Fault Tree Analysis Training by Tonex

Fault Tree Analysis is a 2-day course where participants learn the ins and outs of FTA as well as basic concepts of system analysis.

Organizations turn to fault tree analysis (FTA) for a variety of benefits. For example, one important reason for constructing a fault tree diagram is to better identify measures and failures.

The fault tree explicitly shows all the different relationships that are necessary to result in the fault or failure. In constructing the fault tree, a thorough understanding is obtained of the logic and basic causes leading to the top event.

Using the logic of a detailed failure analysis and tools, FTA helps the team focus on the causes of each event in a logical sequence that leads to the failure. Furthermore, the countermeasures can be found out.

Many team leaders have also found fault tree analysis useful at providing an effective way to analyze the system. Other tools permit a way to explore system reliability, and FTA provides a tool that focuses on failure modes one at a time.

The fault tree is a tangible record of the systematic analysis of the logic and basic causes leading to the top event. Sometimes a shift in the frame of reference illuminates new and important elements of the system.

A popular added benefit of fault tree analysis is it creates a visual aid for system analysis and management. This works out well for organizations because it’s no secret that most managers prefer graphics to text.

Fault Tree Analysis can also be used by organizations that have a current design with modifications, which may include changes due to past failure – or when there is a current design being used in a new environment or change in duty cycle and no physical change made to the design.

An important benefit of FTA is how the analysis provides a unique insight into the operation and potential failure of a system.

This allows the development team to explore ways to eliminate or minimize the occurrence of product failure. By exploring the ways a failure mode can occur by exploring the individual failure causes and mechanisms, the changes impact the root cause of the potential failures.

Fault Tree Analysis Training Course by Tonex

Fault Tree Analysis is s a systematic method of system analysis and part of  operations research in system reliability and safety. Fault Tree Analysis (FTA) examines a system from top-down and provides graphical symbols for ease of understanding. It incorporates mathematical tools to focus on critical areas.

Fault tree analysis can also be also as an analytical technique for tracing the events which could contribute. It can be used in accident investigation and in a detailed hazard assessment. The fault tree is a logic diagram based on the principle of multi-causality, which traces all branches of events which could contribute to an accident or failure.

Participants in this course learn the concepts of Fault tree analysis as it is used a symbolic “analytical logic techniques” and its application in reliability and safety analysis. Learn  how basic events, often made up of failures at the component level, could lead to a hypothesized failure of a system.

Learn how fault tree analysis (FTA) is used in  system engineering and analysis practices such as reliability, maintainability and safety.  Using a failures analysis, you can attempt to determine the specific causes by constructing a logic diagram, a top-down approach:

• Identify potential causes of system failures before the failures actually occur (proactive)
• Evaluate the probability of the top event using analytical or statistical methods
• Efforts on improving system safety and reliability
