A Study on Models and Knowledge-Base for Intelligent Computer-Integrated Manufacturing Systems

1)分析了CAD、CAPP、CAM、CAPM等主要零部件中常用的产品模型、机械设备模型、工厂模型和管理模型的基本规格。在此基础上，应用结构化分析方法建立了ICIM的基本参考模型。2)从信息建模的角度对日本、美国和欧洲开展的ICIM研究工作进行了综述和分析。还对开发ICIM系统所需的一组计算机工具进行了调查和评估。开发了ICIM表示工具，对ICIM的静态功能结构和行为进行了建模。3)针对ICIM的应用，研究了面向对象的数据库系统，提出了ICIM数据库的需求规范。4)为了实现快速制造，实验开发了三维模型构造器，并通过多个案例进行了评估。对于ICIM的未来工作，必须结合并行工程的思想进行研究，并建立ICIM的信息基础设施。

The results of this research are summarized as shown below.1) Basic specifications of product models, machine/facility models, factory models, and management models, which are commonly used in prime constitutes - CAD, CAPP, CAM, CAPM -, are analyzed. Based on the analysis, the basic reference model is developed by applying the structured analysis method.2) ICIM research works which are carried out in Japan, U. S. A., and Europe are surveyed and analyzed from the viewpoint of information modelling. A set of computer tools which are necessary to develop ICIM systems are also investigated and evaluated. An ICIM representing tool is developed so as to model both the static-functional structure and the behavior of ICIM.3) Object-oriented database systems (OODBS) are examined with respect to ICIM application, and the specification required for ICIM database is proposed.4) Three-dimensional model constructor is experimentally developed so as to realize rapid manufacturing and estimated by a number of case studies.For the future works of ICIM, we have to study on the combination with the idea of concurrent engineering and the establishment of information infrastructure for ICIM.
