A Study on Methodology and Modelling for Knowledge Acquisition in Manufacturing Domain

本研究针对制造业知识进行研究，取得以下成果：1.知识建构过程分析：从历史的角度分析制造业知识的种类; 2.形态分析：通过对制造业知识形态的分析，确定了知识获取、利用、传播的主体、场所、形式，3.知识外化：利用多媒体和超文本数据库，开发了一种制造知识提取工具; 4.知识形式化：提出了一种制造知识在计算机上操作的形式化方法; 5.知识利用：提出了一种提高计算机中制造知识利用率的方法。6.形式化对象表示：提出了一种基于时空属性形式化的制造对象形式化表示方法。7.知识表示方案：一种制造知识获取方案，表示和利用的机器可理解的知识库。8。原型知识处理：一个原型系统的基础上提出的表示方案。

This research project with respect to manufacturing knowledge produced several results as shown below.1.analysis of knowledge construction process : Analysis from the historical aspect was done to clarify what kinds of manufacturing knowledge has been used in the manufacturing domain2.morphological analysis : A nalyzing the morphology of manufacturing knowledge was done to identify subjects, places, forms of knowledge in acquisition, utilization, and transfer of knowledge.3.knowledge externalization : A computer tool was developed to extract manufacturing knowledge by using multimedia and hypertext database.4.knowledge formalization : Aformalization method wad proposed in order to operate manufacturing knowledge in computers.5.knowledge utilization : A method which promotes the utilization of manufacturing knowledge stored in computer was proposed.6.formal object representation : A formal representation method for objects in manufacturing which is based on the space-time-attribute formalization.7.knowledge representation scheme : A scheme for manufacturing knowledge acquisition, representation and utilization was developed for machine understandable knowledge base.8.prototyping of knowledge processing : A prototype system based on the proposed representation scheme.
