knowledge base design 예문

• Knowledge base design of intelligent cad system
• As an important component of the above researches , this paper covers following aspects : ? firstly , product design theories are summarized , status and development trend of machinery product design are analyzed , and application of knowledge based design method in machinery product design is put forward . ? kbe ( knowledge based engineering ) theories such as knowledge acquisition , representation and storage are discussed , kbe concept is integrated with ug secondary development technology , and design knowledge is induced and stored to establish the design knowledge base . ? product case representation is researched , a hierarchical tree type product case library for complex products is established , retrieve strategy for cases of the nearest filed is put forward and corresponding algorithm is given
• Thirdly , the so - called fit degree and fit degree matrix are discussed to describe the rationale of knowledge supply and demand matching . furthermore , the entire design and implementation process of knowledge supply and demand matching based on an instance is discussed , including instance project introduction , knowledge base design and implementation , document management system and document fit degree management system implementation , middle layer operation process and user interface design . lastly , it summarizes the jobs the paper has done , focuses the prospect of knowledge search that should be done in the future and gives the essential program text of the system implementation
• Knowledge based design model is the refined quintessence of the designer ’ s experience . in the process of new product development , the reasoning machine is used to calculate problem solutions and the knowledge in the knowledge base is recalled for guidance , therefore to achieve enhanced overall product design level , shortened product development cycle and reduced new product investment risk
