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．
The modeling method used in the research and development of the decision support system for the backbone engineering of the Yellow River Basin is expounded. First of all, in the system analysis, we establish the system and or graph, and get the set of solution sequence, the original problem set and the original problem solving algorithm in the system. Then it is combined with generalized modeling to model with component model design technology, so that the system resources (data, model, knowledge, ...) are both independent and flexible to generate combinations, coordinate operations, Completed the system provides decision support functions.
