Nuclear Medicine Scheduling via Answer Set Programming

The Nuclear Medicine Scheduling (NMS) problem consists of assigning patients to a day, in which the patient will undergo the medical check, the preparation, and the actual image detection process. The schedule of the patients should consider the different requirements of the patients and the available resources, e.g., varying time required for different diseases and radiopharmaceuticals used, number of injection chairs, and tomographs available. In this paper we present a solution where modeling and solving are done via Answer Set Programming. Experiments employing real data show that the solution provides satisfying results in a short time.
