Fuzzy reliability evaluation using conflicting bifuzzy approach

The increasing demand for electrical and electronic systems has been driven by a number of application categories. The manufacturers are generally interested in improvement in performance and life of the system without loss of its reliability. Therefore, it is worthwhile to carefully estimate the reliability of the system. We know many times in real life situations, it is difficult to obtain the complete and clear information for a complicated system so decisions for the system are made on the state of uncertainty. To handle these types of situations the concept of fuzzy theory was introduced. But there are instances where fuzzy information can also show uncertainty which can be dealt with the concept of conflicting bifuzzy sets. In this study fuzzy reliability of systems has been analyzed considering the reliability of the components as conflicting bifuzzy sets. Methods have been developed to calculate the fuzzy reliability of different types of systems.
