An integrated method to solve the healthcare facility layout problem under area constraints

In this paper, the healthcare facility layout problem with area constraints is considered, a proper departments arrangement is selected such that the operating cost and system efficiency are guaranteed. We propose an integrated method to consider both quantitative and qualitative criteria to get a synthesize rank of the feasible alternatives. On quantitative aspects, several feasible layout solutions are generated with the ranking of operation cost; On qualitative aspects, the layout alternatives are evaluated by experts on their multiple attributes, the evaluation scores given by experts are in the form of intuitionistic fuzzy sets. We assume that the weights of attributes and experts are partially known or unknown in advance, and the weights of each expert on different attributes are different. An illustrative example is shown to demonstrate the application of the proposed methodology.
