设计知识库 meaning in English
design knowledge base
Examples
- The knowledge database and the inference engine has good generality and expansibility by rationally designing the organizing structure of knowledge base , the order which the knowledge sorts in the database and the diagnosis flow of inference engine
通过合理的设计知识库的组织结构、知识在数据库中的排放顺序和推理机的诊断流程,很好的实现了知识库和推理机的通用性和可扩展性。 - Through acquiring designer ' s knowledge it is integrated with 3d digitization modeling technique , so automatically modeling and recycling knowledge for the textile machine parts in common use such as gear , etc is realized
研究了kbe理论，通过获取设计人员的设计知识实现了与三维数字化建模技术的集成。完成了设计知识库的创建，实现了齿轮等纺机常用件的自动建模以及对知识的继承和重用。 - 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
本文的主要研究内容及成果如下: ?对产品设计理论和方法进行了总结和概括,分析了机械产品设计的现状和发展趋势,将基于知识的设计方法应用到机械产品的设计中; ?研究了知识获取、表达、存储等kbe理论,并将kbe思想应用到ug二次开发中,将设计知识归纳存储,建立了设计知识库; ?研究了产品实例表示,建立了复杂产品层次树状产品实例库,介绍了最近邻域实例检索策略并给出相应的算法; ?研究了基于知识重用的三维产品建模技术,研究了在设计过程中的设计资源的重用,计算过程的重用,计算数据的重用,推理过程的重用等等;介绍了基于设计重用的凸轮三维模型的实现方法。 - The main reasons are as follows : firstly , the knowledge in knowledge base is not able to meet the needs of the system , because on the one hand , it is impossible and unrealistic to make it all - inclusive , and on the other hand , the representation of knowledge also restricts the functions of the systems ; secondly , though many intelligent instructional systems have been developed , seldom knowledge bases were designed utilizing method of knowledge engineering , which certainly affected the management , retrieving and sharing of the knowledge , and thus the maintenance and expansion of the systems
主要原因有：一是，知识库中的知识不能满足系统的需要，因为要想使知识库的知识包罗万象，是不可能的，也是不现实的；同时，知识的表示也制约了系统的功能。二是，尽管开发了许多智能化教学系统，但很少用知识工程的方法设计知识库。这样势必影响知识的管理、获取和共享，从而影响系统的维护和扩充。 - The sms representation scheme allows a given specification to be decomposed into an ordered sequence of sub - sms , and attempts to match each sub - sms with one or more stored basic mechanical units . thus , the possible solutions are generated . the data structures , the decomposing and the synthesis algorithm are presented according to the established mathematical models and the data base system
同时，结合关系型数据库系统对运动方案设计知识库的组织管理(包括基本变换单元信息的存储、提取操作及数据流间的复杂关系建立) ，提出了方案设计的综合求解算法，实现了在计算机上进行方案设计的可计算自动求解。
