Abstract: To improve the efficiency of large-scale container crane product design,a 0-1 programming gene evolutionary model with constraints was constructed,in which the partial similarity between case templates and customer requirements,partial green characteristics satisfaction degree,compatibility among sub-parts and so on were synthetically considered,and a product configuration algorithm based on improved ant colony was built.According to the product configuration design characteristics of large-scale container crane,pseudo random proportional rule of ant colony algorithm was redesigned.Aiming at the large quantity of candidate gene-instances,a scheme to reduce the number of candidate gene-instances was proposed.An x_Sigmoid function was designed to adjust transition probability for picking up the algorithm search speed.A prey strategy was implemented for strengthening the better regional exploitation to expand the search capability.Through a case of cart mechanism design for container crane,the optimizations of different algorithms were compared and the effectiveness of proposed model was verified.
