The synthetical optimization mathematic model on ship dynamic performance and structure characteristic is established in this paper. Composing parallel, GA and chaos algorithm, the parallel GA-Chaos algorithm is constructed, and it is applied to solve this kind of synthetical optimization calculation problem. The software with friendly interface is programmed by vc^＋＋. As far as the synthetical optimization problem of ship dynamic performance and structure characteristic is concerned, a large amount of optimization calculations of GA, chaos algorithm and the parallel or composite algorithm are carried out, which objective function is single or multi. The calculation results show that this algorithm not only can conquer the prematurity problem of GA, but also can save calculation time and have higher efficiency. The synthetical performance index of calculation results of ship dynamic performance and structure characteristic is higher than the index of congener optimization calculation. And it can provide the basic condition for the synthetical evaluation of ship design project and the ship form design.
