1) According to the knowledge level for reservoir operation, we proposed the knowledge acquisition process to find abnormality of weather situation and acquire the new information or countermeasure. The data of typhoon path, rainfall, and runoff characteristics are classified and added into knowledge base after integration with fuzzy set concept.2) Hyetograph and hydrograph are predicted through fuzzy-neuro prediction combined with fuzzy inference theory and neural network. Hydrograph was predicted with two approaches ; one was application of predicted hyetograph and the other was direct application of only observed inflow. Moreover, the acquired knowledge level was represented through the information theory.3) The virtual reality concept was introduced into the operation instructions where the panel operation, gate control and controlled results at upper or downstream points were reproduced with three-dimensional graphical system. The trainee can understand the real operation results of storage reservoir in control office.4) All of programming was applied to be structured with Visual C++ on personal computer. This software will support to make the proposed program compact and effective. As we obtained the monitored data different from the real-time data, the real application was not taken in this research.

1)根据水库调度的知识层次，提出了知识获取过程，以发现气象形势的异常，获取新的信息或对策。将台风路径、降雨量、径流特性等数据进行分类，并结合模糊集概念加入知识库。2）将模糊推理理论与神经网络相结合，采用模糊神经预测方法对台风过程和雨量进行预测。预报过程线有两种方法：一种是应用预报的雨量线，另一种是直接应用仅观测到的入流。将虚拟现实的概念引入操作指令中，将面板操作、闸门控制、上下游点控制结果用三维图形系统再现。培训人员可以在调度室了解水库真实的运行结果。4）所有程序均采用Visual C++在PC机上进行结构化编程。该软件将支持使拟议的程序紧凑和有效。由于所获得的监测数据与实时数据不同，本研究没有考虑真实的应用。
