The design of the flight deck layout is a critical and difficult point in the general design of aircraft carriers, and the optimization of which significantly improves the deck arrangement, and sortie gener- ation capacity of aircrafts. To reduce the complexity and diversity of the flight deck design process, a para- metric modeling approach is proposed, and the relation between the flight deck layout and the various char- acteristic parameters is established. Also, multi-objective genetic algorithm is presented based on the mathematic and optimization model of the flight deck design. The result shows that parametric optimization approach is able to efficiently transform the complex design process to the optimization of a few parameters affecting the performance of the flight deck, and the optimal solution set can be then obtained through the multi-objective genetic algorithm.
