Event-tree analysis by fuzzy probability

Fuzzy logic for process safety analysis

“…The foundations of fuzzy logic systems design are already well established (Dubois & Prade, 1980). The use of fuzzy logic (FL) in different aspects of safety and reliability analysis has been discussed in a number of papers (Bowles & Pelaez, 1995;Gentile, Rogers, & Mannan, 2003;Geymar & Ebecken, 1995;Karwowski & Mital, 1986;Kenatrangul, 1991;Kim, Ju, & Gens, 1996;Markowski, 2006;Misra & Weber, 1990;Quiech & Cameron, 1994;Singer, 1990;Solzano & Cozzani, 2006). There is no paper on fuzzy ''bow-tie'' although there were some works on a separate use of the fuzzy sets in a fault tree (Geymar & Ebecken, 1995;Kim et al, 1996;Singer, 1990) and an event tree (Kenatrangul, 1991;Markowski, 2006).…”

Fuzzy logic for piping risk assessment (pfLOPA)

“…The use of fuzzy logic (FL) in different aspects of safety and reliability analysis has been undertaken in a number of papers (Bowles & Pelaez, 1995;Geymar & Ebecken, 1995;Karwowski & Mital, 1986;Kenatrangul, 1991;Kim, Ju, & Gens, 1996;Misra & Weber, 1990;Quiech & Cameron, 1994;Singer, 1990;Solzano & Cozzani, 2006). It is clear that after nearly thirty years of research, fuzzy logic has proven its worth as a practical engineering and problem-solving tool.…”

Bayesian reliability analysis for fuzzy lifetime data

“…However, with the progress of modern industrial technologies, product development cycle has become shorter and shorter while the lifetime of products has become longer and longer. As a result, it is time consuming, expensive, and sometimes impossible to obtain many observations [24,30,37]. In many engineering applications, there may be very few available data points, sometimes only one or two observations.…”
