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
Based on the analysis of flood control experience and flood control decision-making process in the middle and lower reaches of the Yangtze River, the advanced technology is fully considered. In view of the development of the flood control decision support system in the Yangtze River, a system with reasonable system structure, advanced software design, good practicability and good scalability , To meet the real-time requirements of the overall design features, to determine the system’s development principles. Accordingly, the logical structure of the system is drawn up. With the database and knowledge base as the information base, the system operation environment is established through the master control program to realize the function of information inquiry and flood control dispatching. Information query With flexible and diverse query methods, the image of the form of intuitive expression to achieve real-time rainy weather conditions, flood forecast results and other information quickly query; flood control scheduling focuses on the use of flood evolution and scheduling model of the plan for the simulation of water regime for the decision-making Provide information on flood development. In order to effectively manage the model base, a design scheme of decision-making plan management system is put forward. In order to adapt to the latest development trend of software technology, the window software system with high starting point and difficulty of development is selected as the system software environment, and the graphical user interface technology is realized, the interface is friendly and intuitive, and the operation is flexible and convenient
