A Multi-attribute Decision Making Approach for Trauma Center Site Selection

To make sophisticated decisions considering multiple conflicting criteria, such as choosing the location of a new facility is common for environmental managers. The environment and health of city inhabitants are greatly damaged if the selection of a site is wrong. In a metropolitan city, site selection for a trauma center is a quite tough decision taken by policymakers. Considering the minimal time, pollution and cost, this paper aims to overcome the challenges of selecting a site for a trauma center. A Multi-Criteria Decision Analysis process is developed which combines Analytic Hierarchy Process (AHP) with a utility-based method generic feature extraction approach (GFEA) to determine the optimum site for a new trauma center. In this study, 10 attributes among 5 different locations of Metropolitan city are considered as alternatives. AHP generates relative importance of the alternatives. The utility score is proposed using the GFEA method and the arithmetic points drawn by the alternatives make the final decision. Finally, a numerical study is presented to validate the possible alternative of the proposed methodology.
