Formal methods are now industry ready, able to scale up to real siez railway projects and to provide a real for successfully completing safety demonstrations. In this white paper, we show that several formal methods (B, Event-B, formal data validation) directly contribute to safety critical software development, system-level sprecification analysis and constant parameters validation, with […]
ClearSy will participate to the international conference SBMF 2017 (http://sbmf2017.cin.ufpe.br/) on formal methods that will take place on November 27-December 1 2017 in Recife (Brazil). At this occasion, ClearSy will present a scientific article entitled “Applying a Formal Method in Industry: a 25-Year Trajectory”. Moreover, a dedicated training session will be organized during ETMF 2017 […]
Proven software with B executing on Low Cost High integrity Platform”, is aimed at presenting the latest innovations concerning the use of the B formal method for the development of safety critical systems
David Deharbe – Universidade Federal do Rio Grande do Norte, Natal, Brazil Abstract: In this talk we describe a multi-platform code generator for the B method. In particular, we present a translation procedure from a larghe subset of the B language for implementations towards LLVM source code. This translation is defined formally as a set […]
ABZ 2014 conference was held from June 2d to 6th in Toulouse. It was attended by about 120 people and allowed B, Z, ASM, Alloy and VDM communities to meet and exchange ideas. The diversity and relevance of the work presented, as well as the presence of significant industrial, reflect a growing force in the […]
At the occasion of the ABZ 2014 conference, a tutorial on formal data validation is organized at ENSEEIHT together with workshops (see details here). The tutorial will happen on June 3rd 2014 from 2:00 pm to 5:30 pm. During this tutorial, formal data validation principles will be exposed (key concepts, mathematical language to express properties, […]
On March 14th, 2014, we shall present to M2 STL students – Pierre & Marie Curie University in Paris, various industrial cases of the use of the formal B method.
ClearSy is contributing to a technical seminar organized by Newcastle University on 24 October 2013. Formal methods are used worldwide to improve safety in several railways applications, at various levels and with a wide range of results obtained. This presentation is intended to provide a unified (not agnostic) overview of existing practices and to assess to which […]
ClearSy participated to CAI 2013 conference (International Conference on Algebraic Informatics) held in Porquerolles (France) 3-6 September 2013. A talk, entitled “Railways formal data validation“, was given during the industrial session.
ClearSy attended a Seminar,”Integration of Tools for Rigorous Software Construction and Analysis” (13372), held at Schloss Dagstuhl in Germany (8-13 September 2013). The program spans from theoretical and methodological foundations to practical applications, emphasizing system engineering methods and tools that are distinguished by their mathematical rigor and have proved to be industrially viable. A main goal of the […]
