency Medical Services (EMS) system. We take a simulation-based approach, where the utility of an allocation is measured by directly simulating emergency requests. In both the ...
متن کاملAn Efficient Heuristic for Real-Time Ambulance Redeployment
We address the problem of dynamic ambulance repositioning, in which the goal is to minimize the expected fraction of late arrivals. The decisions on how to redeploy the vehicles have to be made in real time, and may take into account the status of all other vehicles and accidents. This is generally considered a difficult problem, especially in urban areas, and exact solution methods quickly bec...
