A System Modeling and Analysis Framework for Risk Analysis in Socio-technical Systems
Résumé
A complex system, which integrates multiple technologies into a socio-technical system, is composed of heterogeneous and interacting sub-systems, components, or human actors evolving in a moving environment. For this reason a complex system will have to face unpredictable and unforeseen events throughout its lifecycle, which can induce unexpected behaviors and risky situations. These behaviors and situations can result in undesirable outcomes regarding the system's performance (in terms of delay, cost, and quality of service, for example), its stability and its integrity. So, how is it possible to design a more robust system that copes with risks? In industry, risk management approaches have been successfully developed in parallel with systems engineering approaches (CAS Enterprise Risk Management Committee 2003). But they generally remain separated from each other or adapted to the study of given phenomena in some domain (such as a nuclear plant, a manufacturing plant, or the food industry). Our goal is to integrate different concepts and tools—from system theory, system engineering practices, and theoretical principles of risk management—into a framework for modeling and analyzing complex systems.
