The system possesses the real time correcting function , which can avoid error accumulation and highly increase the forecasting accuracy ; ( 3 ) the flood control system can be multiple - scheme designed , that is , the control schemes can be designed in terms of different control ways for hydro - projects . simulated computation can be carried out to obtain multiple schemes that can be used by the leaders for decision making after risk and consequences estimation , so as to scientifically enhance th 系统具有实时校正功能,可以避免误差累积,极大地提高了预报精度; ( 3 )防洪调度系统可以进行多方案设计,即可以根据水工建筑物不同的调度方式来设计调度方案,并进行仿真调度计算,最终生成多个方案,供领导决策,提高了防洪决策的科学性; ( 4 )系统采用的数据均建立在实时雨情、水情、工情和天气预报等数据库基础上,预报、调度均能做到快速及时。
In this paper , the total design of decision support system for basin flood control scheduling is systematically described ; the decomposing principle for complicated flood control system is proposed , a models library satisfying the different requirement is established , and the quick creation of scheduling scheme and build of consultation and analysis system is thoroughly studied 论文系统描述了流域防洪调度决策支持的总体设计思想,提出了复杂防洪系统的分解原理,建立了适应不同要求的模型库,并就调度方案的快速生成和会商分析平台构建进行深入研究。
The class definitions and knowledge rules are delineated . at the same time , inference engine is given . by use of visual rule studio , a hybrid expert system shell , as an activex designer under microsoft visual basic 6 . 0 , a software system of watershed hydrology forecast models is developed successfully and integrated into reservoir flood control system 利用visualbasic面向对象的编程技术和其他计算机技术如大型数据库开发技术,结合商业软件visualrulestudio ,成功地开发了流域水文预报模型知识管理软件系统,并将其集成到现有的水库洪水调度系统中。
By choosing flood control system of downstream basin of the yellow river as the background , six relatively independent subsystem is established , which includes basic information management , real - time flood forecast , multi - reservoir flood control scheduling , consultation and analysis , scheduling scheme management , frequency analysis , and assist with friendly man - machine conversation to constitutes the yellow river downstream flood control scheduling decision support system , which can satisfy the practicability requirements of decision - making 论文以黄河下游防洪系统为背景,建立包括基本信息管理、短期洪水预报、水库(群)防洪调度、会商与灵敏度分析、方案管理、水雨情频率分析等6个相对独立的子系统,并辅以友好的人机交互界面集成为黄河下游防洪调度决策支持系统,满足了群决策会商的实用性要求。
