基于结构模型的模型管理

MODEL MANAGEMENT BASED ON STRUCTURED MODELS

为了使模型管理系统能支持三类不同层次的模型用户，探讨了分别面向信息用户、模型建立者和ＤＳＳ工具建造者的结构模型、模型网络图和模型描述语言的管理方法，讨论了模型描述语句的校验方法和模型描述语句与模型网络图的转换方法，提出了结构模型执行前提判断算法和执行后模型状态设置算法，并给出了在基础教育规划决策支持系统的应用实例．

In order to support three kinds of model users,the paper discusses the managing methods of structured models for information users and network diagram of models for model builders and descriptive sentence of models for tool builders of DSS,and presents the methods of verifying descriptive sentence of models and converting descriptive sentence of models into network diagram of models.In the paper,the algorithms of justifying the condition of structured models running and resetting the status of models after running are discussed,and the applying examples in decision support system of primary education planning are given.
