A method for analyzing the behavior of complex systems, particularly internal combustion engines, wherein a model is established which shows the dependence of test variables on input variables, calibrating the model based on test values of the real system obtained at the test points subdividing into at least two partial models a first principal influential parameter is identified for the first partial model, an optimal value of the first principal influential parameter is determined at each test point, the first principal influential parameter is interpolated for all plausible constellations of input variables to calibrate the first partial model, another partial model is established to show another subset of test variables in accordance with the input variables and the previously determined first subset of test variables, an additional principal influential parameter is identified for the other partial model, and an optimal value of the additional principal influential parameter is determined at each test point.
