摘要：Although there exist numerous literatures on facility layout in manufacturing systems, studies on department layout in hospitals are relatively scarce. In this paper, we proposed a MOEA/D based approach for a hospital department layout problem, where three objectives are simultaneously optimized, namely patient flow cost, the closeness of departments and rearrangement cost. A constraint handling technology is introduced to deal with infeasible solutions. Experiments show that the proposed approach is able to get satisfactory Pareto solutions with lower patients' flow cost and the closeness compared to the original layout, and that the optimized layouts decrease the patients' move time, thereby improving quality of service.
