    • The invention relates to a method for analyzing the behavior of complex systems, particularly internal combustion engines, by forming a model that represents different test variables in accordance with input variables. Said method comprises the following steps:—different test points corresponding to different constellations of test variables are selected, and measurements are taken to determine test variables on a real system;—a model is established which shows the dependence of the test variables on the input variables, and said model is calibrated based on the test values of the real system obtained at the test points;—the model is subdivided into at least two partial models;—at least one first partial model is established which shows a first subset of the test variables;—at least one 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;—at least one additional principal influential parameter is identified for said other partial model;—an optimal value of the additional principal influential parameter is determined at each test point.
