ABZ 2020: International Conference on Rigorous State Based Methods

First Call for Papers, Answers to case studies, Workshops, Tutorials

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.

The name ABZ goes back to the first conference in London in 2008, where the ASM, B and Z conference series were merged into a joint event. In the following years other formal methods were added, e.g. Alloy in 2010 (Orford, Canada), VDM in 2012 (Pisa, Italy), and TLA + in 2014 (Toulouse, France). After the also successful 2016 conferences in Linz, Austria and 2018 in Southampton, UK, it was decided to name the conference "ABZ: International Conference on Rigorous State Based Methods", to stress the openness for further state-based formal methods. We hope to continue many fruitful discussions between representatives of the individual methods in the past, which will bring us closer to the common goal of this research community: the creation of reliable and safe software.

ABZ 2020 will have a main conference track, a case study track, tutorials and workshops.

Invited Speakers
Prof. Uwe Glässer, SFU, Burnaby, Canada
Prof. Yamine Ait Ameur, INPT-ENSEEIHT/IRIT, Toulouse, France

Case Study Track
As successfully practiced since ABZ 2014, the 7th edition of ABZ will again include special sessions dedicated to an industrial case study. Due to the proximity of Ulm to Stuttgart, where the headquarters of some automotive manufacturers and suppliers are located, it is obvious to provide a case study from the automotive industry.

We explicitly invite you to also submit contributions to case studies from previous conferences, which substantially extend the solutions presented there in one aspect or another. Possible enhancements could be new proof techniques, more elegant modeling, generation, verification, or validation of executable code, etc.
See web page for a detailed description of the new case study and links to the previous ones.

Main ABZ Track
Contributions are solicited on all aspects of the theory and applications of ASMs, Alloy, B, TLA, VDM, Z and other state-based rigour approaches in software/hardware engineering, including the development of tools and industrial applications. The program spans from theoretical and methodological foundations to practical applications, emphasizing system engineering methods and tools that are distinguished by mathematical rigor and have proved to be industrially viable. The main goal of the conference is to contribute to the integration of accurate state- and machine-based system development methods, clarifying their commonalities and differences to better understand how to combine different approaches for accomplishing the various tasks in modeling, experimental validation, mathematical verification of reliable high-quality hardware/software systems. Although organized to host several formal methods in a single event, editorial control of the joint conference is vested in one integrated program committee.

Workshop and Tutorial Proposals
Workshops and tutorials will be associated with the main event ABZ. Proposals are solicited in areas related to the conference topics.

A workshop proposal should contain the title of the workshop, a short description of the scientific content, the names and brief CVs of the workshop organizers, the intended PC for the workshop, the duration of the workshop, and the expected number of participants.

A tutorial proposal should contain the title of the tutorial, a short description of the scientific content, the names and brief CVs of the tutorial presenters and the duration.

Please submit your proposals to

Call For Papers
Four kinds of contributions are invited:

• Full Research papers: full papers of not more than 15 pages in LNCS format, which have to be original, unpublished and not submitted elsewhere.
• Short presentations of work in progress, and tool demonstrations: This is an excellent opportunity for Ph.D. students to present and validate their work in progress. An extended abstract of not more than 4 pages is expected and will be reviewed.
• Application in industry papers: reporting on work or experiences on the application of state based formal methods in industry. An extended abstract of not more than 4 pages is expected and will be reviewed. It is also an interesting option for industrial practitioners who sometimes face too many constraints to prepare a full paper.
• Answers to case study papers: full papers of not more than 15 pages in LNCS format reporting on the experiments conducted with any of the state based techniques in the scope of ABZ 2020. We also expect a link to a webpage, where the produced models can be downloaded.

Accepted papers will appear in the Springer LNCS proceedings. The deadlines for the different kinds of contributions see below.

"On B and Event-B: Principles, Success and Challenges: Jean-Raymond Abrial, Marseille, France"

"After more than 20 years since the publication of my book on B, and almost 10 years since the publication of my book on Event-B, the aim of this talk is to present some key points about these technologies. The talk will cover the basic principles on which B and Event-B have been developed and look at differences and similarities between B and Event-B. It will also outline where B and Event-B are spread around the world. Finally, the talk will explore challenges with the industrial application of these technologies."

Call for papers: History of Formal Methods 2019 Workshop, 11th October 2019, Porto, Portugal (co-located with FM'19)

We invite submissions to the HFM2019 workshop. See the website ( for complete details and instructions on how to submit. Submission is via EasyChair  (
This is a workshop on the history of formal methods in computing. The aim is to bring together historians of computing, technology, and science with practitioners in the field of formal methods to reflect on the discipline's history. There will be a round of abstract submission prior to the workshop which will determine who is invited to give a presentation at the workshop. Afterwards, presenters may submit papers based on their presentations for inclusion in the workshop's proceedings. 
The theme of the workshop is the history of formal methods in computing. By 'formal methods' we mean mathematical or logical techniques for modelling, specifying, and reasoning about aspects of computing. This could include programming language description, concurrency modelling, theorem proving, program specification and verification, or mathematical foundations of computing. 
Theoretical aspects of computing have been present almost since the beginning of electronic computers, and in various ways these techniques have evolved and changed, including into what are now called "Formal Methods". Such aspects have been instrumental in developing fundamental understanding of computation and providing techniques for rigorous development of software, but have not always had the desired impact on practical and industrial computing. 
This makes the field ripe for historical research and we invite submissions to our workshop which take a historical view of the topic. This may include discussion of developments of various formal methods, evolving agendas within the field, consideration of the effect of social and cultural factors, and evaluation of the way in which formal methods have impacted computing more broadly. 
The workshop is intended to be of interest to current researchers in formal methods and to be accessible to people without any historical background. It should also be a venue for historians of science whose work covers formal aspects of computing as we believe understanding the the history of the field brings greater clarity to current technical research. We encourage early stage researchers to try their hand at historical reflection and gain an idea of the field's grounding; we invite historians to contribute to the history of formal methods; and we invite researchers who have worked in formal methods for whom an historical talk provides the opportunity to reflect on their field.
Submission information
Submissions prior to the workshop will take the form of abstracts no longer than 500 words. If references are required, these can be added as an optional PDF file (and do not count towards the word count). All abstracts will be reviewed by the program committee whose details can be found on the website; based on these reviews, a decision will be made on who to invite to present at the workshop.
Following to the workshop, proceedings will be published (details of publisher to be finalised later). Please indicate during your submission if you wish for a paper to be considered for inclusion in the proceedings—select "Yes" even if you are not totally certain. All papers submitted for the proceedings will be subject to peer review.
