Abstract:

According to the structure of system and the reliability of components, how to analyze quantitatively system reliability is one of the important problems in reliability engineering. The methods of system reliability are summarized, and these methods are divided into analytical method, Monte Carlo method, the comprehensive method and the network method. Advantages and disadvantages of the four methods are analyzed and their application ranges are discussed. Finally, combined topological structure with reliability properties, new reliability measures are presented to evaluate system reliability, which is outlined as possible future directions.
