Abstract:

In order to accurately grasp the evolution law of reliability index of the complex multi-state system and its components, it is necessary to carry out dynamic reliability analysis. A dynamic reliability analysis method for complex multi-state system considering epistemic uncertainty is proposed to deal with the epistemic uncertainty caused by small samples, inadequate failure data which are difficult in obtaining and uncertain failure or degradation mechanism. Based on the GO method, this paper constructs a multi-state GO operator considering epistemic uncertainty combining evidence theory to quantify the uncertainty of the complex multi-state system, and models the reliability of the complex multi-state system combining the Markov model. The feasibility of the method is verified by an example.

Key words: complex multi-state system, GO method, epistemic uncertainty, evidence theory, dynamic reliability analysis
