|The simulation model
is designed in six parts. The crew
participates in all six areas with the commander having final action
power. (Carlino, 1986)
|1.Mission Requirements – the requirements entered into the
system and the perceived environment sent via sensors forms the basis for all
decision making. The underlying design
concept is to provide the ability to crew members to recover from subsystem
failures in real time and to asses threats from the outside.
|2.Information processing – The main processor uses an
algorithm to check the availability of the subsystems and to evaluate their
importance in case of failure. A
matrix comprised of N subsystem columns by M user-operator rows is evaluated
with a weight given the failure’s importance.
|3. Once a failure is evaluated, a message is sent to the
operator with a recommended action.
The command chain then evaluates the recommendation and the final
action is selected.
|4. The action system is fed the corrective action and the
matrix is reevaluated. The actions are
entered until the alarm state is removed.
|5. Sensors are used to monitor ship performance and
environmental factors such as outside threats or found targets.
|6. Threat/ Targets – Once identified through the sensing
devices, decisions on proper actions are fed into the action system. Threats and targets can then be dealt with
