A fault tree analysis (FTA) is a risky method of analysis, describing how a plant hazard or other undesirable event may occur in terms of combinations of individual nonhazardous component or operator failures. From: Fire Pump Arrangements at Industrial Facilities, 2017 ...
The following extensions of fault trees, non-coherent fault trees, fault trees with delay and multi-performance fault trees, are also explained. Traditional algorithms for fault tree analysis are presented, as well as more recent algorithms based on binary decision diagrams (BDD)....
Fault tree analysis(FTA) was adopted to diagnose the fault of hydraulic system in automobile crane. 介绍了利用故障树分析法对汽车起重机液压系统进行故障诊断的方法,以该液压系统"放下支腿,车体无法支起"的典型故障为例,通过建立故障树,对其进行了定性分析,并介绍了应用故障树查找故障的方法。 2. In order...
In this paper the fault tree analysis is introduced and a possible application of that method is shown using a small computer network as an example. The constraints of this methods are explained and conclusions for further research are drawn....
We propose to use fault-tree analysis to determine how certain undesirable states can occur in a system. The results of the analysis expressed in terms of duration calculus formulas are integrated with state chart-based specifications. As a result, we obtain a testing model that provides a ...
Fault Tree AnalysisDesign Structure MatrixFunctional ModelingSafetyIncreasing complexity of products and safety regulations combined with an increasing amount of variants complicates the process of safety analysis within systems engineering. Moreover, it is known that the early avoidance or prevention of ...
We refer to this scheme as the tree edge f-FTC labeling scheme. Our tree edge f-FTC labeling scheme is implemented with two other labeling schemes, respectively referred to as the ancestry labeling scheme and the S-outdetect labeling scheme (explained in the next section). The second ...
In this paper, a gradient boosting tree model is proposed to detect, identify and localize single-phase-to-ground and three-phase faults in low voltage (LV) smart distribution grids. The proposed method is based on gradient boosting trees and considers branch-independent input features to be gen...
Binary Decision Diagram (BDD) based fault tree analysis algorithms are among the most efficient ones. They allow performing exact probabilistic analyses, as well as to derive a Zero-suppressed BDD (ZBDD) to efficiently encode Significant Prime Implicants (PI) or Minimal Cut Sets (MCS). The pre...
Bearing Fault Diagnosis Based on Dual-tree Complex Wavelet Transform A novel method of bearing fault diagnosis based on demodulation technique of dual-tree complex wavelet transform (DTCWT) is proposed. It is demonstrated th... H Li - International Conference on Mechatronics & Intelligent Materials ...
