Abstract: While accepted as part of critical infrastructure (CI) resilience, no consensus exists on how to measure the exact
minimum level of service or the rapidity of rapidly restoring services. The H2020 European project IMPROVER
(Improved risk evaluation and implementation of resilience concepts to critical infrastructure) suggests to use the
public?s declared tolerance levels for both minimum level of service and rapidity of service restoration as criteria
with which to evaluate if the resilience of a given CI is resilient enough. This paper demonstrates the development
of a questionnaire-based methodology to determine public tolerance levels. It then tests this methodology via a
pilot case study at IMPROVER?s Hungarian Highway Living Lab. The paper argues that public tolerance levels
are a reasonable choice for resilience evaluation criteria and demonstrates that the questionnaire-based
methodology permits one to evaluate public perception in such a way as to compare it to technical resilience
analyses.

Thomas Münzberg, Marcus Wiens, & Frank Schultmann. (2015). The Effect of Coping Capacity Depletion on Critical Infrastructure Resilience. In L. Palen, M. Buscher, T. Comes, & A. Hughes (Eds.), ISCRAM 2015 Conference Proceedings ? 12th International Conference on Information Systems for Crisis Response and Management. Kristiansand, Norway: University of Agder (UiA).
Abstract: Coping capacities (CCs) are often implemented at Critical Infrastructure (CI) facilities to ensure a continuous supply of vital services and products for a population during lifeline disruptions. Through various restrictions, these redundant backups are frequently limited and, hence, only allow a supply continuity for a short duration. The capacity depletes with the duration of the disruptions. In this paper, we discuss how this decrease is evaluated in disaster management. To get an enhanced insight, we introduce to a representative decision problem and used a demonstrative example of a power outage to discuss how decision maker consider the effect of CC depletion and how analytical approaches could address this issue. For doing so an expert survey and an analytical approach were implemented and applied. The comparison and the discussion of the results motivate further research directions on this topic.
