Modeling Governance and Management in Socio-Technical SoSs


Systems-of-systems (SoSs) is becoming an increasingly important subject, in particular in the wake of digitalisation which affects every aspect of society. However, current concepts used to describe SoSs fail to capture the many nuances of the problem, and hence prevent the identification of useful solution patterns. This is particularly apparent when it comes to the modeling of governance and management aspects in SoSs, where the socio-technical nature is essential and involves both technology, humans and organizations. This talk will focus on a novel conceptualization of SoS based on models of independent decision making in SoSs governance, and the relation to system capabilities, situation awareness, world models, and utility. The approach will be illustrated from recent examples of collaborative SoSs in domains such as transportation and construction.


Jakob Axelsson received a PhD in computer systems in 1997, from Linköping University, Sweden. He then spent about 15 years in the automotive industry within the Volvo Group and at Volvo Cars. Currently, he is a full professor in computer science at Mälardalen University, and is also a senior research leader in systems-of-systems at RISE Research Institutes of Sweden. His research interests cover all aspects of system-of-systems engineering as well as system architecture for cyber-physical systems. He is the author of over 100 research publications and has received best paper awards at international conferences on four occasions. He was the general chair of the 16th IEEE System of Systems Engineering Conference in 2021.

Call for Papers


The goal of the GAUSS (Governing Adaptive and Unplanned Systems of Systems) workshop is to bring together researchers and practitioners working on the design, the development, the validation, and the continuous maintenance of Systems of Systems (SoSs). The workshop promotes research works on distributed solutions built on top of independent (sub)systems that seamlessly cooperate, even through emergent behaviors. In addition, research and case studies are in scope if addressing dynamic modules integration, autonomous reaction to unplanned scenarios, or dynamic evolution of SoS operational and managerial assets (i.e., environmental adaptation). Both the contexts encourage contributions focusing on ensuring desired sets of quality attributes (e.g., reliability, security, resilience) that SoSs must satisfy.

This year the GAUSS workshop is also focusing on the special theme: Engineering and Exploiting Microservice Architectures for SoSs. In addition to contributions fulfilling the core aims of the workshop, submissions about methods and solutions on this special theme are also encouraged.

The GAUSS workshop will accept regular and short papers reporting on research work, surveys, mapping studies, or presentations of case studies.

In addition, also for the current edition, the organizing committee is planning to invite the best contributions for a special issue on a Journal related to the topics of the Workshop (to be decided).

Submission Site


The list of relevant topics include but is not limited to:

  • Modeling, design, and engineering of SoSs
  • Architectures, architectural styles, and middlewares for SoSs
  • Foundations and formal methods for SoSs
  • Methods for architecture synthesis, coordination and adaptation patterns
  • Online V&V techniques for functional and non-functional assessment and dependability
  • Online and Offline testing techniques for SoSs and Complex Systems
  • Context-awareness and context-aware adaptation techniques
  • Reconfiguration and optimization techniques
  • Self-* mechanisms
  • Techniques for extracting behavior models from streams of continuos observations
  • Applications of SoSs
  • Distributed Software Engineering: strategies, processes, testing and methods
  • SoSs experiences, case studies, benchmarking, evaluations, testing, and industrial perspectives
  • Models of functional and non functional requirements, context and governance policies to support integration of SoSs
  • Knowledge management and Decision-making process in SoSs
  • Ambient Intelligent Systems
  • MultiAgents solutions for SoSs

Regular Papers

Papers submitted for evaluation must be original, unpublished, and not submitted for publication elsewhere. Any submission of a contribution implies that, if accepted for presentation, at least one of its proponents must register (paying the requested fee) and attend the conference for giving the presentation.

GAUSS 2021 accepts two categories of papers:

  • - Long: up to 8 pages (with reference)
  • - Short: up to 4 pages (with reference)

Papers that exceed the number of pages for that submission category could be rejected without review

Formatting Rules

Authors should submit an electronic copy of the paper (written in English) in PDF using the submission site.

Submissions must adhere to IEEE Computer Society Format Guidelines as implemented by the following LaTeX/Word templates:


Accepted peer-reviewed papers will be included in a supplemental volume of the ISSRE conference proceedings, and published by the IEEE Computer Society on IEEE Xplore.
We plan to invite some selected papers to submit an extended version to a special issue on a Journal related to the topics of the Workshop (to be decided).

Special Track: Journal to Workshop (J2W)

The GAUSS Workshop will also host a dedicated session to promote the community meeting and research sharing, accepting already published papers on journals related to the topics of the workshop.

Authors who had articles published on eligible journals between January 1st, 2020 and August 3rd, 2021 can propose their work to the J2W Track.

The proposed papers must be in the scope of the workshop; furthermore, they must not have already been presented in similar Journal First tracks. Please note that this kind of paper may be extensions of previous publications, but not from the previous GAUSS workshop editions.

Journals are eligible for the J2W Track if they:

  • - are indexed on Scimago
  • - are in subjects areas and categories related to the workshop (e.g., Computer Science, Software, Artificial Intelligence)
  • - have an average evaluation of at least Q3 in the last 3 years

Please note that the papers in the J2W Track will not be evaluated again by reviewers: their quality is already assured by the journals where they are published.
The selection process will only refer to the relevance and the affinity of the papers with respect to the workshop topics and the availability of the foreseen presentation slots.

J2W Track Submissions Rules

Authors should submit an electronic record (written in English) in PDF using the submission site.
Each record submission for the J2W Track must include:

  • - the title of the original article
  • - the complete list of authors
  • - the original abstract
  • - a list of keywords
  • - the full reference to the article as accepted by the journal (plus a link to the online version, if any)
  • - if available, authors can include a public version of the paper too (e.g.,preprint, arxiv link, etc.) [not mandatory]


All the papers accepted to the J2W Track will have a presentation slot to promote their work during GAUSS 2021. Please note that these papers will not be included in the proceedings: only the Title, Authors and Abstract will appear on the websites, plus a mandatory reference to the already published paper.
Any accepted submission to the J2W Track implies that at least one of its proponents must register (paying the requested fee) and attend the conference for giving the presentation.
