Abstract: A scheme solving process model of complex product conceptual design based evolution idea was instructed, a new hybrid approach based on cooperative co-evolution and interactive genetic algorithm was proposed. According to the characteristics of function design of cell phone conceptual design, a hybrid coding approach based on Messy coding technique and two-row chromosome structure was proposed. A case study was carried out to demonstrate its utilization and efficiency to conceptual design of complex product involving of multi-objective and human-computer cooperation.

Key words: Conceptual design, Cooperative co-evolution, Interactive genetic algorithm, Multi objective optimization, Human-computer cooperation
