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
Notification: March 22, 2027
Final version: April 5, 2027

Workshop proposals: December 7, 2026 AOE
Notification: January 11, 2027
Tutorial proposals: February 8, 2027 AOE
Notification: March 22, 2027

--------------------
Research Track (Main 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.

--------------------
Case Study Track:
--------------------

The objective of this track is to enrich the set of case studies (
https://abz-conf.org/case-studies/) developed with Rigorous State
Based Methods with a practical and real-life case study. Its goal is
also cross-fertilisation, enabling practitioners of the individual
formal methods to better understand each other.

The case study of ABZ 2027 is related to the 1961 UN Convention 
for the Reduction of Statelessness.

--------------------
Doctoral Symposium:
--------------------

ABZ 2027 will include a doctoral symposium. PhD students are encouraged
to report on their ongoing work or research plans and receive a valuable
feedback from the ABZ community. Accepted papers will be included 
in the ABZ proceedings.

--------------------
Workshops and Tutorials
--------------------

Researchers and practitioners are invited to submit proposals for
workshops and tutorials held in conjunction with ABZ 2027. Proposals are
solicited in areas related to the conference topics.
