English Abstract To integrate most relevant aspects of the global
problem of climate change RIVM has developed a computer simulation model:
IMAGE (Integrated Model for the Assessment of the Greenhouse Effect). A
sensitivity analysis has been performed on this model, by having tried to
find a relationship between input- and output vaiables. In order to find
such a relationship, a metamodel is specified. A metamodel is a model
itself of the simulation model, a regression model. This regression model
supposes a linear relation between in- and output. By applying linear
regression with the least squares method, the regression coefficients of the
metamodel can be determined. With help of experimental designs, experiments
have been carried out as effective and efficient as possible. In this way
several modules of IMAGE have been analysed: the module concerning dike
raising and the costs of dike raising, and the carbon cycle module. For
these modules adequate metamodels have been developed.
