A Maximal Covering Model for Helicopter Emergency Medical Systems
نویسندگان
چکیده
We propose a maximal covering location problem for helicopter emergency medical service system. In the system, the transportation time of each patient to a hospital depends on both locations of helipads for helicopters to land and take off and hospitals for deploying helicopters. The aim of this paper is to provide an optimal location strategy of both the helipads and the hospitals so as to maximize the number of covered demand which can be transported to a hospital within a preset time. The problem can be formulated as an integer linear program. We present numerical examples using an idealized city model and examine optimal solutions obtained.

Covering models have found many applications in a wide variety of real-world problems; nevertheless, some assumptions of covering models are not realistic enough. Accordingly, a general approach would not be able to answer the needs of encountering varied aspects of real-world considerations. Assumptions like the unavailability of servers, uncertainty, and evaluating more factors at the same ti...

The problem of maximal hub covering as a challenging problem in operation research. Transportation programming seeks to find an optimal location of a set of hubs to reach maximum flow in a network. Since the main structure's parameters of the problem such as origin-destination flows, costs and travel time, change periodically in the real world applications, new issues arise in handling it. In t...

Introduction: The main task of the emergency medical system is to provide primary care and transfer the injured to a medical center. Studies have been conducted to investigate the outcome of helicopter and ground ambulance casualties, but they show different results. These different results may be due to the type of study, statistical methods, differences in pre-hospital emergency systems, an...
متن کاملGeneral form of a cooperative gradual maximal covering location problem
Cooperative and gradual covering are two new methods for developing covering location models. In this paper, a cooperative maximal covering location–allocation model is developed (CMCLAP). In addition, both cooperative and gradual covering concepts are applied to the maximal covering location simultaneously (CGMCLP). Then, we develop an integrated form of a cooperative gradual maximal covering ...
