Operating room scheduling comprises determining the specific start timings for surgeries and allocating the necessary resources to each scheduled surgery. It takes into account multiple limitations to ensure a comprehensive surgical process, including the availability of resources, specialties, and restrictions. Several surgeons have different specialties, and each has a waiting list of patients whose surgeries must be scheduled on the days the surgeons are in one of the operating rooms. In addressing this matter, two objectives are taken into account: minimizing expenses associated with overtime and unutilized operating rooms, while maximizing the number of days patients wait for surgery. The resolution of this problem involves two approaches: mathematical modeling and optimization through simulation-based methods. The findings indicate that when addressing the operating room scheduling issue, the simulation-based optimization solution matches the quality of the solution provided by the mathematical model for smaller problems and offers a timely and satisfactory solution for larger-scale problems.
