A review on coverage models applied to emergency location

The management of hospital logistics emergency was addressed by several researchers around the world. Improving the efficiency of emergency activities is among the priority fields of the health strategy. In order to achieve this goal, the management and the modelling of the ambulance fleet are the main approaches exploited by researchers to ensure an optimal coverage of a territory. This paper gives a critical overview of coverage models existing in literature. It analyses these models classified under three classes. The static class focuses on the earlier models about emergency location coverage. The probabilistic class defines the ambulance unavailability ratio. The dynamic class describes how to reassign dynamically the vehicles. Next, the paper sheds new light on several parameters used during simulation of coverage models. Such a paper that combines the classification of existing models, the mathematical programming methods and the simulation parameters, extends the researches of emergency management system.
