Abstract: One of the problems faced in the process of operating room scheduling is the uncertainty in the surgical duration. Surgical duration uncertainty often causes the hospital to change the initial operating room schedule, even the schedule can not be started earlier. This system leads to prolonged patient waiting time and staff overtime. This study develops a mathematical model for operating room scheduling which aims at minimizing patient waiting time and staff overtime. Clustering analysis is used to determine the priority in scheduling patients while hill climbing is developed to solve the model to find out daily operating room schedule. Computational experiment was performed based on real surgery data of elective patients to examine performance quality of this proposed model. The results indicate that waiting time and overtime experience a decrease of 40.04 and 29.54%, respectively compared to real conditions.
