Daily Operating Room Schedule Taking into Account the Preferences of Hospital Physicians (Case Study of Imam Khomeini Hospital)

The issue of allocating the capacity of operating rooms to different departments of surgery is done by observing the decisions made at the strategic level of hospital decisions. Therefore, operating room scheduling plays an important role in increasing their productivity and reducing hospital costs. On the other hand, due to various uncertainties in operating room activities, this issue can be very challenging. In this case, according to the defined objective function and also the existing limitations, the capacity of operating rooms is allocated to different surgical groups. Therefore, in this model, the daily schedule of surgeries in two stages of surgery and recovery and considering all the real limitations in hospitals has been investigated. This issue determines the sequence, start time of each surgery and allocation of resources required in each stage with the aim of minimizing the total cost of employing surgeons according to the differences in their skills, performance and preferences.
