[Apologies if you receive multiple copies of this announcement] Journal of Software: Evolution and Process CALL for PAPERS Special Issue on Distributed Complex Systems: Governance, Engineering, and Maintenance *Deadline extended to 14th of March* Distributed Complex Systems (e.g., Systems of Systems - SoSs) are gaining momentum due to the widespread adoption of Internet of Things (IoT) tech- nologies and the increasing interest for smart cities, digital twins, and industrial cyber physical systems. The heterogeneity and large scale of these systems re- quire novel design techniques, architectures and software infrastructures able to integrate independent (sub)systems to support their seamless cooperation and to address their 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 part of a Distributed Complex System can both exist as an indepen- dent entity and become part of wider systems when needed. This vision radically changes the notion of “integrated” system: (a) (sub)systems offer limited inter- action capabilities and little possibility to be governed by other entities; (b) cooperation can be ad-hoc and only needed in specific cases or conditions; (c) in many cases there is no prior, complete, knowledge of the (sub)systems; (d) the behavior can be partially unplanned to follow environment or requirement changes. The goal of this Special Issue is to bring together researchers and practition- ers working on the design, the development, the validation, and the continuous maintenance of Distributed Complex Systems (e.g., SoSs, MultiAgent Systems, Adaptive Systems, Ambient Intelligent Systems). Indeed, topics on dynamic modules integration, autonomous reaction to unplanned or dynamic scenarios, or dynamic evolution of operational and managerial assets are in the scope of this special issue. TOPICS: The list of relevant topics include but is not limited to: - Modeling, design, and engineering of Distributed Complex Systems - Architectures, architectural styles, architecture synthesis and middlewares for Distributed Complex Systems - Foundations and formal methods for distributed complex systems - Coordination and adaptation patterns - Online V&V techniques for functional and non-functional assessment and dependability - Online and offline testing techniques - Context-awareness and context-aware adaptation techniques - Reconfiguration and optimization techniques - Self-* mechanisms - Techniques for extracting behavior models from streams of continuous observations - Applications, experiences, case studies, benchmarking, industrial perspec- tives of Distributed Complex Systems - Distributed software engineering: strategies, processes, evaluation and methods - Models of functional and non functional requirements, context and gover- nance policies to support integration of Distributed Complex Systems - Knowledge management and decision-making process in Distributed Com- plex Systems - Ambient intelligent and multi-agent systems - Interaction platforms enabling heterogeneous entities participation - Knowledge bases integration support and exploitation for semantic inter- operability - Autonomic coordination, negotiation and interactions for multi-agent and complex systems - Blockchain technology for distributed and heterogeneous systems - Internet of Things-based Distributed Complex Systems - Adaptive and reactive Distributed Complex Systems IMPORTANT DATES (UPDATED!) - Papers Submissions: 14 March 2021 - First Notification: 30 May 2021 - Revised papers Submission: 15 July 2021 - Final Notification: 30 August 2021 SUBMISSION GUIDELINES: Authors should prepare their manuscript according to the Author Guidelines for the journal "Software: Evolution and Process", and that are available at: https://onlinelibrary.wiley.com/page/journal/20477481/homepage/forauthors.html . The manuscripts and any supplementary material should be submitted through the editorial system at: https://mc.manuscriptcentral.com/jsme. By following the submission instructions, please select “Distributed Complex Systems: Gover- nance, Engineering, and Maintenance” when required by the system. All the papers will be peer-reviewed following the reviewing procedures in place for the journal “Software: Evolution and Process”. Submitted manuscripts should not have been published previously nor be under consideration for publication elsewhere. If the submission is an extended work of a previously published conference or workshop paper, you must sub- mit a cover letter detailing (1) the “Summary of Differences” between the Conference/workshop paper and extended version paper, (2) a clear list of “new and original” contributions in the extended version paper (identifying sections where they are proposed/presented), (3) confirmation of the percent- age of new material (at least 30%), and (4) the related previously published conference/workshop papers.
