Economic Optimization in Preliminary Ship Design

선박기본설계과정(船舶基本設計過程)에서의 경제성검토(經濟性檢討)와 최적화기법(最適化技法)의 응용(應用)

The preliminary ship design step is made into a non-linear programming(NLP) problem. And using SUMT-exterior method and Hook Jeeves pattern search, the optimum ship characteristics are determined for the case where the ship is built in Korea and is operated by Koreans. Three programs for bulk carrier, tanker, and container ship are constructed and several sensitivity tests are performed. The result has little difference from the results of the other papers, but for high interest rate of return, slightly larger and faster ship is superior, and for low labour costs, slightly smaller and slower ship is superior.
