Disclosed is a system for analyzing a static fault tree from a system model.

Open-PSA defines an XML formalism to describe a fault tree.

Other techniques, including fault tree analysis and failure mode analysis, are discussed elsewhere in this Encyclopaedia.

Figure 2 shows a simplified example of a fault tree for the failure of a pump at a coal terminal.

Other techniques, including fault tree analysis and failure mode analysis, are discussed elsewhere in this Encyclopaedia.

This may be based on a Failure Mode and Effect Analysis (FMEA), a Fault Tree Analysis (FTA) or any similar process appropriate to system safety considerations.

Fault tree analysis diagrams are commonly used to illustrate events that might lead to a failure so the failure can be prevented.

A fault tree is a graphical representation of all the basic events that can cause an undesired event in a process or system.

Fault tree analysis is useful both in designing new products/services (test cases for new components) or in dealing with identified problems in existing products/services.

Fault tree analysis diagrams are commonly used in Six Sigma processes, particularly in the Analyze phase of the Six Sigma business improvements process.

Depending on the level of accuracy needed, the Bool module allows you to detail a component (such as a block) using another model (a Fault Tree, for example).
