e1ns.ftaRecognize impacts.

Determine the probability of occurrence of system failures with PLATO e1ns.fta. It is an ideal tool for both qualitative and quantitative fault tree analysis.

A special feature of PLATO e1ns: The existing system model provides basic data for the fault tree analysis. New findings from the analysis automatically flow back into system architecture and thus into other analyses. With this unique method integration in PLATO e1ns, fault tree analysis can be integrated into FMEA, MSR and FMEDA*.

*PLATO e1ns FMEDA is certified according to ISO 26262.

PLATO e1ns is the web-based Product Innovation Platform for the optimal design of the product development process.

Model-based, visual, consistent, agile, simple, scalable, and globally available.

e1ns.ftaFor a quick and informal problem analysis.

One of the major challenges in product and process development is to improve system safety and reliability. The key to this is Fault Tree Analysis (FTA). It identifies the events and their combinations that can cause a system failure and calculates estimates of the system's probability of failure. The systematic design of system and function structures is a good basis for this method.

PLATO e1ns.fta enables an assessment of risks and reliability of complex systems and processes. Thereby the e1ns system model and the function and failure nets are the basis for the FMEA and the fault tree. With this tool, failure causes are assigned to a main event. Everyone involved quickly gets an overview of the causes and combinations of causes that can lead to an undesired event.

Scope of Functions:

  • Qualitative Fault Tree Analysis (excluding probability calculation)
  • Qualitative Fault Tree Analysis (including probability calculation)
  • Probability calculation
  • Determination and evaluation of minimum cuts to determine their probabilities
Reuse Knowledge and Reduce Effort

The template concept of PLATO e1ns provides a Fault Tree Analysis for variants or similar products and projects. The complete (generic) fault tree is available with all calculations, only individual adjustments have to be made.

Hand in Hand with the FMEA

The system model and the function and failure network are the basis for the FMEA and the fault tree. Newly detected faults are used for the FMEA, if required they can also be used exclusively for the Fault Tree Analysis.


Interaction with Functional Safety

PLATO e1ns.fta interacts with FMEDA method and safety function analysis (monitoring, response). When creating Functional Safety Analyses, the FIT values are displayed at the basic events in the tree.

FMEDA and PLATO Functional Safety

Suitable for two types of Fault Tree Analysis.

Qualitative Fault Tree Analysis

In this analysis, fault correlations are systematically considered over any number of system and process levels. Events and event combinations that lead to the respective main or intermediate event under review can be traced in the Fault Tree Diagram. However, a reduced minimal solution set containing the essential combinations of faults is sufficient for fault analysis. This essential subset is called minimal cut.

Quantitative Fault Tree Analysis

In addition to the fault correlations, this analysis also takes probabilities into account. If the probabilities of all individual failure causes are known, the probabilities of occurrence can be calculated for the main or intermediate events analyzed. In the case of technical analyses, data on the failure behavior per time interval (FIT) can also be included. FIT describes the failure rate of technical components (e.g., electronic components) over a period of "one billion hours.
