Hospital Location Selection with Utility Range Based Interactive Group Decision Method

摘要

Selecting a location for a potential hospital often decides the success or the failure of such a facility. It is thus important to assess the locationsfrom multiple dimensions before selecting the site. This paper focuses on the multi factor evaluation of hospital sites using Utility RangeBased Interactive Group Decision Method. The process of site selection is inherently complicated. A careless site imposes exorbitant costs oncity budget and damages the environment inevitably. Nowadays, multi-attributes decision making approaches are suggested to use to improveprecision of decision making and reduce surplus side effects. Utility range based interactive group decision method is proposed for solvingthis complex problem and selection of the location which has the highest utility. Main theme underlying the method is every group memberwants to compare their partial utility information with other group members. This procedure reflects the incomplete information as linear rangebecause it can count easily from partial utility information. Range type makes the incomplete information effective and efficient to demonstratethe group members. In addition to this, range type utility information makes easy to compare every group members’ utility information withgroup’s information and collecting the each group member’s utility information within group’s utility information. To obtain group utility,preference aggregation method is used. Interactive procedure helps to make consensus of the group. Utility information calculated by usingoptimism coefficient which is determined by the group. A numerical example for hospital location selection is given to illustrate the proposedmethod finally.
