Towards Consistency Preservation for Multi-Domain Variability Modeling
Dirk Neumann, Tobias Pett, Ina Schaefer · 2025
Modern software-intensive systems comprise multiple engineering domains such as mechanics, electronics, and software.Traditionally, variability modeling approaches address variability by focusing primarily on a single domain.As a consequence, the management of multi-domain variability becomes a difficult task.One frequent outcome here is inconsistency, which means that the variability models of the different domains are incorrect.To address this problem, we propose a novel approach that combines consistency preservation for multi-domain models and delta-oriented variability modeling.By applying changes in form of deltas in one domain, our approach systematically derives corresponding deltas in other domains.In this way, we are able to ensure a consistent variant derivation process across domains.Our approach paves the way for further research on multi-domain variability management.
