A New Method of System Reliability Evaluation Based on the Fuzzy Theory

The system reliability is determined by both failure mode and reliability of system units. Therefore, the assessment of system reliability must firstly be depended on the assessment of the reliability of system units. In the same reliability system, the system reliability performance will be affected by the composition of different system unites. In response to this problem, a new method of system reliability evaluation was proposed in this paper. The method considers the system reliability and the reliability of system units, so the assessment of the system reliability will be more comprehensive.
