In addition, it is important to develop an efficient treatment room schedule.

  This treatment room schedule is intended for a variety of patients whose irradiation time (treatment room occupation time) varies depending on treatment contents. For example, patients who use the first treatment room on a certain day are patients A and B. , And patient C, and the order of irradiation is patient B → patient A → patient C. The patients who use the second treatment room on that day are patient D, patient E, and patient F, and the irradiation order is created as a treatment room use plan such as patient F → patient E → patient D. .
