Abstract: In order to improve design efficiency of intelligent generation and optimization about
design scheme, and increase the designer′s understanding of physiological, psychological and
environmental constraints about DSV ergonomics design, the layout design about man machine
interface component is solved by genetic algorithm, knowledge reasoning is used to the color
ergonomic design about manned capsule, and the intelligent optimization about manned capsule
ergonomics design based on particle swarm optimization algorithm. The prototype system is
developed for manned capsule CAED based on UG. The feasibility of layout design solution about
man machine interface component and intelligent optimization about manned capsule ergonomics
design is verified by using a design example.

Key words: multi-constraints, deep submergence vehicle, human machine interface, ergonomic design, computer aided system
