The guarantee for the reliability of systems in the design of engineering systems is one of the important issues. The reliability of the engineering systems can be analyzed by evaluating the reliability of the entire engineering systems after calculating the reliability in each method by reflecting the sequential or parallel components of the subsystems. In this study, we propose the method for analyzing the reliability of the engineering systems using type-2 fuzzy sets. Since type-2 fuzzy sets represent the fuzzy set as the three dimensional, it is possible to represent more various shape of fuzzy sets than the conventional fuzzy sets-fuzzy sets, intuitionistic fuzzy sets, vague sets, level (λ,1) interval-valued fuzzy sets, neutrosophic sets, octagonal intuitionistic fuzzy sets, polygonal type-1 fuzzy sets, etc-. In addition, since the degree of membership is represented as the secondary grade which may take any value from unit interval [0, 1], it becomes possible to express the degree of membership more flexible than the type-1 fuzzy sets that represent the reliability as one real number. And then it accepts the two assumptions based on the possibility measure of fuzzy reliability engineering, it has theoretical bases for using type-2 fuzzy sets to evaluate reliability. The proposed method of obtaining the reliability based type-2 fuzzy sets can be applied to fuzzy engineering systems, fuzzy decision making systems, fuzzy reliability engineering, fuzzy inference systems, etc. |
