基于信息融合技术的多阶段可靠性评估方法研究

Research on the Method of Multistage Reliability Assessment Based on the Information Infusion Technology

通过对信息融合技术的分析和实践,论证了其在可靠性评估过程中的巨大潜力。通过引入变化因子,以及对Bayes方法在多阶段可靠性数据融合过程中所存在的缺陷做出分析,对不足进行了改进,使运用Bayes方法进行复杂系统可靠性评估的可信度提高。最后通过实例证明了该方法的可行性和有效性。

Through the analysis of information infusion technology, the paper proved the great potential functions has in the process of reliability assessment. By using the change factor, and analyzing the limitation that exist in the process of reliability assessment with the Bayes method, the shortcoming has been fixed. Then the reliability of the evaluation was in- creased when the Bayes method was used in the process of multistage information infusion. Finally, the feasibility and validi- ty of this method were proved by some examples.
