Abstract: In view of the excessive subjectivity in most existing methods due to a priori assignment of common platform parameters by designers during the design process of scale-based platform, a planning method for product platform based on axiomatic design and Sensitivity Design Structure Matrix(SDSM)was developed. The mathematical model for design parameters satisfying common platform parameters was deduced according to axiomatic design. SDSM which could describe the dynamic sensitivity relationships among design parameters and that between design parameters and functional requirements was established on the basis of design structure matrix. Then, common platform parameters were identified with scalable platform parameters according to SDSM, followed on with the optimization of their optimum solutions with non-dominated sorting genetic algorithm. Finally, an example of automatic bookbinding machine platform design verified the effectiveness of the proposed method.
