13. Fault Tree Logic Models
Jonathan L. Lucero, Timothy J. Ross · Society for Industrial and Applied Mathematics eBooks · 2002
Combining, propagating, and accounting for uncertainties are considered in this new extension of reliability assessment. Fault trees have been used successfully for years in probabilistic risk assessment. This scheme is based on classical (Boolean) logic. Now this method is expanded to include other logics. Three of the many proposed logics in the literature considered here are Lukasiewicz, Boolean, and fuzzy. This is a step towards answering the questions: Which is the most appropriate logic for the given situation, and how can uncertainty and imprecision be addressed?
