建立高速单体船航行性能与结构力学特征综合优化的数学模型,将遗传算法改进成一种适应多目标和多约束的算法,并将其应用于高速单体船航行性能与结构力学特征综合优化计算问题,利用界面友好的VC++软件编程。优化结果表明,改进的遗传算法计算可靠、效率高,并为设计综合性能优良的高速单体船船型准备了良好的基础条件。

A synthetic optimization model of navigational performances and structure characteristic for the high-speed ships is set up;improve the GA algorithm into an algorithm which can suit the problem with many goals and many restrictions. And this algorithm is applied to optimize numerical results of synthetic optimization of navigational performances for the high-speed monohull ships, the software with friendly interface is programmed by VC ＋＋. The calculation results show that：using this software can conveniently get the possibility distributing function of integrate optimum navigation performance of each design variables, and can show that the latter is reliable and effective which provides fine support to the design of high-speed ships form with excellent synthetic performances.
