چکیده
As the main source of income and expenses of hospitals, operating rooms (ORs) are the engines of hospitals' economics and they have a significant impact on public health. Many papers concerned regarding OR planning and scheduling problems, but they have not considerably applied the simulation-based optimization approach to solve the problems. In OR scheduling problems, there are a number of ORs and some surgeons with different specialties and each surgeon has a waiting list of some patients that each surgery should be planned and scheduled on the days when relevant surgeons are available. In this study, we consider two objectives: (1) minimizing the costs of overtime staffing and ORs’ idle time, and (2) minimizing the number of waiting days for patients. The mathematical model of OR scheduling problem is developed and solved by both exact method and simulation-based optimization approach. The comparison of results obtained from exact method and simulation-based optimization approach indicates that the exact method is only able to solve the small-size problems in reasonable time, while simulation-based optimization approach find competitive solutions for both small-size and large-size problems and solve large-size problems in an acceptable time.

چکیده [English]
نقش اتاق‌های عمل در سلامت جامعه و اقتصاد بیمارستان‌ها در سال­های اخیر، توجه بسیاری از پژوهشگران را به مسئلۀ زمان‌بندی اتاق عمل جلب کرده است، اما برای حل این مسئله، از قابلیت‌های روش بهینه‌سازی مبتنی­بر شبیه‌سازی، استفادة چندانی نشده است. تعدادی جراح با تخصص‌های گوناگون و هریک با لیست انتظاری از بیماران وجود دارد که جراحی‌های آن­ها باید در روزهای حضور جراحان در یکی از اتاق‌های عمل زمان‌بندی شود. برای این مسئله، دو هدف کمینه­کردن هزینه‌های اضافه‌کاری و خالی­ماندن اتاق‌های عمل، و کمینه­کردن روزهای انتظار بیماران برای جراحی درنظر گرفته شد. حل این مسئله، به دو روش مدل‌سازی ریاضی و بهینه‌سازی مبتنی­بر شبیه‌سازی صورت گرفت. مطابق نتایج، برای مسئلة زمان‌بندی اتاق عمل، راهکار بهینه‌سازی مبتنی­بر شبیه‌سازی، نه‌تنها در مسائل کوچک، به­لحاظ کیفیت جواب قابل‌رقابت با مدل ریاضی است، بلکه این راهکار قابلیت آن را دارد که در مسائل بزرگ، جوابی مناسب در زمانی معقول پیدا کند.
