Fault tree analysis improvements: A bibliometric analysis and literature review

Fault tree analysis (FTA) is one of the most popular failure techniques that reveal potential pathways leading to systems or components failure. It has been widely employed in numerous sectors understand how a system fails and improved. However, conventional FTA criticized due series inherent shortcomings state arts. Accordingly, scholars, engineers, practitioners made their attempts improve by dealing with its critical deficiencies over last decade. few works have performed review synthesize relevant studies on improvement topics. Thus, present study aimed carry out systematic literature state-of-the-art theoretical empirical findings concerning from 2011 2021 using Scopus database collection. In this sense, an in-depth investigation conducted statistical metadata analysis. This subject discusses frontier directions development trends research status. addition, bibliometric undertaken ascertain productive influential researchers, centers, hotspot fields. also sheds light existing literature, evolution topics, opportunities. The outcomes work highlighted annual publications topics are significantly growing, especially after 2019. Besides, Jianxiu Wang, Yan-Feng Li, Yihuan Wang productive, prolific, highly cited authors worldwide; Asia, particularly China, contributor area. According Bradford's law, one-third all (7995) field published 40 sources. Finally, “Decision-making,” “Risk analysis,” “Uncertainty Analysis,” “Bayesian Networks” four major hot integrated into improving FTA.
