项目摘要

In this research, we try to produce new knowledge bases systems on a work station for students majoring electrical areas to study about semiconductor devices, electronic circuits and circuit designings which have made remarkable technological advancement.As a ITS for electronic circuits made up LISP. We produced the user interface making possible to recognize simple answers in Japanese words, the circuit diagram drawing to indicate intentions of students and to recognize its circuit structure, and the numerical processing for expressing physical be haviors of circuits. And we tried to develop the student model and the tutoring module for ITS. We can realize the individual tutoring method according to student ability and progress.In a expert system that separates the knowledge bases and the reasoning mechanism for electronic circuits designing made up by symbol manipulation of C language, we extended to have the numerical analyzer and processor of simultaneous equations and so on. Consequently, we could easily get new and complicated informations and heuristic knowledge about the circuit designing in the knowledge bases.As the new methods of the designing of analog electronic circuits, we proposed the designing utilizing fuzzy theory. We tried to use the fuzzy sets which correspond to the design specifications and we could understand the mutual dependences among them. We could estimate the optimum amount of each element and device model parameters by utilizing the fuzzy decision. We could standardize the precise procedures of designing and had the optimum determination of element valuesin electronic circuits.

本研究尝试在工作站上为电气类专业的学生建立新的知识库系统，用于学习半导体器件、电子电路和电路设计等具有重大技术进步的知识。我们制作的用户界面，使可能认识到简单的答案，在日本的话，电路图绘制，以表明学生的意图，并认识其电路结构，和数字处理表示电路的物理参数。在此基础上，我们尝试开发了智能教学系统的学生模型和教学模块。在一个由C语言符号操作构成的电子线路设计专家系统中，将知识库与推理机制分离，扩充了数值分析器和联立方程组处理器等，从而使电子线路设计专家系统的知识库与推理机制相分离，使电子线路设计专家系统的知识库与推理机制相分离。在知识库中可以方便地获取有关电路设计的新的、复杂的信息和启发式知识，作为模拟电子电路设计的新方法，提出了利用模糊理论进行设计的方法。我们尝试使用与设计规范相对应的模糊集，我们可以理解它们之间的相互依赖关系。利用模糊决策，可以估计出各元件的最佳数量和器件模型参数。使设计的精确步骤标准化，使电子线路中元件值的确定达到最佳。
