Simulation software

Assign objectives of reliability / availability

Context

Within the safety studies, it is necessary to examine the succession of failures leading to undesirable events, (fire, explosion, mission loss, …), the analysis via a fault tree has to be used in such a case.

Software tool

FaultTree module from itemToolkit software tool.

Capacity

This module allows the analysis via a fault tree. It enables to determine the minimal cut sets and the factors of characteristic importance of the studied tree. It uses different calculation engines allowing an accurate assessment of the failure combinations.

Modularity

The import of data taken from other modules, (MIL HDBK, RDF2000,…; RBD…), allows to pre-constitute fault trees.

 Results

A report, which can be parametered according to the desired data, can be generated. It can be exported towards the most widespread software suites.

Analysis via a fault tree  :

The fault tree is one of the major tools in the analysis of technological risk, developed in the early 1960's in the United States. It is a deductive and arborescent method, allowing a qualitative and quantitative processing. It is used to calculate the probability of a system failure in the absence of information about an actual case. Therefore, it can be applied to technological processes with scarce failures, in the case of new processes and, consequently, it can be used in the frame of a preliminary environmental assessment. The use of the fault tree requires a good knowledge about the studied system. In this context, the analyst can rely on a method of hazard identification such as the FMEA which will give him the required knowledge about the system functional mode.
