Basic Principles For Ships Performance Ranking Merit

摘要

With the aim to select best members from hull forms families, ships hydrodynamic performance data must be arranged so as to provide designers with some merit ranking lists allowing comparing performance variations against geometrical parameters variations. Usefulness of classifying ships performance parameters according to merit lists is discussed. More specifically, after stressing why it's never possible to construct rigorous merit lists completely fulfilling the similitude law, specific guidelines are given on how to usefully construct some appropriate approximate merit lists and virtual merit lists fulfilling the similitude law. The above guidelines are lastly applied in some specific sample examples.
