Modélisation, analyse et pilotage de flux en milieu hospitalier à l'aide d'UML et des réseaux de Petri

Abstract : Traditional business process modelling approaches and operational research methods have been used to model and understand complex health care systems. However, special features of these systems cannot be captured by traditional modelling tools. Our goal is to develop a methodology which is able to capture particularities of health care system. We introduce the medPRO (medical Process-Resource-Organisation) modelling and simulation framework in this thesis, designed for analysis and simulation of health care systems. This framework consists of a list of generic resources and activities description, and a handbook describing the base system. UML (Unified Modelling Language) has been chosen to model these systems. Several points of view have been selected : Process (patient centred view), Resource (behaviour of human and material resources) and Organisation (relation between actors). Dynamic behaviour of the model is specified using a special class of Petri nets, called Health Care nets: a discrete-event simulation algorithm has also been developped for Petri nets. A large part of this work is dedicated to the decision system, which is used (i) to apply planning and scheduling methods from industrial engineering to health care systems, and (ii) to control the simulation process in real-time using a hierarchical/heterarchical hybrid approach. Three case studies are also presented to show the efficiency of the medPRO framework: we investigated the neuro-vascular unit, the pharmacy unit and the operating theatre of the universitary teaching hospital of Saint-´ Etienne (France). Special optimization tools were developped and included in the framework.
