The Operating Room Scheduling (ORS) problem deals with the optimization of daily operating room surgery schedule. It is a challenging problem given it is subject to many constraints, like to determine the start time of different surgeries and allocating the required resources, including the availability of beds in different units. In the last years, Answer Set Programming (ASP) has been successfully employed for addressing and solving the ORS problem. However, due to the inherent difficulty of retrieving real data, all the analysis on ORS encodings have been performed on synthetic data so far. In this paper, instead, we deal with the real case of ASL1 Liguria, and present adaptations of the ASP encodings to include real requirements of such case. Further, we analyze the resulting encodings on these real data. Results on some scenarios show that the ASP solutions produce satisfying results also when tested on real, challenging data.

Abstract
The Operating Room Scheduling (ORS) problem deals with the optimization of daily operating room surgery schedule. It is a challenging problem given it is subject to many constraints, like to determine the start time of different surgeries and allocating the required resources, including the availability of beds in different units. In the last years, Answer Set Programming (ASP) has been successfully employed for addressing and solving the ORS problem. However, due to the inherent difficulty of retrieving real data, all the analysis on ORS encodings have been performed on synthetic data so far. In this paper, instead, we deal with the real case of ASL1 Liguria, and present adaptations of the ASP encodings to include real requirements of such case. Further, we analyze the resulting encodings on these real data. Results on some scenarios show that the ASP solutions produce satisfying results also when tested on real, challenging data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
