Critical Infrastructures and Network Systems:
Statistical Properties and Modelling for Reliability, Risk, Vulnerability and Resilience Analyses
Critical infrastructures are distributed network systems which provide essential services for everyday life, such as water, food, energy, transport, communication, banking, and finance. Given the critical role that they play in support of the functioning of our societies, a deep understanding of their actual capabilities to withstand natural and man-made hazards is crucial. The related issues of resilient network design and operation is also closely related to sustainability problems which are of increasing importance today. In particular, the degree to which a technological network subjected to internal or external stresses (e.g. cascading failures or seismic hazards) is capable of keeping (or recovering) the service demanded needs to be quantitatively estimated. A failure of a critical infrastructure to provide the required service could lead to a range of serious consequences for business, government and the community. In this respect, cascading failures, where external perturbations trigger some initial local failures that lead to eventual global network failure, are especially hazardous.
The main objective of this mini-symposium is to bring together experts working in the interdisciplinary area of critical infrastructures and network systems to present and discuss the latest developments in the field. Some relevant topics include reliability, risk, vulnerability and resilience analyses of critical infrastructures and network systems, modelling of technological networks, statistical properties of lifelines and processes on the networks (e.g. cascading failures).
