Optimum Preliminary Ship Design Technique by Using Sophisticated Sequential Linear Approximation Method -Development and Application of User Oriented Design Optimization Language-

고성능 순차적 선형화 방법을 이용한 선박 최적 초기설계 기법 -최적화 설계 전용 언어의 개발 및 응용-

This paper presents a sophisticated Sequential Linear Approximation Method(SLAM) to solve nonlinear optimization problem and the performance of this method is compared with those of the Penalty Function Method(SUMT), Tangent Search Method(TSM) and Flexible Tolerance Method(FTM). To improve the convenience and flexibility in using the proposed SLAM, an user oriented design optimization language is developed and the application examples are shown for the optimization of propeller principal dimensions and the optimization of bulk carrier principal particulars.
