“…Here, the SysML language is extended by a concept for variant modeling through additional stereotypes such as variant points or variation (Weilkiens 2016). One application of the VAMOS method is the systematic development of a federated database infrastructure and management system by Melzer et al (Melzer et al 2022). Melzer et al used VAMOS to model three different database types so that project teams can develop their own database independently using the same infrastructure.…”

This paper presents an approach to link heterogeneous and domain‐specific models. The background of this research is the complete investigation and comparison of cabin system variants, where many different aspects have to be represented. These include functional requirements, safety regulations, and geometric properties (e.g. installation space). However, these cannot always be validated or represented with just one model, as different levels of detail are required. Therefore, different discipline models have to be created, which in turn increases the complexity as a whole. Furthermore, the system to be represented by the models, such as the aircraft cabin, is already complex in itself. The many dependencies among each other and subsystems make it difficult to integrate new variants or technologies (e.g. liquid hydrogen) into the existing system architecture. The approach presented here therefore shows how the data and models of the different disciplines can interact with each other in order to be able to investigate variants holistically. This is demonstrated using the design of hatrack variants for a commercial aircraft.

The development of an aggregated system consisting of autonomously developed components is usually implemented as a self-contained unit. If such an aggregation is understood as a system of systems (SoS) that communicates via interfaces with its autonomous subsystems and components, the interfaces and communication exchange should play a central role in the architectural design. In fact, complete and exact interface specifications simplify loose coupling of independent systems into an aggregation. Since an SoS consists of variant and non-variant subsystems, the main challenge in SoS development is the identification of all true variants and its deviating attributes within an SoS. If the system variants are identified at an early stage of the development process, redundant work in the interface design can be substantially reduced. This paper presents an efficient method to identify SoS variants with regard to life cycle management and it shows how to configure a variant-oriented SoS with a standardized communication interface. For the development, the forward-looking model-based systems engineering approach is recommended to create executable specification parts and to detect errors early on through simulations.
