A NEW MODEL DESCRIPTION METHOD INDECISION SUPPORT SYSTEMS

Model management is an important research area in （G）DSS. A mathematical model is thought of as the integration of attribute data, operation, and knowledge. A new method of object\|oriented model description with embedded knowledge, called OOMDEK, is implemented. From the point of view of model integration, three kinds of multiple inheritance are proposed. The role of knowledge in model management and the implementation of model base are explored,and model management system is also covered.
