Using RiskVu as a Design Comparison Tool

The RiskVu computer program provides a high level interface to the FaultTree+ program allowing system designs to be compared by personnel with no experience in fault or event tree analysis methods.

What is RiskVu?

Fault tree and event tree analysis methods are widely applied to system availability and reliability problems in most engineering disciplines. They may be used to predict the performance of a system at various stages of the design process and indicate reliability weak spots in the design.

Experienced reliability engineers may modify the structure of the fault and event trees in order to compare predicted system performance from different design options. The computer program FaultTree+ is used by thousands of engineers to hold the fault and event tree data, analyze the system, and report on the results.

A detailed understanding of fault and event tree construction methods and the reliability logic for the systems being modeled is required to allow possible design changes to be reflected in the fault and event tree structures.

RiskVu provides a more controlled framework to compare and record design options and the predicted performance parameters.
