概要

論文の詳細を見る
In the previous paper, the authors obtained the simplified method of strength evaluation for double bottom structure by using energy method in consideration of various boundary conditions in terms of Lagrange's multiplier. The optimization of hull weight for bulk carrier by the Genetic Algorithms (GA) is investigated in the present paper. The scantlings of structural members are determined by classification rules and the strength levels evaluated by the simplified method in the previous paper. The conditions of constraint are not provided in the optimization since the scantlings are given so as to satisfy the allowable stress confirmed through the stress calculation and the conditions such as spacing, span length and so on.
