MBSE Beyond SysML
In today’s competitive environment, product development is under pressure from all sides: shorter timelines, rising complexity, shifting customer expectations, and the accelerating demands of digital transformation. Model-Based Systems Engineering (MBSE) is emerging as a critical capability to meet these challenges head-on—uniting technical disciplines, enabling business agility, and creating a solid foundation for future-proof decision-making.
But then you need to see beyond SysML! See the results here
Come and join the conversation!
The day will be divided in two tracks, trying to take a holistic view of MBSE in relation to two topics. MBSE Forum will during the seminar/workshop focus on some predefined questions per topic and we will try to find an answer to them during the day.
Topic 1
- The Architecture of MBSE
- What does the overall model landscape look like?
- How do we make model purpose explicit?
Topic 2
- V&V, Simulation and MBSE
- What is required to trust a simulation in your context?
- What is the difference between a design/analysis model and the system architecture model?
- How can you reason about what simulation model is appropriate in a decision-making context?

Excuse me Sir/Madam – which model
Abstract: Development of complex systems through the application of Model-Based Systems Engineering (MBSE) will require the creation and maintenance of multiple models, created using multiple languages. Hence, structuring the models such that there is efficient support for incremental development requires some foresight. Having models with multiple or unclear purposes may introduce situations where parts of the organisation will ask for modification for representing a desired future system state, whereas other parts of the organisation require it to remain unchanged in order to represent the present state. This paper introduces a structure with associated terms and characteristics of the different model types in order to provide guidance to an organisation. In particular, it extends previous work on model tenses, capturing different time perspectives/purposes on the models, to also include model usage for keeping track of the actual state of a realised system instance. For example, the concepts of Digital Twin and Digital Shadow are discussed and conceptualised. As such, the contributions made in the paper allows an organisation to reason about the completeness of their modelling methodology and its applicability to support incremental development. Above all, the paper spells out clearly that for a complex heterogeneous system, any request for an update to “the model” will prompt the response “Excuse me Sir/Madam, which model?”.

Early Validation & Verification in Model-Based Systems Engineering
Abstract: This presentation will discuss the role of simulation for early V&V in the context of model-based systems engineering. I summarize some relevant findings from my PhD thesis work on this very topic, and provide a few examples of how simulation can be integrated into MBSE, and what challenges exist in this context in addition to enables. The existing research offers an academic look into these concepts and provides a starting point for industrial integration of simulation as a driver during early MBSE stages.
Johan Cederbladh is a global architect at Volvo Construction Equipment working with simulation and Model-Based Systems Engineering (MBSE). He has a master of science in dependable aeronautical systems engineering from Mälardalen University, and a PhD from Mälardalen university in computer science on the topic of early V&V in MBSE.
