Actually, the safety control is one of the most important aspects studied by the international researchers, in the field of design and development of automated production systems due to social (avoid work accidents, ...), economics (machine stop time reduction, increase of productivity,...) and technological aspects (less risks of damage of the components,...). Some researchers of the Engineeri...

We integrate a verified typechecker with a verified program logic for the C language, proved sound with respect to the operational semantics of the CompCert verified optimizing C compiler. The C language is known to not be type-safe but we show the value of a provably mostly sound type system: integrating the typechecker with the program logic makes the logic significantly more usable. The comp...

We demonstrate the use of a hyper-programming system to build persistent Java applications in PJama, an orthogonally persistent version of Javaa. This allows program representations to contain type-safe links to persistent objects embedded directly within the source code. The potential benefits include greater potential for static program checking, improved efficiency, and reduced programming e...

Context: Demonstrating compliance of critical systems with safety standards involves providing convincing evidence that the requirements of a standard are adequately met. For large systems, practitioners need to be able to effectively collect, structure, and assess substantial quantities of evidence. Objective: This paper aims to provide insights into how practitioners deal with safety evidence...

Operating-system verification gains increasing research interest. The complexity of such systems is, however, challenging and many endeavors are limited in some respect: Some projects focus on a particular aspect like memory safety, not pursuing functional correctness. Others restrict their verification efforts to a single layer of software, assuming correctness of those below. Only few project...

The problem of coordination is central to research in robotics, automatically guided vehicles, autonomous cars, unmanned aerial vehicles, and any other areas in which autonomous agents of any kind operate concurrently. This paper focuses on one particular model of coordination, namely Comhordú. The contribution of this work is a formalisation of the existing model in precise mathematical terms....

Using probabilities in the formal-methods-based development of safety-critical software has quickened interests in academia and industry. We address this area by our model-driven engineering method for reactive systems SPACE and its tool-set Reactive Blocks that provide an extension to support the modeling and verification of real-time behaviors. The approach facilitates the composition of syst...

Robots are solving challenging tasks that we want them to be able to perform (liveness), but we also do not want them to endanger their surroundings (safety). Formal methods provide ways of proving such correctness properties, but have the habit of only saying “yes” when the answer is “yes” (soundness). More often than not, formal methods say “no”: They find out that the system is neither safe ...

This paper presents an original approach developed within an industrial thesis, financed by the SNCF (French acronym for National Society of French Railways). The aim is to standardize the work of electric traction of railway transportation. This approach is composed of two axes. Firstly, a standardized generation of deliverables is done to help the systems engineers keeping their concentration...
