We introduce an estimation method for calculating operation durations using regression analysis and a mixed-integer programming model for the operating room (OR) scheduling problem. We develop an OR scheduling system and apply it to OR scheduling at Aichi Medical University Hospital. The goals of scheduling are to reduce staff overtime, schedule changes, and OR reassignment. We attain this by scheduling according to predicted operation durations. The resulting schedule makes highly efficient utilization of the OR. We confirm the efficiency of the schedules obtained by comparing them to schedules created manually.
