黄河流域骨干工程决策支持系统的系统分析与建模方法

阐述了在黄河流域骨干工程决策支持系统开发研究中所使用的建模方法．首先，在系统分析中，建立起系统的与或图，获得了系统中各决策问题求解序列、本原问题集合以及本原问题求解算法的集合．然后将其与广义模型化结合起来，采用零部件模型设计技术建模，这样使得系统资源（数据、模型、知识、……）达到了既是相互独立的，又可灵活地生成组合，协调运行，完成了系统所提供的决策支持功能．

System Analysis and Modelling Method of Decision Support Systems for Key Dams in the Yellow River Valley

The modeling method for Key Dams in the Yellow River Valley Decision Support Systems(KDYR DSS) is dealt with in this paper. First, the AND/OR graph is drawn by using the method of Problem Reduction, and the scheduling sequences of problem solving for KDYR DSS, the set of original problems and the solution algorithm set for original problem are abtained. Then in combination with the Generalized Modelling,the generalized program blocks are built with the technology of structrue programing, according to the scheduling sequences mentioned above. Therefore, the program blocks are not only independent, but can also be combined with each other flexibly.By running the program blocks coordinately, it provides decision supports to entire distribution of key dams.
