Using delta model for collaborative work of industrial large-scaled E/E architecture models

Abstract

Development of model-based Electric/Electronic (E/E) architecture in the automotive industry poses a high demand on the data management of models. The collaborative modeling work involves stakeholders dispersed across various locations and departments, while the models themselves are often extremely large-scaled. In this paper, we present our approach addressing the model data management issue for both asynchronous and synchronous modeling. Compared to asynchronous modeling, which is based on the lock/commit mechanism for cross-department collaboration, synchronous modeling is targeted to assist quick and efficient interaction among small groups of members. We use the delta model for versioning in the database as well as for the synchronous modeling functionality. Furthermore, other versatile uses of the delta model such as the cumulative delta model and the reverse delta model are also introduced. © 2011 Springer-Verlag.
