A Hierarchical Description Framework of Decision Model for Multilevel Users

To make up for the insufficiency of the existing methods of decision model representation in supporting multilevel model users, a kind of hierarchical description framework of decision model is proposed. This framework is made up of basic layer, building block layer and conceptual layer that supporting three kinds of model users, which are the model constructors, the DSS constructors and the decision makers or the decision analyzers, respectively. In the end of the paper, an example is given to prove the scientificity and feasibility of the proposed description framework.
