A new approach for analysis the fuzzy reliability using LR type interval valued flat vague set

Abstract

This paper describes a vague sets-based fault tree technique to evaluate the reliability indices for power plant systems. Due to uncertainty in the collected data, all failure probabilities of the components of the system are represented by LR type interval valued flat vague sets. For preserving the shape of the LR type interval valued flat vague sets T ω -based arithmetic operations are used. An example of gas power plant is given to demonstrate the method described in this paper. By using this approach, the fuzzy system reliability can be analyzed in a more flexible and intelligent manner.
