Abstract
Aiming to coexisting certainty and uncertainty of product attributes in case retrieval for the product family configuration design,a case retrieval method based on Projection Pursuit（PP）is proposed.Firstly,the uncertainty of product attributes is characterized by interval numbers,then real values interpolated randomly within interval numbers are used to replace interval numbers.Therefore,the number of resource cases and target cases is enlarged.On the work mentioned above,Projection Pursuit is used to get the best projection values.By using the projection values,the case retrieval considering uncertainty of product attributes in configuration design for product family can be completed.Case study of chain saw verifies the proposed method is of usefulness and effectiveness.关键词
