面向多级用户支持的决策模型层次描述框架

Multilevel-user-support-oriented hierarchical description framework of decision model

为支持参与决策问题求解和决策支持系统构造过程的不同层次用户,提出了一种决策模型层次描述框架。该框架由基础模型层、构件模型层和概念模型层组成。基础模型层从模型数据、方法和知识3个方面描述了基本的决策模型,用于支持模型构造者;构件模型层封装了基础模型的细节部分,通过接口向外界提供模型的基本信息,增强了模型的重用性,用于支持决策支持系统构造者;概念模型层通过给出决策问题的形式化表示,建立了决策问题与模型构件的联系,用于支持决策者或决策分析人员。通过实例,验证了本文提出的描述框架的科学性与可行性。

To support multilevel users participating in the process of decision-making problem solving and construction of Decision Support System （DSS）, a hierarchical description framework of decision models was proposed. This framework was made up of basic model layer, component model layer and concept model layer. The basic layer described basic decision models in terms of model data, method and knowledge to support constructors of decision models. The component layer was applied to encapsulate the details of basic decision models and supplied the basic information of decision models through interfaces to enhance the reusability of decision models. The component layer could be used to support the constructors of DSS. The conceptual layer established the associations between decision-making problems and model components through providing the formalized representation of decision-making problem to support the decision makers and analyzers. Finally, an example was given to prove the feasibility of the proposed description framework.
