Configurable Domain Objects for Resource Modelling in Treatment Scheduling

Abstract

This paper presents the concept and realization of configurable resource models as extension of a treatment scheduling system for users in the medical sector. Our approach aims to ease the handling of automated treatment scheduling by domain experts without the immediate assistance of IT-experts. Configurable resource models were integrated into our automated treatment planning system for medical facilities and support a user-friendly configuration of resources such as specialized treatment rooms, medical devices, or medical staff. In our approach, treatment process models are defined in the BPMN workflow-language by the domain experts. The new concept of configurable resource models allows the end-user to interactively describe the available resources in their environment. These descriptions (i.e. configurable resource objects or CDOs) can then be linked to activities specified in the treatment models. Together, CDOs and the BPMN treatment models are automatically transformed into CSPs, i.e. mathematical descriptions which can be solved by constraint solvers, thus yielding optimal treatment plans.
