The problem of finding a Master Surgical Schedule (MSS) consists of scheduling different specialties to the operating rooms of a hospital clinic. To produce a proper MSS, each specialty must be assigned to some operating rooms. The number of assignments is different for each specialty and can vary during the considered planning horizon. Realizing a satisfying schedule is of upmost importance for a hospital clinic. Recently, a compact solution based on Answer Set Programming (ASP) to the MSS problem has been introduced and tested with satisfying results, but only on synthetic data. In this paper, we also adapt the encoding and test our overall solution on real data from ASL1 Liguria in Italy. The experiments show that our ASP solution provides satisfying results also when tested on real data.
