Fault-Tree-Analysis<\/a> (FTA) is a type of systems analysis of technical systems.<\/span><\/span> It is based on Boolean algebra to determine the probability of failure of a system or an entire system.<\/span><\/span> Depending on the application, FTA is standardized in various areas, e.g., as the international standard IEC 61025 (EN 61025).<\/span><\/span> <\/a><\/span><\/span><\/span><\/p>\n

Visual-XSel 20 Analyser<\/a> allows you to create fault trees quickly and easily.<\/span><\/span><\/span><\/p>\n

Principle structure of the FTA<\/span><\/span><\/span><\/h3>\n

The Fault-Tree-Analysis is structured vertically.<\/span><\/span> At the top is the so-called Top-Event, the result of the Basis Events at the lowest level, the actual triggering causes.<\/span><\/span><\/span><\/p>\n

Aim and benefits of the FTA<\/span><\/span><\/span><\/h3>\n

The goal is to determine possible combinations of causes that lead to certain undesirable events, the Top-Event. The FTA is therefore also a risk analysis.<\/span><\/span><\/span><\/p>\n

FTA is primarily a preventative method, but is also used as an analysis tool in the event of a failure.<\/span><\/span> Other characteristics of FTA include:<\/span><\/span><\/span><\/p>\n
