Fault tolerance and resilience: meanings, measures and assessment

Strigini, L. (2012). Fault tolerance and resilience: meanings, measures and assessment. In: Wolter, K., Avritzer, A., Vieira, M. & van Moorsel, A. (Eds.), Resilience Assessment and Evaluation of Computing Systems. . Berlin, Germany: Springer.


To assess in quantitative terms the “resilience” of systems, it is necessary to ask first what is meant by “resilience”, whether it is a single attribute or several, which measure or measures appropriately characterise it. This chapter covers: the technical meanings that the word “resilience” has assumed, and its role in the debates about how best to achieve reliability, safety, etc.; the different possible measures for the attributes that the word designates, with their different pros and cons in terms of ease of empirical assessment and suitability for supporting prediction and decision making; the similarity between these concepts, measures and attached problems in various fields of engineering, and how lessons can be propagated between them.
