This paper proposes an assessment method of complex product design associated with smart energy efficient manufacturing characteristics based on the universal logic. Semantic expression of complex product solution is accomplished by the function tree of AND/OR and matches proposition set. Evaluation index of product solutions is divided into functional index and smart energy efficient manufacturing index in unit of each individual match proposition. Then, assessment is implemented by a fuzzy synthesis algorithm. Universal logic of proposition autocorrelation and cross-correlation combined influence model of assessment for complex product design effectively deals with smart energy efficient manufacturing characteristics, and considers integration characteristics among each individual solution. The logic inference of compositional proposition realizes the overall scheme evaluation. Finally, a case study involving design scheme evaluation of high-precision gear cutting machine tool is described to illustrate the proposed method and the method is proven to be effective.
