Abstract:

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