New Arithmetic Operations on Developed Parabolic Fuzzy Numbers and Its Application

In this paper, we have studied the basic arithmetic operations for developed parabolic fuzzy numbers by using the concept of the transmission average, which was already implied in [F. Abbasi et al., A new attitude coupled with fuzzy thinking to fuzzy rings and elds, Journal of Intelligent and Fuzzy Systems, 2015] in its rudimentary form and was nally presented in its fully- edged form in [F. Abbasi et al., A new and ecient method for elementary fuzzy arithmetic operations on pseudo-geometric fuzzy numbers, Journal of Fuzzy Set Valued Analysis, 2016]. The major advantage of these operations is that they ndings are closer to reality than extension principle-based fuzzy arithmetic operations (in the domain of the membership function) or interval arithmetic (in the domain of -cuts). A technical example is given to illustrate applying the method. The proposed method can model and analyze the fuzzy system reliability in a more exible and intelligent manner in comparison with the other methods.
