İzmir'de bir hastanenin acil servis departmanı için bir simülasyon optimizasyonu çalışması

The long waiting times of patients and congestion are the most important problems of emergency departments (EDs) in the hospitals. In this thesis, for an ED of a hospital in İzmir, the aim is to find the optimal allocation of resources while minimizing the average overall flow time of patients (length of stay) and keeping the utilization ratios of doctors and nurses at the target levels. First of all, the simulation model of the ED is developed to evaluate the current system performance. Secondly, the data obtained from the simulation model is used in Nested Box-Behnken Design for building metamodels. Lastly, Derringer-Suich multi response optimization procedure is applied to minimize average overall flow time of patients and to keep utilization ratios of doctors and nurses at target levels. This study will provide help for healthcare decision makers to find the optimal configuration of resources in ED while considering to satisfy multi objectives simultaneously.
