 ---------------------------------------- First Call for Papers ABZ 2027: 13th International Conference on Rigorous State Based Methods Braga, Portugal, June 14-18, 2027 https://abz-conf.org/site/2027/ ---------------------------------------- The ABZ conference is dedicated to the cross-fertilization of state-based and machine-based formal methods, like Abstract State Machines (ASM), Alloy, B, TLA, VDM and Z, that share a common conceptual foundation and are widely used in both academia and industry for the design and analysis of hardware and software systems. The conference aims for a vital exchange of knowledge and experience among the research communities around different formal methods. ABZ 2027 will have a main conference track, a case study track, a doctoral symposium, tutorials and workshops. ------------------- Important Dates ------------------- Abstract submission (all papers): February 8, 2027 AOE Paper submission: February 15, 2027 AOE Notificati...

The engineering of industrial systems, particularly in safety-critical domains such as railways, demands rigorous verification and validation processes to ensure system dependability. Formal methods have emerged as powerful tools to complement traditional software engineering practices. In the railway sector, which increasingly relies on complex, distributed, and cyber-physical control systems, formal methods have demonstrated particular value for many decades now. In this paper, we provide a retrospective overview of the application of formal methods and tools in the railway domain, with emphasis on two prominent verification approaches and one frequently verified railway system: modelin...

 Foreword of the book "SPECIFICATION CASE STUDIEs" edited by Ian Hayes Reading formal texts is like meeting people. Sometimes, you understand them straightaway like good friends who take to each other immediately. At other times, it is more difficult. You may parse what you read, but find it impossible to work out any meaning. With the latter, you have to be patient, ask questions, explore the surroundings; in other words, it is better for you to be introduced through some common good friends who volunteer to help you prepare for the first meeting. Large computer programs, to say the least, pertain to the category of formal texts whose meanings are not immediately obvious! For that reason, people have been trying – for some time – to find out what kind of intermediate text would be best suited to play the role of go-between. This book reports on experiments made at Oxford University within this frame- work: it shows how one may communicate ideas and meanings about existing (o...
