VAIVA GmbH - Safe Mobility



Theresa Ley,

We are continuing intensively with our Q&As on technical innovations and approaches at VAIVA. For example, model-based systems engineering.

Q: What is Model-Based Systems Engineering?

A: MBSE means an approach to describe systems with digital models, in contrast to document-based work-products, to support the whole development cycle of the product, such as requirements, design, analysis, verification and validation.

Q: Why is it important (now)? Why do we see such a hype in Automotive around MBSE currently?

A: Systems, especially vehicles and corresponding services, are becoming increasingly complex. And this complexity is more difficult to manage with just documents containing text or pictures, which are often stored in several different tools. That complicates understanding, traceability and creates unwanted redundancy, which leads to single-source-of-truth problems.
MBSE tools intend to contain all necessary information, in probably different views, each for its dedicated use case, but without redundancy and with implicit traceability.

Q: RFLP, SysML, Model-Simulation etc. – Which technologies, tools are relevant and how do we at VAIVA prepare for the future?

A: SysML is a standard language for modelling systems within a tool. Adhering to such a standardized language enables faster understanding of such models by relevant parties, and the possible usage of further tools that are compatible to this language. For example to apply a simulation of such models.

Model-Simulation: By creating a simulation of the future system behavior we hope to support our customers in uncovering the most useful behavior much earlier in the development cycle without relying on costly complete implementation down the stack.

RFLP is a method for handling complexity by dividing requirements- and architecture-definition into several domains.

We at VAIVA will integrate RFLP into our company wide process to enable its application for our projects. As well as we train our employees to apply SysML together with state-of-the-art tools.
