Multi-Disciplinary Computational Tools for Naval Design

Abstract

The general aim of Naval Design (ND) is to make a ship able to perform some prescribed mission. There is a combination of restrictions related to physical interaction of the warship and sea with others that have a military background. As a result, the ND combines numerous tasks and requires tremendous computations, but optimization of computations is a challenge because ND is a multi-criterion problem. This project delivers the complete succession of mathematical fundamentals of ND. Instead of traditional design spiral, a hierarchy multi-level design system is considered. The concept of criterion coordination with Lagrange multipliers is described. The feasible design solutions are studied with the Pareto sets. Comparison of Pruning and Constructive algorithms in grid generation is given, as well as description of LP-tay sequencing in this generation. The developed approaches are illustrated by examples of multidisciplinary ND recently considered in scientific publications. Additionally, a background of multidisciplinary trimaran optimization is developed.
