Abstract:It is studied to design the ship waterline with as few NURBS (Non-Uniform Rational B-Spline) control points as possible, based on the geometric properties of the waterplane. The appropriate multi-objective constrained optimization model is set and an adaptive genetic algorithm (AGA) is applied to solve the optimization problem. The instances of the typical waterlines design for full-scale ship indicate that it is feasible and can satisfy the engineering precision to design the waterline applying this method and the data used for waterline representation can be reduced. So it is expected to design a bull surface with as few data as possible.
