Research on the Improvement of Fault Tree Analysis

摘要

With the legalization and systemization of safety production, safety evaluation has become an important measure in the construction project. For the sake of the probing and researching to the method of safety evaluation that will perfect the existing evaluation methods to establish a better and more practical and scientific safety evaluation system. The merits and shortcomings as well as the main improvement directions of fault tree analysis (FTA) have been pointed out after the detailed analysis. According to the characteristics of the FTA and the basic knowledge of fuzzy mathematics, not only the five amendatory scheme of FTA with the method of setting up subjection degree are put forward, but also the rationality and science of the improved FTA is stated through the demonstration of theoretical analysis and practical examples.
