For most hardware components in the automotive area, there is the problem that exchanges can only be done if the components are technically identical. That means not only identical in the interfaces and dimensions but also in the internal properties. These properties are firmly integrated in the software of connected hardware components. In this paper, an approach towards generic interfaces is proposed to identify this information and provide it on the communication interface. Furthermore, the influence of the specific information is reduced by an deployment optimization. Additionally, the communication overhead as well as necessary changes from a given original deployment are considered. A realistic case study is used to demonstrate the practicability of the proposed approach. It shows that it is possible to modify an existing application towards a generic communication interface. This approach proposes a combination of optimization and generalization in one procedure with respect to two acceptance criteria for a future realization. Not only theoretical best solutions are archived, but also solutions with a high chance to be accepted due to organizational changes.
