Paper Abstract

The present object-oriented model representing way have not fully addressed the issues of model inheritance for general users, increase the difficulty of maintenance and model composition, and make the interrelation among models more complex. This paper aims to make improvement in model presenting way and put forward a new model-base system frame, which can implement model inheritance for general users and its data and method are thought separately of as descriptive model (DM) and operative model (OM). The definition of operative model and descriptive ones, model representing way, correlation and how to ensure their consistency and inter-dependency were discussed in detail. Based on the frame, our group developed STA-MMS which can be incorporated into other decision support system (DSS) to manage models and to help users to build new models by reusing existing model resources in the system without modifying code. The architecture of STA-MMS system and its essential functions are defined. Procedures for model generalization, representation and composition are developed according to object-oriented concepts and methods. Finally, we examine how STA-MMS and its associated procedures and techniques are implemented in a prototype StaGIS to facilitate the construction, retrieval and execution of analytical models in the statistic analyzing process.
