Focused on the limitations of formal representation and the reasoning method on case-based reasoning (CBR) reusable technology, the production case library is established by the extension reuse method based on CBR, the scheme cases in similarity design are obtained by retrieval algorithm based on the extension interval distance and the qualitative and quantitative reasoning method.The data mining based on the extensible congregation method techniques were researched, a kind of improved FP-growth algorithm of association rules was introduced to conduct the knowledge rule mining for product scheme design by applying extension transformation method, the adaptation of scheme design process for products was supported. The correlation analysis model for scheme design based on multi-attribute interval gray number is established for the implementation of the optimized programs. An example of hydraulic excavator structural scheme design was given, the structural scheme design and evaluation system are developed by VC++ and SQL, the effectiveness and feasibility of the extension reuse method is validated by the results.
