Conceptual design knowledge representation method and knowledge management system based on ontology

Abstract

The invention provides a conceptual design knowledge representation method based on the ontology. The conceptual design knowledge representation method based on the ontology comprises the step that the vocabulary in a functional language bank is structured based on a preset functional language bank function group structure and a functional language bank flowing group structure to integrate similar functions; an ontology module of the design knowledge representation is established, and the ontology module of design knowledge representation comprises core concept and basic concept and possesses the mutual relation between the core concept and the basic concept; a module of design knowledge representation is established, wherein the design knowledge representation is one knowledge assemble of semantics and expression; inquiring, maintaining and managing are conducted on the design knowledge according to the structured function, the ontology module of the design knowledge representation and the module of design knowledge representation. The conceptual design knowledge representation method based on the ontology provides knowledge sharing and reusing for other designers in an enterprise and supports enterprise product conceptual design scheme innovation. The invention also provides a knowledge management system based on the ontology.

Description

technical field [0001] The invention relates to the field of intelligent information technology of advanced manufacturing technology, in particular to an ontology-based conceptual design knowledge representation method and a knowledge management system. Background technique [0002] As the initial stage and important link of product design, conceptual design largely determines the success of product design. With the shortening of the product update cycle, enterprises put forward higher requirements for engineers to innovate in the stage of product concept design. The main factors restricting enterprise innovation are: the design of complex products spans multiple fields and disciplines, and the lack of effective reuse of enterprise tacit knowledge. It is difficult for personnel to jump out of the existing thinking mode. In order to make tacit knowledge explicit and enhance knowledge sharing and reuse, computer-aided conceptual design has been proposed as an important means ...

Problems solved by technology

With the shortening of the product update cycle, enterprises put forward higher requirements for engineers to innovate in the stage of product concept design. The main factors restricting enterprise innovation are: the design of complex products spans multiple fields and disciplines, and the lack of effective reuse of enterprise tacit knowledge. It is difficult for personnel to jump out of the existing thinking mode

In order to make tacit knowledge explicit and enhance knowledge sharing and reuse, computer-aided conceptual design has been proposed as an important means to break through traditional constraints and promote design innovation, but there is still a lack of effective design knowledge representation methods that support computer understanding
