Supporting the Synthesis of Validation Environments for Cross-System Generation Validation by Using MBSE Methodologies

The increasing complexity of cyber-physical systems (CPS) and shorter development cycles are leading to growing challenges in the synthesis of consistent and credible validation environments. This article presents a methodical, modelbased approach for instantiating such validation environments in the form of concrete validation configurations and validates this approach using the example of an existing, non-model-based validation environment for an electromechanical brake system. As an example, one of the component connections in the validation configuration is considered in the form of a shaft-hub connection. This connection should be selected and designed so that it is suitable for several generations of passenger car brake systems as well as for several development generations within a product generation. This example shows the procedure for creating the system of objectives with the validation objectives and requirements that result for the validation configurations and the resulting validation environment. The operation system is then used to create the system of objects for the validation environment, which involves mutual expansion and comparison with the system of objectives for the validation environment and comparison with the system of objectives for the product. The goal is to use this approach to come up with a model-based method for creating consistent validation environments. Initial implementations of the approach in a model-based systems engineering tool have already been done.
