Companies that operate and manufacture products in the technical area are exposed to increasingly challenging market situations. The developed products should be individualized to the customers' needs while offering high quality at an acceptable price.The temporal and especially economic claims are constantly growing, forcing the companies to develop a given product that matches the cost-side as well as the technical requirements in a short period of time. Following an initial development, it is often necessary to provide further product variants regarding a modified geometry or performance. A time and cost efficient way is the scaling of the initially developed product.Existing scaling methods focus on uniform geometry changes, not taking into account influences from non-uniform requirement or geometry alterations. Therefore, this article proposes an approach on how to modell and assess the outcome of a scaled assembly, based on the connection of individual scalable components inside an object-based approach.

“…Dimensionless products are to be derived from a dimension matrix. Two phenomena are similar when the dimensionless products of a complete set have the same value (Stichlmair, 1990). If all certain dimensionless potency products are constant over the entire area of application, the problem under consideration can be completely transferred from a model to a real size.…”

Similitude theory helps engineers to investigate system properties and behaviour with scaling methods. The application of such methods reduces the time for product development and production of prototypes. With increasing component size, the impact of size effects and nonlinear phenomena becomes more important in reduced scale model testing. The aim of this paper is to provide an overview of the scaling methods and their applicability with regard to size effects and nonlinear phenomena as well as a procedure to support the selection of a suitable method for the scaling task of structures.

“…For an effective way of system modeling the separation of domain and process knowledge plays a vital role. Therefore, the approach in this article is to model the components of a given product as separate objects, inheriting their specific domain knowledge, while combining these objects to form the overall system (Wolniak et al, 2018(Wolniak et al, , 2019. Figure 5 gives an overview of the overall functional analysis model structure.…”

When using product-service systems as a business model, new product development challenges and opportunities arise. Due to the possibility of customizing the product fleet depending on the user-scenarios, more product variants are possible and often necessary. Therefore, this paper presents an approach for the automated functionality and design optimization for user scenario specific use cases. The approach combines an optimization framework with a functional simulation model and a generative design approach CAD model. This results in a robust and simultaneously flexible design environment.
