针对水资源调度管理决策特点 ,采用分布式面向对象技术 ,组建构件式的开发应用模式 ,把构件拓扑模型扩展到网络环境 .对构件经事件驱动方式 ,在可视的图形交互界面上进行决策导向 ,从而仿真模拟出用户需求 ,解决问题的方法既可视又可信 .新的模式体系开放性好 ,适宜决策服务的动态发展 ,经逐步发展扩充 ,可成为应用构件开发平台 ,有利于通用和实用 In view of the decision-making characteristics of water resources dispatching and management, a distributed object-oriented technology was used to set up a component-based development and application model, which extended the component topology model to the network environment.On the event-driven approach of component-oriented decision-making on a visual graphical interface So that the method of simulating and simulating user needs and solving problems is both visual and credible.The new model system is open and suitable for the dynamic development of decision services and has been developed and expanded gradually to become an application component development platform that is beneficial to both general and practical
