The Design of Experiments (DoE) process is increasingly relevant due to the large number of parameters that need to be adjusted for modern internal combustion engines. A very important part of the development chain is the modeling, where the goal is the selection of the model that best describes the process to be analyzed. This used to hinge on the availability of an experienced modeling specialist. The fact that every day introduces a different set of complex optimization tasks in engine calibration - whereby additional DoE expertise is required to solve these problems - deters the implementation of the DoE process in the usual calibration process. In this context, a new approach that calculates a target-oriented synthesis model based on conventionally created models was developed so that designers can easily choose a model without need for a modeling specialist. The procedure is based on the hypothesis that the physical dependencies are predicted accurately in those areas, in which the different models, created using different equations, yield similar predictions; whereas areas in which model predictions do not coincide seem to have a pronounced mapping error. A new tool that evaluates the geometrical relationship between models was developed to validate this hypothesis. The tool can be used to create a synthesis model to better map the process with respect to any other model to which a comparison is made. Almost no statistical knowledge is required to create a synthesis model in the tool. This makes the tool much easier to use on a day-to-day basis and therefore improving the calculation procedure.
