  1. Accurate estimation of expected coverage : a comparative study.

    Article - En anglais

    The accurate estimation of « expected coverage » is an important issue in the application of set covering approaches to emergency medical service (EMS) location problems.

    The first article to define and utilize expected coverage was published by Daskin in 1992.

    Batta et al. recognizes the inaccuracy of solutions obtained via Daskin's model and proposed an adjustment to improve the expected coverage predicted by it.

    Recently, Bernardo and Repede presented a modified model that reportedly estimates expected coverage more accurately relative to the previous models.

    In this study, each of these models was applied to a wide range of simulated EMS system scenarios.

    Our findings suggest that none of the expected covering models is consistently more accurate than the others.

    Additionally, our results support Batta et al.'s recommendation that a hypercube-bases model should be used for post-optimality analysis.
