The Component Importance of Complex System Based on Bernoulli State Variables


Article Preview

Complicated structure of complex system makes it difficult to analyze and evaluate its reliability. Here we propose a method to calculate the importance of complex system components using a technique of Bernoulli State Variables (BSV). The models of three reliability importance, which describe the importance of each component, are proposed. Our studies show the method is suitable for complex artificial systems, and we proved the method can be used for maintenance decision and failure diagnosis though an example.
