Abstract:
After demonstrating the feasibility of the inversion of a ship emission model with the CSP approach, we will now discuss about the optimization of emissions. In a first time, a single-objective approach with an aggregation function of the emissions will be used, then, it will be a multi-objective approach and the Pareto frontier will be computed. The objective of this paper is triple: first, to show that a full ship model, linking a propulsion model and an emission model, can be inverted. Then, to bring to light that a propulsion system can be sized by an approach minimizing the emissions and using an aggregate function. Finally, to demonstrate that, in this case, computing the Pareto frontier provides the same global optimum as the mono-objective approach.
