Abstract: Based on in-depth study of definition and characters of product platform, a structure-based product platform design method is proposed, which combines complex net theory and information axiom. It determines the importance of each node by calculating the total and average betweennesses of nodes in parts network of product family, and gets the key platform nodes with results of function analysis. Then it gets other important nodes by calculating the correlative coefficient between them and the key nodes. Using the information axiom evaluates the alternative platforms at last, and realizes the design loop. Complex net theory and axiomatic design method make this approach more clear and scientific. Taking the approach of wheel loader platform design as an example shows its systematicness and operability.
