摘要：This paper presents reliability analysis for components using fuzzy operations. Probability assumption and Fuzzy State assumption (PROFUST) reliability theory is used to find out the reliability of each system component. Here, the reliability of each system component is presented by trapezoidal fuzzy number. The proposed method is used to simplify fuzzy arithmetic operations of fuzzy numbers. Finally, a numerical example is illustrated to verify the efficiency of used operations in the functions.
