Call for Papers Models for Formal Analysis of Real Systems (MARS 2027) April 11, 2027 Copenhagen, Denmark Affiliated with ETAPS 2027 https://mars-workshop.org/mars2027/ The MARS workshops bring together researchers from different communities who are developing formal models of real systems in areas where complex models occur, such as distributed and decentralised systems, cyber-physical systems, hardware/software codesign, biology, finance, quantum and reversible computing, etc. The motivation and aim for MARS stem from the following two observations: * Large case studies are essential to show that specification formalisms and modelling techniques are applicable to real systems, whereas many research papers only consider toy examples or tiny case studies. * Developing an accurate model of a real system takes a large amount of time, often months or years. In most scientific papers, however, salient details of the model need to be skipped due to lack of space as well as to leave room for formal verification methodologies and results. The MARS workshops aim at remedying these issues, emphasising modelling over verification, so as to retain lessons learnt from formal modelling, which are not usually discussed elsewhere. Examples are: * Which formalism was chosen, and why? * Which abstractions have been made, and why? * How were important characteristics of the system modelled? * Were there any complications while modelling the system? * Which measures were taken to guarantee the accuracy of the model? * How can different modelling approaches be compared on this system? We thus invite papers that present formal models of real systems, which may lay the basis for future analysis and comparison. In addition to the workshop proceedings, the formal models presented at the workshop will be archived in the MARS Repository, a growing, diverse collection of realistic benchmarks. The existence of this repository is a unique feature that makes MARS contributions available to the wider community, so that others can reproduce experiments, perform further analyses, and try the same case studies using different formal methods. SUBMISSION GUIDELINES All submissions will be peer-reviewed by at least three referees based on their novelty, relevance, and technical merit. The MARS proceedings will be published in the open-access EPTCS series (Electronic Proceedings in Theoretical Computer Science). Submissions must be unpublished and not be under review elsewhere. It is accepted, however, to submit a paper about a case study already mentioned at another conference, workshop, or journal provided that: (1) the formal model is submitted to MARS 2027 and has not been published previously, and (2) the MARS submission adds significant, novel material concerning the formal modelling work. Submissions must be in English and uploaded in PDF format via EasyChair (https://easychair.org/conferences/?conf=mars2027). Contributions are limited to 15 pages EPTCS style (not counting references and the appendices). Appendices of arbitrary length, included in the proceedings, can be added to present all details of a formal model. We welcome submissions that come together with one or many formal models that can be processed by some tool (e.g., timed automata for Uppaal, definitions and proofs for Isabelle/HOL, etc.). Such models should be complete (i.e., self-contained) and made available under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. The models associated with accepted papers will be made available in the MARS Repository. A URL to the formal models should be provided along with the submission. IMPORTANT DATES (AoE) * Submission: Friday, January 22, 2027 * Notification: Friday, March 5, 2027 * Final version: Wednesday, March 24, 2027 * Workshop: Sunday, April 11, 2027 KEYNOTES Alessandro Cimatti (Fondazione Bruno Kessler, Italy) Jan Friso Groote (TU Eindhoven, Netherlands) PROGRAM COMMITTEE Marco Bernardo (University of Urbino, Italy, chair) Jane Hillston (University of Edinburgh, United Kingdom) Radu Mateescu (INRIA Center at Université Grenoble Alpes, France) David Parker (University of Oxford, United Kingdom) Tatjana Petrov (University of Trieste, Italy) Anna Philippou (University of Cyprus, Cyprus) Anne Remke (University of Münster, Germany) Christian Schilling (Aalborg University, Denmark) Marjan Sirjani (Mälardalen University, Sweden) Maurice ter Beek (CNR-ISTI, Italy) Matthias Volk (TU Eindhoven, Netherlands) VENUE AND TRAVEL INFORMATION MARS 2027 is part of the European Joint Conferences on Theory and Practice of Software (ETAPS 2027).
