Abstract: Recent decades have witnessed on the one hand a much greater and tighter integration of goods or services supply systems and growing interconnectedness as well as changing organizational and operational factors, and on the other hand an increased social vulnerability in the face of accidental or intentional disruption. The work of the International Risk Governance Council (IRGC) in the field of critical infrastructures has focused on both the risks associated with five individual infrastructures and the issues associated with the increasing interdependence between them. This paper presents a selection of system weaknesses and a number of policy options that have been identified and highlights issues for further investigation and dialogue with stakeholders. Furthermore, the need to extend current modeling and simulation techniques in order to cope with the increasing system complexity is elaborated. An object-oriented, hybrid modeling approach promising to overcome some of the shortcomings of traditional methods is presented.
