Reliability Modeling applying Fuzzy Logic

Utilizing the fuzzy logic has already been put into practice in the operational process of the machines . Since the function of these machines depends on their failure condition , utilizing the fuzzy logic in reliability engineering of machines ant their operations is also unexpected .
Since now , the investigations have been done according to the fitnees of different reliability functions on the basis of binary logic , and the machines were considered either completely active or completely out of order . But the mal functional conditions between these two conditions have not been significant , although these conditions especially in mechanical machines are inevitable . This paper with a simple attitude towards thd fuzzy logic , uses it in estimating the related reliability functions and has also introduced concepts of accuracy , the belief of probability and the truth of the reliability greater in these conditions .
