General principles

Feared events library

The feared event library contains all the feared events for the current system. It's recommanded to define them in the upstream steps of the safety analysis.

This library is unique for each project. However, it's possible to duplicate a library content from a project to an other, using the library import mechanisms. See : feared events library import

Feared event

A feared event can be caused by a failure in the analysed system. The feared event is not the failure itself, but the failure consequence. Thus, the feared events are not specific to one analysis, and can be in common between several systems.

Feared events family

A family is an arbitrary group of feared events and families. The creation of a family can be useful when several feared events have common effects for example, and it eases the propagation as this one can be done on a family directly. Moreover, a feared event can be referenced by several families, or even none.

References deletion

When a feared event or a family item is deleted, all its references are also deleted.

This includes :

Reference cycles

In the library structure, it's not allowed to make cycle between any families or feared events. A cycle corresponds to the case where, without any depth limit, a family appears in its own referenced item.
