On the overall optimization of navigational performance and structure characteristic for one kind of the high-speed ships

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.
