| Abstract: | This study develops a multi-stage stochastic model that describes the complete scheduling framework of a radiology department. The framework is adapted to allow for up to 60% of the session schedule, the patient capacity per imaging modality, to be determined one month in advance, enhancing scheduling flexibility based on patient demand and employee availability while considering fairness of the schedule. The results of a test case showed that a fixed myopic model outperforms the flexible models unless the demand deviates from the mean for prolonged periods. The flexible introduced more fluctuations in the work backlog. Moreover, a case study regarding VieCuri Medical Centre similarly showed that a myopic method performs comparably to the two-stage stochastic method using 50 scenarios. The heuristic using a regular mixed integer linear program and the flexible scheduling framework showed similar performance to the stochastic two-stage method. Furthermore, VMC’s current management maintains a more stable work backlog for most modalities than the proposed flexible model. However, our results show a proof of concept for a flexible method that can make operational adjustments earlier and offers the opportunity to adjust the session schedule while maintaining a decent work backlog and an equally or more stable RT schedule. |
