Integration of iUML-B and UPPAAL Timed Automata for Development of Real-Time Systems with Concurrent Processes
[chapter]
2020
Lecture Notes in Computer Science
Preserved Fulltext
By integrating iUML-B and UTA, we combine the best verifying and validating practices from the two methods achieving a formal development of systems. ...
UPPAAL Timed Automata (UTA), on the other hand, address timing aspects of systems, and enable model checking reachability and timing properties. ...
We then investigated how the integrated approach addresses the development of complex real-time trigger-response pattern-based systems with concurrent processes. ...

These limitations make it more difficult to model and verify real-time systems with Event-B because it is very time-consuming to prove time properties in the Event-B framework. ...
the Event-B framework and cannot be smoothly converted to automata-based models such as timed automata that facilitate the verification of time properties. ...
S3 How does it express the vertical refinement process of the Event-B model of the real-time system? S4 How does it express the concurrent real-time objects? ...

Our work was inspired by our modelling and verification of a cardiac pacemaker, which includes concurrent aspects and a set of interdependent and cyclic timing constraints. ...
We provide a template-based timing constraint modelling scheme that could potentially be applicable to a wide range of modelling scenarios. We give a notation and Event-B semantics for the interval. ...
Moreover, timing constraints add real complexity to real-time control systems. Formal methods are used for rigorous modelling and verification of safetycritical real-time systems. ...

The authors of paper [67] show a solution based on Circus. The solution specifies the concurrent and parallel aspects of the system and it focuses on timing properties. ...
The authors of paper [75] model the system using iUML-B notation and then they verify the behaviour using the deductive theorem proving and model checking. ...
We plan to monitor the evolution of the standards.
ASMs The ASM process has been compared with the requirements of the standards. ...
