Multilevel-user-support-oriented hierarchical description framework of decision model
Yongtao Xu · Computer Integrated Manufacturing Systems · 2007
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.
