The resilience analysis performed in RESISTO follows an enhanced risk and resilience management process based on the ISO-31000 standard [1]. The main inputs needed for the resilience quantification are gathered at separate steps of the management process: a precise understanding of the system context and the system itself including all subsystems and components and their interconnections; a collection of all relevant system functions to quantify the loss of performance due to a disruptive event; a comprehensive list of potential threats and hazards including information about their effect on the system; a list of critical combinations of system performance functions and threats taking account of relevant resilience dimensions [2] not explicitly covered by the risk and resilience management process; a risk and resilience quantification of combinations found to be critical taking into account risk and resilience evaluation criteria; and finally a list of potential counter actions and mitigation strategies for the listed threats.
