ToolKit Fault / Success Tree Module

Fault Tree analysis techniques continue to be adopted by a wide range of engineering disciplines as one of the primary methods of predicting system reliability and availability parameters. Fault trees may be used to analyze large and complex systems, and are particularly adept at representing and analyzing redundancy arrangements. In addition, common cause events are easily modeled.

The inverse of a Fault Tree, a Success Tree, can also be created using this module. In this case, all events are created using the "success" space rather than in the "failure" space of a traditional Fault Tree. A sibling of a Success Tree, an Attack Tree, can also be constructed to model the tools, capabilities, and events necessary for a successful attack on a facility, system, or other entity. Both approaches can be used for threat assessments and other analyses.

The ToolKit Fault Tree Module provides an environment, integrated with other safety and reliability techniques, within which to build and analyze fault / attack / success tree diagrams. This state of the art program makes use of the latest Microsoft® development technology to give you facilities that include Multi Document capability, paging, library facilities and direct links to the other ITEM ToolKit modules.

The Fault Tree Module uses efficient minimal cut set generation algorithms to analyze large and complex fault trees. Esary-Proschan, Rare, and Binary Decision Diagram analysis engines are all available together in one tool. NOT and Common Cause Failure logic may be included in the trees at any level.

Program features include:

Cut, copy and paste tree symbols
Creation and editing using drag and drop techniques
Multiple document interface
Allows bitmaps to be attached to a project
Library facilities for storing common data
Direct links to all other ToolKit modules
Customizable paging facilities
Export results in CSV, delimited text and fixed field length formats for importing into Microsoft® Access®, Excel® etc.
Fully customizable reports, graphs and charts
Features common to all modules

Binary Decision Diagram analysis technique (BDD) is also available. Click here for full details.
