Abstract : Sterilization services are vulnerable to risks, due to the contagious nature of their environment and to the degradation that risks can cause to their performances and to the safety of patients and staff. The risks in these facilities can range from equipment failure to the transmission of nosocomial infections and diseases. In this kind of high risk environment, these services are also required to maintain an adequate level of performance to ensure continuity of care in operating theaters.We focus in this research on the development of an integrated approach for risk analysis and performance assessment. This work is part of a collaborative work between the G-SCOP laboratory and the sterilization service of the University Hospital of Grenoble, which was the case study chosen to implement the proposed approach.The approach we propose is conducted in several steps: first, following a comparison of the risk analysis methods, we have chosen a model driven approach called FIS (Function Interaction Structure). Based on FIS, we have developed a risk model of Grenoble University Hospital sterilization service. This model describes the functions, the resources to achieve these functions as well as the various risks that may be encountered. Secondly, we introduced a new view to the FIS model dedicated to describe the dynamic behaviour of the resulting risk model.This dynamic model can simulate the behaviour of the sterilization service in normal situations of operations and risk situations.To do this, we have introduced a new Petri Net class called PTPS (Predicate-Transition, Prioritized, Synchronous) Petri Net to represent and simulate the dynamic behaviour of the FIS model. Subsequently, we automated the switching between the risk model and the dynamic model. This automation is performed by a set of translation algorithms capable of automatically converting the FIS model to a PTPS Petri Net simulation model .This approach resulted in a modelling and simulation tool in degraded mode called SIM-RISK. We also showed the usefulness of this tool by some examples based on different risks encountered in the sterilization service.
