Case-based reasoning method for complex product variant design

Abstract

The present application relates to a case reasoning method for complex product variant design. The case reasoning method for complex product variant design described in the present application includes the following steps: case representation, including constructing a complex product design knowledge domain ontology based on information from a product case database and information from a design solution, forming semantic relationships between concepts, and making classes and attributes controllable; ontology mapping, including using ontology-based data access technology, editing mapping files, and obtaining a case reasoning case library with semantic information; design problem rewriting, including rewriting design problems described in natural language into a resource description framework triple representation; semantic query, including performing reasoning access to the case library through query statements to obtain a subset of cases that meet design requirements; and, comprehensive similarity calculation. The case reasoning method for complex product variant design described in the present application has the advantage of high efficiency.
