ITEM ToolKit Fault Tree software incorporates two independent calculation engines: Binary Decision Diagram and Approximation Method. Switch over to ITEM ToolKit Fault Tree BDD Engine today to analyze your trees quickly, efficiently and most importantly with EXACT PROBABILITIES. When it comes to SAFETY, don't settle for Approximated Probabilities. The analyses take seconds instead of hours, giving me accurate results that I can rely on. Using ITEM ToolKit BDD engine has resolved this issue dramatically and completely. "With my previous software, the analyses of my large fault trees were taking forever and finally running out of memory and crashing. Now I'm getting results that finally make sense!", S.D., SAFRAN "I didn't realize the benefits of the Binary Decision Diagram (BDD) engine for analyzing Non-Coherent fault trees until I switched over to this solution in ITEM ToolKit. Numerous companies are switching over to ITEM ToolKit as their trees become larger due to the inefficiency of their previous software tool.

Only ITEM ToolKit offers a unique flag at system level to switch between the traditional approximation method and binary decision diagram analysis.Īrrange for a Web Demonstration today to see the full benefits of ITEM ToolKit to your Organizational needs Approximation methods cannot be used to accurately solve "non-coherent" fault trees. Only by using a BDD engine to solve trees such as these can offer you exact results.

Only ITEM Software can offer you the unique solution for these complex Analyses problems: Binary Decision Diagrams (BDD).

Are your current Fault Trees "Non-Coherent" Fault Trees?.

Are your current Fault Trees too complex to be analyzed by traditional Approximation Methods?.

The Quantitative analysis of the Fault Tree focuses on the probabilities of system and cut set failure or the occurrence of the top event based on the probabilities of failure of the basic events. The Qualitative analysis of the Fault Tree determines the: a) probability of system failure (top event) based on a single failure (basic event) cause or common cause potential using minimal cut sets, b) combination of component failures (minimal cut sets), c) importance ranking of contributors to system failure. As Fault trees are constructed, the Boolean equations are used to evaluate the Quantitative and Qualitative characteristic of a critical system. The Boolean methodology and equations are used to construct and simplify the Fault Tree. Additionally, Fault Tree Analysis can help prevent failures from occurring by providing you with data showing how and under what circumstances the failure could occur, allowing for alternative measures to prevent (or design out) the catastrophic failures or hazards. Using this detailed information, efforts to improve system safety and reliability can be highly focused and tailored to your individual system by using the quantitative results from the data you input. Often times, Fault Trees are used in reliability and safety risk assessments to represent graphically the logical interactions and probabilities of occurrence of component failures and other events in a system.Ī Fault Tree Analysis identifies and ranks combinations of events represented on a Fault Tree that cause system failure, and provides estimates of the system's failure probability. Using failure probability and system reliability data can assist you in addressing the undesirable events or challenges.

These challenges are more compounded where manual methods of fault isolation and risk analysis in large and complex systems are not viable. To improve system safety and reliability, designers and analysts have to make better-informed risk assessment decisions based on quantified evaluations of the risks and effects associated with alternative designs and other risk-mitigating actions. To address safety and the ways failures or undesirable events could occur and thereby, trying to avoid them can be very challenging. Fault Tree Analysis uses tree structures to decompose system level failures into combinations of lower-level events, and Boolean gates to model their interactions.
