Gates guidelines
Functions
Station gates prevent deviations from
operational procedures, by delaying and preventing the execution of
erroneous actions, as follows:
- Potential deviations from the
rules are detected prior to their execution,
by checking the action compliance.
Instead of direct execution, the
station is notified about the deviation from
the rules, enabling the
operators to regret.
- If a command complies with the
operational rules, it is transmitted
to the functional unit right away.
- Otherwise, if the command does not comply with the
operational rules,
then its execution is suspended.
- When a potential deviation is detected, the
gate notifies the
corresponding
station about it, enabling the
operator to double check and
then either confirm
that the action is indeed as intended, or to cancel it otherwise.
- Only after the
operators confirm that the action is according to their
intention, it is executed.
Interaction styles

The interaction style, should be
suited to the corresponding
