    <abstract>The paper presents an approach to the analysis of the Simplified Ozone Model (or: Integrated Assessment Model for Ozone) that describes the relationship between ozone (O3) exposure and the emissions of ozone precursors, NOx (nitrogen dioxide and nitric oxide) and VOCs (volatile organic compounds). The model is currently being developed by the Transboundary Air Pollution project using data calculated by the EMEP Ozone Model which deals with ozone concentrations over long periods and covering the whole Europe. The model is to be used for analysis of different policies of emission reductions and their influence on O3 concentration experienced by the receptors. 

The final version of the model will be a large scale nonlinear programming model. Therefore software tools for the generation and analysis (by both optimization and simulation) of the model are needed. The paper presents the developed prototypes of the needed software tools. The tools include a model compiler which generates C++ code needed by any nonlinear solver for computing values of goal functions, constraints and the Jacobian (which is generated using a symbolic differentiation tool). More general problems related to generation and solution of large scale nonlinear programming problems are also discussed and recommendations for further research are summarized.</abstract>
