Core Concepts
Rijkswaterstaat explores formal modelling for tunnel control systems to enhance standardization and communication.
Abstract
The content discusses the formal modelling of Rijkswaterstaat Tunnel Control Systems using SysML and Dezyne. It highlights the challenges faced in manual translation to formal models and the investigation of automatic translation to mCRL2. The structure, constraints, and benefits of each modelling approach are detailed, along with the strengths and weaknesses of the methods. Verification results and conclusions on the effectiveness of each approach are provided.
Stats
Rijkswaterstaat recognized the importance of formal modelling for tunnel control systems.
SysML models were created for all system parts of the tunnel control systems.
Manual translation of SysML models to mCRL2 was time-consuming and error-prone.
Dezyne offers a syntax similar to programming languages for formal modelling.
Dezyne uses mCRL2 as its verification engine.
Quotes
"The communication scheme employed in the SysML models of tunnels is that all components simultaneously read their input and deliver their output."
