The guidance law generates an angle of attack control command that satisfies the terminal constraints (considered as hard constraints) and the path constraints (considered as soft minimizable constraints).
Strength requirements are also considered as constraints within the optimisation.
Water and land availability, capital and non-negativity were considered as constraints (scenario 1).
Due dates are considered as constraints in the problem, that is, tardiness is not allowed.
The boundary and initial values of ODEs are considered as constraints for the optimization model.
In the proposed unit commitment model, the two indices are considered as constraints.
Operational considerations, such as minimum harvest levels, can be important, and are considered as constraints in this modeling process.
The aim is to reach maximum availability, considering as constraints installation and corrective maintenance costs, weight and volume.
Specified performance objectives are considered as constraints and their variance over the obtained Pareto front is investigated.
In fact, only one objective function is selected in each state and others are considered as constraints.
