AutoFTAIt is a fault tree modeling and analysis software. AutoFTA uses a graphical drag-and-drop method to build a system fault tree, supporting eight commonly used logic gates such as OR gates, AND gates, NOT gates, and voting gates. It has functions such as minimum cut set analysis, minimum path set analysis, event probability analysis, bottom event or conditional event importance analysis, etc. It integrates two algorithms, precise probability analysis and Monte Carlo simulation, and displays analysis results in tables or graphics. It integrates fault tree modeling, analysis operations, and result display on a graphical integration platform, which can meet the actual engineering needs for fault tree analysis. Huajun Software Park provides you with free download of AutoFTA. Friends who like AutoFTA come to Huajun Software Park to download and experience it!
(1) Fault tree modeling
Supports 8 types of logic gates, including AND gate, OR gate, NOT gate, voting gate, XOR gate, sequential AND gate, forbidden gate, and transfer gate. It supports the independent subtree analysis function of intermediate events to facilitate the modular decomposition of complex fault trees.
Customization functions of fault tree graphics, such as bottom event sequence, graphic size, color settings, text attributes, automatic alignment, etc., support copy and paste of subtrees.
(2) Qualitative analysis
Analyze the minimum cut set or minimum path set of the fault tree. If the occurrence probability of the base event and conditional event is input, the occurrence probability of each minimum cut set or minimum path set will be automatically calculated to provide a reference for formulating the fault diagnosis sequence.
(3) Quantitative analysis
Supports two quantitative algorithms, the binary decision diagram method and the disjoint algorithm, to analyze the occurrence probability of top events and intermediate events, and the structural importance, probability importance and relative probability importance of bottom events or conditional events.
Quantitative analysis supports re-entering the probability of occurrence of bottom events or conditional events without changing the fault tree, ensuring good reusability.
(4) Monte Carlo simulation analysis
In view of the situation where it is difficult to use accurate algorithms for very large fault trees, Monte Carlo simulation is used to analyze the occurrence probabilities of top events and intermediate events.
