项目摘要

To promote the productivity, it is necessary to develop a total information system for management of factory. The object of this research is to make clear the structure of the system. To construct the system, we must discuss many problems as to acquisition and application of the information obtained f'rom the factory. Some problems about the constuction of the information system are also discussed in this research. The obtained results are the followings ;1.Diagnostic techniques are very important for the manegement of the production equipment. Four books showing the current techniques are published through this research.2.A tool for supporting construction of expert systems is developed. This tool has such a important point that the abnormal part is estimated corresponding to the accuracy of the observed data and the structure of the equipment.3.A calculation method is shown for the products being carried on the belt conveyor by using image processing.4.An auto-tuning fuzzy controler is developed.5.A simulator is very useful in suppoting the operation of the plant. We can also apply the simulator to detect the abnormality of the plant. In this research, system identification techniques are discussed for the detection of the plant abnormarity. Especially an algorism identifing closed-loop system is obtained. It will be very useful for practical applications.6.The basic concept of the total information system is presented and an example of the system is also shown.

为了提高企业的生产效率，有必要开发一个全面的信息化管理系统。本研究的目的是为了明确系统的结构。为了构建该系统，必须讨论工厂信息的获取和应用等诸多问题。本文还对信息系统建设中的一些问题进行了探讨。结果表明：1.诊断技术对生产设备的管理具有重要意义。本研究共出版了四本有关专家系统建构的书籍。2.开发了一个专家系统建构的辅助工具。该工具的一个重要特点是，根据观测数据的准确性和设备的结构，对异常部分进行估计。3.利用图像处理技术，给出了带式输送机输送产品的计算方法。4.研制了一种自整定模糊控制器。5.仿真器对支持设备的运行是非常有用的。我们还可以应用仿真器来检测设备的异常。在本研究中，系统辨识技术的植物异常检测进行了讨论。特别给出了一种闭环系统辨识算法。提出了总体信息系统的基本概念，并给出了总体信息系统的实例。
