Safety assessment, reliability, and the probability-operation diagram

Cooperative decision making in a knowledge grid environment

“…In order to solve the equation set crePoss o AssCreM = crePoss, the fuzzy Markov chain model [10] is used. Since AssCreM is a fuzzy transitive matrix, crePoss should be an eigen-fuzzy set.…”

“…In other words, such propagation of credibility confirmation is a desired property. In order to determine source credibility, many approaches such as probability theory [10], Bayesian theory [2,3] and possibility theory [4,6] can be used. Considering the nature of vagueness in knowledge grid environments, mainly caused by the lack of knowledge rather than the randomized functionality of the system, the use of possibility theory for the modeling of these systems seems to be more appropriate than probability theory.…”

Power system safety management and audit protocols

“…An independent safety-assessment (especially when a topdown method is used) shows the proper information which must be collected by an accident investigation as well as during usual system-use, and stored in a data-bank so that an acceptable system-safety monitoring function can be carried out [8].…”
