Staging allows to reduce a launcher's gross mass by jettisoning the empty stages once their propellant has been consumed. The design choices concern the number and dimensions of stages, the type of propellant, and the structural technologies. Staging optimization aims to find the minimum cost launcher compliant with a set of specified missions defined by orbits and payload masses. This problem is generally addressed by iterative methods (successive steps of design and trajectory optimization), but it can also be solved directly by a coupled method using a simplified command law. The coupled approach allows the optimization of versatile configurations and it can account for margins suited to the model uncertainties associated with preliminary design phases.
