Abstract: Aiming at the problem of the innovation strategy selection for product family in its evolution process, the integrated FAHP and TOPSIS methodology is proposed for the innovation strategy of product family as a Multi-Criteria Decision-Making（MCDM） model. The assessment index system and the MCDM model of product family innovation strategy are established based on the innovation strategy types and characteristics of product family. In order to deal with subjective uncertainty and vagueness, the FAHP and TOPSIS method are integrated to evaluate qualitatively and quantitatively the innovation strategy alternative of product family. Finally, an example is used to validate the model, the results provide a new prospective method to solve such problems in product family innovation and evolution.
