Smarter Building Design
• Models of large-scale, open, diverse data integration
• … coupled with models of physics• Need to model learning behaviour • Possible integration of models of
human behaviour
• Need to model control and planning/re-planning
• Models of locality and mobility• Real-time behaviour modelling• Domain-specific reference models

INTO-CPS: A new 8 M€ H2020 Project
6
1. Build an open, well-founded tool chain for multidisciplinary model-based design of CPS that covers the full development life cycle of CPS
2. Provide a sound semantic basis for the tool chain
3. Provide practical methods in the form of guidelines and patterns that support the tool chain
4. Demonstrate in an industrial setting the effectiveness of the methods and tools in a variety of application domains.
5. Form an INTO-CPS Association to ensure that project results extend beyond the life of the project

• Modern systems are complex
• To cope with this, we can build models beforehand– To perform analysis (e.g. static analysis, proof, model
checking, simulation)– Clarify our assumptions– Evaluate potential designs– Avoid expensive prototypes
• Different modelling paradigms for different aspects
12
Model-driven Design
• SysML– Use Case diagrams– Requirements diagrams
• Informal (link and traceable)• Formal (LTL, Test automation)
