Diagram-led formal modelling using iUMLB for Hybrid ERTMS Level 3

Diagram-led formal modelling using iUMLB for Hybrid ERTMS Level 3
We demonstrate diagrammatic EventB formal modelling of a hybrid, 'fixed virtual block' approach to train movement control for the emerging ERTMS level 3.

We perform a full refinement-based formal development and verification of the key no-collision safety requirement.

The development reveals limitations in the specification, and identifies assumptions on the environment.

We reflect on our team-based approach to finding useful modelling abstractions and demonstrate a systematic modelling method using the UML-like state and class diagrams of iUMLB for EventB.

We suggest enhancements to the existing iUML-B method that would have benefitted this development.

The component and control flow architectures of the application and its environment and interacting systems emerge through the layered refinement process.

Abstract

We demonstrate diagrammatic EventB formal modelling of a hybrid, 'fixed virtual block' approach to train movement control for the emerging ERTMS level 3.

We perform a full refinement-based formal development and verification of the key no-collision safety requirement.

The development reveals limitations in the specification, and identifies assumptions on the environment.

We reflect on our team-based approach to finding useful modelling abstractions and demonstrate a systematic modelling method using the UML-like state and class diagrams of iUMLB for EventB.

We suggest enhancements to the existing iUML-B method that would have benefitted this development.

The component and control flow architectures of the application and its environment and interacting systems emerge through the layered refinement process.
