STUDY ON SIMILARITY AND SIMILARITY REASONING

摘要

Based on extension models of a new science called Extenics, this paper presents formalized study on similarity and similarity reasoning. The concepts of δ-similarity and δ-similar extension elements are introduced firstly, and then the substitution principles of similarity for solving incompatible problems are set up, showing that similarity substitution is an effective way to solve incompatible problems in the practical world. In addition, the quantitative calculation of similarity is discussed. Finally, three basic rules for similarity reasoning are developed as well.
