Abstract: To meet market's diverse requirements, concept of flexible product platform was introduced. By combining the advantages of the modular-based and the scale-based product platform design, a product family design process was established. In this process, market grids were partitioned firstly, and market segments, product variants, part of future uncertainties were identified at the same time. Then the part of known uncertainties was used to guide the current design. And the unknown uncertainties related to customer needs were analyzed to find out the key design parameters. Through mapping between the parameters and the physical structure, the critical flexible elements were determined. And the flexible product platform was constructed by extracting the common and the flexible elements. The unique elements were added to the platform so as to derive members of the product family. Finally, a design example of Numerical Control (NC) vertical grinder was used to demonstrate the effectiveness of this method
