碩士 === 長庚大學 === 資訊管理學系 === 99 === To provide a comprehensive service, emergency room is a unique medical unit that requires a schedule of shift within which enough doctors shall be assigned properly to each time slot on the table. What is the proper scheduling depends on its fitness of regulations, on whether it satisfies individual doctor’s preference or not, and on its fairness. Since the rotation of the emergency room schedule takes a rather special form due to the fact that the working time of emergency room doctors is different from that of normal clinic doctors, the key of such a scheduling issue can be on how to balance the physical and mental faces of a doctor within a usual day-night shifts. In order to solve this problem, we propose a goal programming model considering doctors’ preferences by objective weighting, and hope that the model can leverage related concerns pertaining to emergency room scheduling and can make this problem mathematically manageable. By the way, this study proposes actually two models by using two types of objective functions: one takes Mean Absolute Deviation (MAD) while the other takes MINMAX. We not only compared the schedules solved against that original one which was arranged by human heuristic, but also compared the two obtained schedules to, to understand which model is better for solving the encountered problem. As the result, we have revealed that the model taking MINMAX in its objective function attains a better solution for fairness than that taking MAD. Moreover, in compare with the original version of schedule, the output schedules by taking both models not merely can satisfy all the criteria and constraints, but also can lower the duty of each doctor. This make the proper scheduling under limited human resource possible, and will offer sufficient rest time to emergency room doctors.
