Scope

Systems of Systems (SoSs) are gaining momentum due to the widespread adoption of Internet of Things (IoT) technologies, an increasing interest for smartcities, digital twins, and industrial cyber physical systems. The heterogeneity and large scale of these systems require novel design techniques, architectures and software infrastructures able to integrate independent (sub)systems to support their seamless cooperation, even through emergent behaviors. In addition, the continuous servicing process enabled by the recent microservices paradigm leads to rely on evolving approaches able to anticipate, mitigate, or react to unplanned scenarios.

Each system of a SoS must both exist as an independent entity and become part of wider systems when needed. This vision radically changes the notion of "integrated" system:

• - (sub)systems offer limited interaction capabilities and little possibility to be controlled;
• - cooperation can be ad-hoc and only needed in specific cases or conditions;
• - in many cases there is no prior, complete, knowledge of the (sub)systems;
• - SoS behaviors can be partially unplanned to follow environment or requirement changes.

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 System of Systems.

In this context, specific emphasis to methods and approaches focusing on ensuring desired sets of quality attributes (e.g., reliability, security, resilience) that SoSs must satisfy is given.

In addition, research works on distributed and adaptive system are also subject of interest for the GAUSS Workshop. Indeed, topics on dynamic modules integration, autonomous reaction to unplanned scenarios, or dynamic evolution of operational and managerial assets are source of changes that often potentiallyaffect the overall environment (i.e. the SoS) too, consequently they are in the scope of the workshop too.

The GAUSS workshop will accept regular papers reporting on new research, and presentations of Journal First Papers.

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

Topics

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
• Interaction Platforms enabling heterogeneous entities participation
• Knowledge bases integration support and exploitation for semantic interoperability
• Autonomic coordination, negotiation and interactions for MultiAgents and Complex systems
• Blockchain technology for distributed and heterogeneous systems
• Internet of Things-based SoSs
• Adaptive and Reactive systems

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 2020 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 EasyChair submission site.

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

• - LaTex Package (use bare_conf.tex) (ZIP)
• - Word Template (DOCX)

Publication

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 First

This year GAUSS will have 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 1^st, 2019 and August 3^rd, 2020 can propose their work to the JF Track of GAUSS. The proposed papers must be in the scope of the workshop; furthermore, they must not be an extension of previous Conference/Workshop papers, and they must have not already been presented in similar JF tracks.

Journals are eligible for the JF track if they:

• - are indexed on Scimago
• - are in subjects areas and categories related to the workshop (e.g., Computer Science, Software, Artificial Intelligence, etc.)
• - have an average evaluation of Q2 (or more) in the last 4 years (2015-2018) in these categories

Please note that the papers in the JF 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.

Submissions Rules

Authors should submit an electronic record (written in English) in PDF using the easychair submission site.
Each record submission for the JF 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]

Presentation

All the papers accepted to the JF Track will have a presentation slot to promote their work during GAUSS 2020. 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 JF Track implies that at least one of its proponents must register (paying the requested fee) and attend the conference for giving the presentation.
