@ -754,11 +754,18 @@ Consider for instance an electrical circuit that has a TEST line.
|
||||
When the TEST line is activated, it supplies a test signal
|
||||
which will validate the circuit. This circuit will have two operational states,
|
||||
NORMAL and TEST mode.
|
||||
|
||||
It is natural to apply the operational states to functional groups.
|
||||
Functional groups by definition implement functionality, or purpose
|
||||
of particular sub-systems, and therefore are the best objects to model
|
||||
operational states.
|
||||
\paragraph{Inhibit Conditions}
|
||||
Some failure modes may only be active given specific environmental conditions
|
||||
or when other failures are already active.
|
||||
To model this, an `inhibit' class has been added.
|
||||
This is an optional atribute of
|
||||
a failure mode. This inhibit class can be triggered
|
||||
on a combination of environmental or failure modes.
