Uml-statechart Modeling Tool for the Vle Simulator: an Application to a Chronic Renal Dialysis Unit

The various reforms of the health care system aim at reducing the corresponding costs. So the hospitals must rationalize their costs while guaranteeing a good quality of service. In order to reach this goal, different scenarios of health care unit management have to be envisaged and carefully evaluated before their implementation on the system. Thus, simulation is used more and more frequently to evaluate the performances related to the reorganization of the health care units. However the elaboration of accurate simulation models is not an easy task. In this paper, we use a modeling tool dedicated to performance evaluation via the VLE (Virtual Laboratory Environment) simulator in the case of a chronic renal dialysis unit reorganization. The modeling part is based on the UML statecharts (Unified Modeling Language) which are used to generate VLE simulation model and XML file for the parameterization
