Evaluation of Integrated Environmental Models. A Case Study

This report addresses the problems concerning evaluation of Integrated Environmental Models. The RAINS model developed at the International Institute for Applied Systems Analysis, Laxenburg, Austria is presented and analyzed as one example on an Integrated Environmental Model.
A sensitivity analysis was applied to parts of the RAINS model. This analysis focused on the socalled cost part of the model where economic considerations on emission reductions are sought described.
The report ends suggesting a number of criteria to base the evaluation of Integrated Environmental Models' usability on. These criteria widen the traditional evaluation concept and considers concepts as robustness, accuracy, simplicity, adequacy, transparency, and effectiveness. The criteria are concretisized by applying them to the RAINS model.
The report represents the third part of the Ph.D. thesis on Environmental Planning and Uncertainty.
