Model and data integration and re-use in environmental decision support systems

摘要

A software architecture for the management of environmental models is presented. The Systems Theory representation of models is embedded in an object-oriented approach that emphasises the separation of models from data, thereby promoting model and data integration and re-use. The concepts presented here correspond to the requirements of a Model Management System (MMS). It is finally shown how a Decision Support System can use this approach to implement the MMS in order to facilitate problem definition (via the domain base) and problem solution (via the model base).
