Practice-Oriented Formal Methods To Support The Software Development Of Industrial Control Systems

Dániel Darvas, István Majzik, Enrique Blanco Viñuela
2017 Zenodo  
Model checking, one of the main formal verification techniques, is computationally difficult, therefore the analysis of non-trivial systems requires special considerations.  ...  Furthermore, the mainly academic tools implementing different model checking algorithms are not suitable for users who are not experts in formal methods.  ...  Although the use of model checking for PLC-based industrial control software was already studied in e.g.  ...

Behavioral types for component-based software systems

Jan Olaf Blech
2017 Proceedings of the Australasian Computer Science Week Multiconference on - ACSW '17  
In this paper, we particularly introduce the formal definition of behavioral types that are associated with system components in order to specify their expected behavior.  ...  Behavioral types for space-aware systems are proposed as a means to facilitate the development, commissioning, maintenance, and refactoring of systems with cyber-physical characteristics.  ...  The ESMs do not only facilitate the integration of the building blocks into their environment but make also compositional model checking of the building blocks possible.  ...
