Optimization

Finally, optimization. It is the conclusive step in the design process and the supreme discipline.

Feed the optimization with your selection of most promising variants and the FRIENDSHIP-Framework has strategies to hone them and to make them optimally suitable for their operational task.

These strategies are optimization algorithms. Mathematical operations, which aim at either a single objective or at a number of them. For instance, Brent, Nelder-Mead Simplex, Tangent Search, NSGA-II Genetic Algorithm, Multi-Objective Simulated Annealing. Framed by equality and inequality constraints, which you can define and which the system respects, they guide you to the most suitable design.

The results you achieve through optimization within the FRIENDSHIP-Framework are convincing. On average, you achieve a 5 percent improvement in energy efficiency for a ship hull. This can be translated in several USD 100,000s per year for fuel costs, which are saved or spent, depends on where you are with your design.

For a practical use case, please check our case studies. For your own calculation on savings please consult the Fuel Savings Calculator by our colleagues from GL's FutureShip.

Parametric modeling, variation and optimization may well resemble the key design steps. They are, it goes without saying, embedded and complemented by a full range of functionality.
