520			_aModel management is an important component of a decision support system (DSS). During the past fifteen years, several approaches to the representation of model schema have been proposed in model management. However, none of the current approaches can support all main objectives of model management (redundancy reduction, elimination of inconsistencies, model sharing with multi-users, ease of model 'use and standard enforcement). A deductive object oriented framework with inheritance mechanism between model classes is proposed for model management. Conversion algorithms from major current representations to this new framework is presented. Then, a retrieval algorithm of model base management is developed. Finally, a set of manipulative operations for model base management systems is formulated. In addition, a model query language (MQL) has been designed and implemented to support the set of manipulative operations for model base management systems. The proposed framework has several advantages. Firstly, it could be employed as a common representation for model bases. Secondly, the proposed inheritance mechanism enables the reuse of existing models. Thus redundancy and inconsistency in a model base can be reduced. The inference mechanism is employed to integrate models in the model base. So the compactness of the model base can be improved. Thirdly, a model builder can employ the retrieval mechanism to improve modeling productivity. Finally, the proposed model query language can be used to maintain models in the model base.
