The correct-by-construction state-based Event-B formal method lacks the ability to express
liveness properties using temporal logic. To address this challenge, two approaches can be …

Hybrid systems are complex systems where a software controller interacts with a physical
environment, usually named a plant, through sensors and actuators. The specification and …

This paper contains the development of hybrid systems with Event-B and the Rodin Platform.
It follows the seminal approach introduced at the turn of the century in Action Systems. Many …

Event-B is a correct-by-construction rigorous state-based method offering features for formal
modelling and proof automation. An inductive proof schema allows to prove system …

This paper introduces a uniform substitution calculus for differential refinement logic dRL.
The logic dRL extends the differential dynamic logic dL such that one can simultaneously …

The design of hybrid systems controllers requires one to handle both discrete and
continuous functionalities in a single development framework. In this paper, we propose the …

Event-B developments are mostly structured around the refinement relationship. This top-
down development architecture enables system details to be gradually introduced into the …

Ensuring the safety of autonomous vehicles (AVs) is the key requisite for their acceptance in
society. This complexity is the core challenge in formally proving their safety conditions with …

The Event-B method enables correct by construction modeling of systems. It relies on set
theory and first-order logic, to describe a series of refined system models expressed as a set …

Checking the conformance of a system design to a standard is a central activity in the system
engineering life cycle, a fortiori when the concerned system is deemed critical. Standard …
