We look forward to meeting everyone at MODELS this year!

Internation workshop on Models and Evolution

Co-located with Models'22 List of accepted papers  

The 16th Workshop on Models and Evolution (ME) 2022 is a satellite event at ACM/IEEE 25th International Conference on Model Driven Engineering Languages and Systems - MODELS

Software artefacts constantly increase in complexity, variety and novelty. Environment and business constraints, user requirements and new insights put additional pressure on their adaptability, availability, reliability and quality: they continuously need to be up to date. But evolution issues are critical, complex and costly to manage. They concern requirements, architecture, design, source code, documentation, integration or deployment. They also typically affect various kinds of models (data, behavioural, domain, source code or goal models). Addressing and managing these varieties of changes is essential. Models and meta-models, the cornerstone of complex software systems’ abstractions, represent a powerful mean for facing software evolution challenges by ensuring a more abstract and expressive modeling of software evolution. They can help and guide software evolution and can enforce and reduce critical risks and important involved resources. The workshop puts the focus on Models and Evolution by considering two main sides: (1) Managing software evolution needs by relying on the high-level abstraction power of models and meta-models. (2) Managing model and metamodel evolution needs and the co-evolution of all related software artefacts by putting attention to their increasing evolution issues as they become primary artefacts.

For this edition, the MODELS conference has the special theme “Modeling for social good” #MDE4SG. We encourage also for our workshop, papers themed around: socio-technical systems, tools with social impact, integrating human values, data science, and intelligent systems. This year’s conference will feature a Best Theme Paper Award spanning across all tracks, so we will propose papers covering this topic as candidate for the final evaluation.

Submission Guidelines

We solicit papers of three main types: research papers, position papers and tool presentations as follows:

  1. Research papers (max. 10 pages including references): These submissions provide novel contributions on topics of the workshop presenting novel ideas, addressing challenging problems, or making practical contributions.
  2. Position papers (max. 5 pages):
    • Work in progress papers by young researchers: These submissions present early work and preliminary research results of young researchers in topics related to the workshop.
    • Visionary papers: We encourage papers proposing visionary and strategic ideas and/or looking for collaborations around international projects. These submissions take a visionary stance to the field describing long term ambitions, visionary technological advancements, paradigmatic changes and research agendas. Note that the ideas presented must be clearly positioned, adequately thought through, and sufficiently documented.
    • Industrial experience: Industrial papers reporting about experiences in the area of models and evolution, novel industrial tools, and positions from industry about experience and/or case studies about managing or putting into practice model-driven software evolution solutions are highly appreciated.
  3. Tool presentations (max. 5 pages): These submissions present (experience with) tools (which may be either research prototypes or commercial tools) that are fully/partially dedicated to supporting model-based software evolution and evolution issues encountered in model-based development.
Contributions: All papers submitted to the workshop should have at least 5 pages and 10 pages for full papers following the same style and format of the main tracks of the Conference. Formatting instructions are available here for both LaTeX and Word users. LaTeX users must use the provided acmart.cls and ACM-Reference-Format.bst without modification, enable the conference format in the preamble of the document (i.e., \documentclass[sigconf,review]{acmart}), and use the ACM reference format for the bibliography (i.e., \bibliographystyle{ACM-Reference-Format}). The review option adds line numbers, thereby allowing referees to refer to specific lines in their comments. Submissions that do not adhere to these limits or that violate the formatting guidelines will be desk-rejected without review. Contributions must be submitted through the ME 2022 EasyChair submission page.

Title: Towards Enterprise Digital Twins

Enterprises are rapidly evolving as complex socio-technical systems that require continuous adaptation regarding a dynamic and uncertain environment. Various stakeholders are involved and deliver continuous knowledge through heterogeneous digital models (systems, processes, organizations, etc.) manipulated with various scientific and engineering environments. This modeling continuum open new opportunities for adaptable and efficient enterprises, but also raise new modeling challenges. In this talk, we explore the use of model-driven engineering to develop and operate enterprise digital twins. The talk covers the current state of the art, and provide concrete implementations for smart trade-off analysis and decision making. Finally, we discuss open challenges and draw a roadmap for the MDE community.


The Workshop on Models and Evolution is a satellite event of MODELS 2022. MODELS, the ACM/IEEE 25th International Conference on Model Driven Engineering Languages and Systems, is the premier conference series for model-driven software and systems engineering, and is organized with support of ACM SIGSOFT and IEEE TCSE. Since 1998, MODELS has covered all aspects of modeling, from languages and methods, to tools and applications. Attendees of MODELS come from diverse backgrounds, including researchers, academics, engineers and industrial professionals. MODELS 2019 is a forum for participants to exchange cutting-edge research results and innovative practical experiences around modeling and model-driven software and systems. This year’s edition will provide an opportunity for the modeling community to further advance the foundations of modeling, and come up with innovative applications of modeling in emerging areas of cyber-physical systems, embedded systems, socio-technical systems, cloud computing, big data, machine learning, security, open source, and sustainability.
