Bayesian-based information extraction and aggregation approach for multilevel systems with multi-source data被引量：4
《Journal of Systems Engineering and Electronics》2017年第2期385-400,共16页Lechang Yang Jianguo Zhang Yanling Guo Qian Wang 
supported by the National Basic Research Program of China(973 Program)(2013CB733000)
The ever-increasing complexity of industry facilities has made the reliability analysis and assessment an imperative yet tough work. Motivated by practical engineering requirement, this paper develops a Bayesian-based...
