长江防洪决策支持系统总体设计

在分析总结长江中下游防洪经验和防洪决策流程的基础上,充分考虑技术的先进性,针对长江防洪决策支持系统的开发,提出了具有系统结构合理、软件设计先进、实用性强、扩充性好、适应实时要求特点的总体设计,确定了系统的开发原则.据此,拟定了系统的逻辑结构;以数据库、知识库作为信息基础,通过总控程序构筑系统运行环境,实现信息查询和防洪调度的功能.信息查询以灵活多样的查询方式、形象直观的表达形式来实现对实时水雨工情、洪水预报结果等信息的快速查询;防洪调度侧重运用洪水演进和调度模型对预案进行水情仿真,为决策者提供汛情发展事态信息.为对模型库进行有效的管理,提出建立决策方案管理系统的设计方案.为适应软件技术的最新发展趋势,选择了起点高、开发难度大的视窗软件系统作为系统的软件环境,实现了图形用户界面技术,使界面友好直观,操作灵活方便.

Framework and Design of the Yangtze River Flood Control Decision Support System

Based on the experience and existing decision-making procedures of flood control on the middle Yangtze River, a framework-design for developing the Yangtze River flood control decision support system (YRFCDSS) has been proposed, featuring by an appropriate system structure, advanced software design, excellent problem-solving abilities, good extensibility and compatibility to keep up with technical changes, and suitability for an efficient and flexible real-time management. The paper out lines an approach and some guidelines for developing YRFCDSS. The logic structure of the system was determined as follows: under supports of a data base and a knowledge base, the entire operational environment for the system was set up through the main control programs, realizing two main functions of in teractive information providing and flood control system simulation. To build YRFCDSS effectively, some key-techniques including GIS, graphical user interface, model managers, and other advanced human-computer in teraction were also addressed.
