碩士 === 長庚大學 === 醫務管理學研究所 === 97 === By using simulation technique, the thesis built a fully constructed operating room model. It allowed managers to follow the different demands and strategies, doing the simulation analysis; besides, adjusting variety variables to choose the fitness plan for the operating room management. In order to display the ability of the model, the research used the data of an operating room in a hospital as an example. It calculated some parameters, such as the average prepared time before conducted the surgeries, the surgical time distribution of each departments, the average arranged time after the surgeries, and the mean time that patients stayed in the recovery room. Then demonstrated the model which was suited the subject, so as to simulate patients’ average waiting time, utilization of operating room, and provider's overtime. The result of the simulation has shown that when increasing patients' arrival rates, the utilization of operating room would be raised. Moreover, it would also heighten patients’ waiting time and provider's overtime. In addition, assumed the quantity of visitor was fixed, the utilization of operating room in plans were almost the same with each other, but it would enhance patients’ waiting time as cutting down the patients’ inter-arrival time, however, provider's overtime could be shorten obviously in most of the departments. In conclusion, according to the result of simulation, the study explored three strategies: First, decreasing patients’ waiting time as a top priority; second, increasing utilization of operating room as a top priority, and third, for the sake of reducing provider's overtime. By discussing the outcomes of different operating scheduling plans, the research presented the process of how to choose the best plan for the managers of the operating room.
