The Systems Thinking Competence Center of Zielpuls, under the direction of Florian Lux, combines Zielpuls’ experience of more than 20.000 project hours in the context of MBSE (Model Based Systems Engineering) within and also outside the automotive industry.
Difficulties with MBSE as a holistic concept
MBSE is one of the most considered approaches to develop complex products. Especially in the automotive domain there have been already quite a few projects aiming to roll-out holistic MBSE concepts for the entire vehicle development process. However, most of those projects have failed or have not finished yet because all of them struggle with the same major challenges this domain provides:
- Environment/Domain defined by system of systems and resulting multi-layered integration process
- Enormous variant complexity of functional and technical architectures
- High degree of reusability and technical debts
New MBSE metamodel ZiMA
From the perspective of the Zielpuls consultants these three challenges must play a major role while deriving the individual MBSE approaches. Together with Elisabeth Eichstetter from Hochschule München Zielpuls started to create such an automotive-specific MBSE meta-model consolidating experience of all related Zielpuls projects. The release of the Zielpuls Metamodel for Automotive (ZiMA) is planned for the end of the year 2020. But the Zielpuls team is already giving a small foretaste of the expected results:
Consequent abstraction layer approach to handle the huge product complexity. ZiMA uses five of these abstraction layers from “Portfolio” to “Component” allowing to communicate on the right abstraction layer while collaborating in the organziation.
Less is more to enhance collaboration and reuseability in large organizations. ZiMA concentrates on three types of SysML diagrams only. More is of cource possible depending on the subsystem’s type and complexity. However, on a organizational scale it is essential to concentrate on the product’s behavior, its structural elements and their interfaces.
Logical architecture as a stable ancor towards the enormous technical product variants. ZiMA proposes two types of structures diagrams – logical and technical ones. This allows to derive a stable and variant-independent logical architecture while having for example brand-, vehicle type- or country-dependent technical architectures.

The future should bring more innovation in less time
The focus of the remaining three months is to vaildate the approach with the most relevant use cases for vehicle development. First results are promissing showing that the framework can cover the wide range from minor change requests for an existing E/E architecture to the derivation of entirely new and cross-brand architectures. With the derived stable functional architecture and flexible system architecture this approach can guide through the dilema of current vehicle development: provding more and more innovations in a shorter period of time.
