【摘要】 供水系统是城市基础设施的重要组成部分，在保障城市发展过程中发挥着重要作用，关系到社会经济稳定发展和人民生活安定。随着市场经济的发展，人们对供水可靠性、安全性、经济性和运行管理提出了更高的需求。供水企业需要通过供水科学调度系统，逐步提高供水管理水平和服务水平。供水科学调度系统的建设是“国家供水行业2010年技术进步规划及2020年远景目标”内容之一，已成为供水企业信息化建设发展的必然趋势。 供水管网科学调度是指在供水系统集中、全面和实时监控的基础上，运用现代化信息技术，采取智能化和优化控制理论和方法，安全可靠地将符合流量、压力和水质要求的水供应给用户，在最大限度提高供水系统安全可靠性的同时，降低供水运行成本，提高运行管理平，提高供水企业的经济效益与社会效益。供水管网科学调度系统主要包括数据采集与通信网络系统、数据库系统、调度决策支持系统和调度执行系统。 调度决策支持系统是供水科学调度系统的核心。它应具有供水系统模拟、用水量预测、调度优化决策、调度状态评估等功能。根据文献，综合论述了供水调度决策支持系统的基本理论，包括管网系统宏观和微观水力模型、水质模型及以供水经济性和水质安全性为多目标的优化决策模型。提出了单目标决策数学模型与多目标评估体系相结合的研究方案。本课题的目标为： (1) 设计调度决策支持系统结构和工作流程，在供水管网地理信息系统、供水管网数据采集与监控系统基础上建立管网微观水力模型、用水量预测模型、优化决策模型、多目标决策评估体系等。 (2) 开发调度决策支持系统的关键实用技术，以保障调度决策的理论和方法在实际生产运行中发挥指导作用。 (3) 将以上研究成果进行系统集成，开发供水调度决策系统应用软件。 按照上述课题目标，完成了如下研究内容： (1) 管网模型的动态模拟计算。通过建立管网微观水力模型，将隐蔽状态的管网运行数据用计算机手段进行直观化的现实仿真。管网建模首先是将实际管网简化和抽象为管段和节点两类元素，并赋予工程属性，以表达管网的拓扑关更多还原

【Abstract】 Water supply system is an important component of urban infrastructure and plays an important role in ensuring urban development. With the development of market economy, the reliability, security, and cost in water supply system become a focus of attention, and the demands to the operation and management of water supply systems are urgently put forward. To satisfy those demands, the water enterprises need to develop scientific operation system in water distribution network by use of information technology and optimal control method, for improving the management and service and promoting economic benefit and social benefit. The development ofscientific operation system is one of contents of the planning——the technicaldevelopment planning of urban water supply systems in 2010 and the remote objects in 2020. It is inexorable trend of informational development of water enterprises.The scientific operation of water distribution network is supplying water safely and reliably to users according to requirement of the flow, pressure and water quality with information technology. The intelligent and optimal control theory and method are based on central comprehensive real-time monitoring in water distribution networks. While the safety and reliability of water supply system are enhanced, the cost of operation is reduced, and the scientific and technical level of the operational management can be improved. The scientific operation system in water distribution network includes the data acquisition and communication, the database, the operational decision support and the execution systems.The operational decision support system (ODSS) is the core of the scientific operation. It consists of functions of simulation of water supply system, water demand forecasting, optimal decision of operation, assessment of the operational state, and so on. In this paper basic theories of the ODSS are discussed, which include macro hydraulic model, micro hydraulic model, water quality model, and multiple objective optimal decision model, taking the economy of water supply and the security of water quality into account. Considering the safety of water quality in water更多还原
