Automatic knowledge association system and method based on product design

Abstract

The invention relates to an automatic knowledge association system and method based on product design. The ontology technology, a machine learning algorithm and a solr index are utilized to realize fast retrieval and association of the design knowledge based on complex product design nodes, in the process of complex product design, the associated knowledge is self-organized through association rules based on case learning in the Bayesian networks, a user is provided with a reference design solution scheme, the design demand index situation is satisfied by the user according to the intelligentdesign knowledge pushed by a system, and applicability of the intelligent design knowledge is determined; if the intelligent design knowledge is adopted, the intelligent design knowledge is displayedas the design result at a client and is stored in a knowledge database; if the intelligent design knowledge is not adopted, the associated knowledge is referred by the client for manual design till the design result satisfies the design demand index, and the design result is uploaded to the knowledge database and stored as a product design case. The system is advantaged in that effective design knowledge reuse is realized, design efficiency is improved, the product design period is shortened, and manpower cost is reduced.

Description

Technical field [0001] The invention relates to a knowledge automatic association system and method based on product design, belonging to the technical field of knowledge engineering and knowledge automation. Background technique [0002] In the scientific research and production process of contemporary enterprises, through the division of labor and automation technology, physical work has been automated-completed by machines, while knowledge work still relies on people. Knowledge automation is to solve the problem of automating knowledge-based work, which is the future development trend of knowledge-based work. Automatic knowledge association is a prerequisite for achieving knowledge automation. [0003] The research work of knowledge association at home and abroad mainly focuses on how to mine effective information from data through association rules, which is used in library management, intelligence collection, and network information analysis. The knowledge association in the ...

Problems solved by technology

[0004] Currently, in the process of complex system design, designers in each position mainly rely on personal experience and knowledge to carry out design work. In the design of products or systems, it often takes a lot of time to search for information, resulting in slow product design progress and long cycles.

Historical product design cases and data are scattered in different people's computers, resulting in cases that cannot be shared and reused well, causing different people to perform repetitive labor for the same type of design work, low work efficiency, and waste of human resources
