Many industries have to react progressively to the increasing customer requirements regarding the individualization of products. As a consequence, companies are using more and more standardization methods, such as modular, platform or type series design. This leads to an increased complexity of product development processes and thus to the necessity of concepts which allow a consistent representation of constructions kits. Model Based Systems Engineering (MBSE) can support the development of such systems. A case study carried out in cooperation with thyssenkrupp Industrial Solutions shows the potential of the approach using the industrial sector, the machinery and plant engineering industry as an example.
