Abstract: According to the adaptive problems of the products in the complex environment,an adaptable design method was proposed.The product environmental profile gene model was constructed based on sequential process events,production environmental factors and natural environmental factors.The environmental profile difference gene model was calculated by 5 kinds of genetic evolution forms such as the loss,increase,recombination of the key chain gene and the loss,increase of the branch chain gene.The design master was selected by comparing with the design fluctuations.The new product structure was adaptively designed according to the expert system of hydraulic press products/parts environment-function-carrier knowledge,which made the new products more effectively adapt to the complex condition.The feasibility of proposed method was proved by the application of a hydraulic machine hydraulic system design process.

Key words: complex condition, adaptability, environmental factors, product design
