<p>A computer implemented method of optimising the design of an engine in a collaborative optimisation environment having a system level constraint to be met and a plurality of subsystems with one or more local constraints to be met. One of the local constraints to be met is the actuator change between a plurality of subsystem points. The method comprises identifying a system level constraint, such as fuel efficiency, to be met by the engine optimisation; passing the system level constraint to be met to the plurality of subÂsystems and optimising a plurality of the sub-systems according to the system level and local constraints. The local constraint of actuator change between a plurality of sub-system points is defined as a minimisation in actuator change (local smoothness) between a plurality of sub-system points.</p> |
