A Fuzzy Set Approach to Vulnerability Analysis.
Abstract
This document illustrates how vagueness or uncertainty can be modeled by fuzzy sets and how this uncertainty is reflected in the final measure of vulnerability. Its emphasis will be on the computation of vulnerable area of a surrogate system with uncertainty present in the cell probabilities. The uncertainty in the cell probabilities can be attributed to uncertainty in assigning component kill probabilities, to error in engineering judgement in determining critical areas of components and component kill criteria and to unknown synergistic effects. Other contributions to uncertainty are of course present, starting from the target description through a myriad of subjective decisions and engineering judgements inherent in the vulnerability analysis. For the purpose of completeness and comparison, a point estimate of the vulnerable area of the surrogate system will also be determined as it is currently done in vulnerability analysis. A point and interval estimate of the vulnerable area will be determined by a statistical procedure known as bootstrapping. Finally, a fuzzy vulnerable area will be calculated and the different approaches compared. (Author)
