Evaluating fuzzy reliability using rough intuitionistic fuzzy set

Fuzzy set theory has been studied extensively over the past several decades. It has been applied to solve many real life problems including system reliability. In this paper we define rough intuitionistic fuzzy sets with their properties and present a new method for analyzing fuzzy reliability of different types of systems considering the reliability of the components as rough intuitionistic fuzzy sets for handling the vagueness and incompleteness in information.
