FaultTree+ in Reliability Workbench

FaultTree+, the world’s most popular fault tree software package, is now fully incorporated into Reliability Workbench.

FaultTree+ is used around the globe to assess system safety in industries as diverse as Aerospace, Defense, Railroads, Automotive, Oil & Gas, Chemical Process and Nuclear Power.

FaultTree+ in Reliability Workbench is a powerful systems reliability analysis tool containing integrated fault tree, event tree and Markov analysis features. It can also be used in conjunction with Prediction, FMECA and RBD modules within Reliability Workbench.

Fault Tree Analysis

The FaultTree+ module in Reliability Workbench is the latest version of the world leading FaultTree+ software package. Isograph has built its reputation on the efficiency, accuracy, stability and ruggedness of its FaultTree+ product.

The FaultTree+ module provides an easy to use interface for constructing fault tree diagrams. Gates, events and failure models can be added with just a few clicks.

Fault tree diagrams represent hierarchies of sub-system and component failures and how they could cause system failures. The TOP event of a fault tree represents a system event of interest and is connected by a series of gates to component failures.

Failure and repair data is assigned to the system components. The Fault Tree module will perform a detailed analysis to calculate reliability and availability parameters for the system and identify critical components.

Event Tree Analysis

The Event Tree module is able to handle large problems and to fully handle success logic. An event tree model may be created independently of the fault tree model or may use fault tree analysis gate results as the source of event tree probabilities.

The event tree module handles both primary and secondary event trees, multiple branches and multiple consequence categories.

Markov Analysis

The Markov module allows users to easily build state transition diagrams and performs numerical integration to solve complex problems.

The models created in the Markov analysis module may be linked to basic events in the fault tree and event tree analysis modules.
