Embodiment Construction
[0021] Such as Figure 1~5 In the shown embodiment: structured knowledge and semi-structured knowledge mainly use the bottom-up knowledge expression strategy, and for the unstructured knowledge such as a large number of text invention files and empirical knowledge in product design, choose top-up The following knowledge expression strategy is proposed, and the knowledge is expressed by Semantic Web; according to the expression of product design knowledge concept, Protégé tool is used to model the product design knowledge ontology, and the relationship between concepts is defined to solve the problem. Semantic representation of impeller design knowledge; knowledge retrieval algorithm is:
[0022] 1) In the present invention, the specification of user design knowledge requirements is a design knowledge ontology concept p
[0023] 2) Set a threshold for the concept , use the design concept similarity algorithm to find its similarity sim≥ in the design knowledge space composed ...

Provided is a multidisciplinary product design knowledge representation and management system based on a body and a blog. Through the fact that multidisciplinary design knowledge in a complex product design process is described in a formalization mode and a materialization mode, a proper representation strategy is used for describing related structural and semi-structural design knowledge, a symbolization and formalization process of design knowledge is completed, the product design knowledge is searched and classified according to relevancy and similarity of body semanteme, foundation is laid for product design knowledge management, a blog technology is used as an accomplishing means, and management processes to collecting, extracting, sharing, applying and the like of the design knowledge are achieved.
Description
technical field [0001] The invention relates to a system for expressing and managing multidisciplinary design knowledge supporting complex product design by using ontology and Blog technology. Background technique [0002] Product design is a knowledge-intensive process. The current ability to acquire, organize, transfer and apply the knowledge required in the product design process is still at a low level. This situation largely restricts product innovation. In order to shorten the product development cycle, it is necessary to realize the rapid acquisition and reuse of knowledge, which requires us to provide practical and effective methods of expressing, acquiring and utilizing product design knowledge, and truly use design knowledge as a design resource. It supports the execution of the product design e-Service chain and is specifically associated with the relevant design node solving process. [0003] The design of complex products is an integrated collaborative optimiza...
