2021 Bellairs CAMPaM workshop 
These pages still contain some material (the schedule, to give you an impression) of the 2019 workshop and will be updated soon !

Welcome to the home page of the 17th CAMPaM workshop.

The workshop aims to further the state-of-the-art in Computer Automated Multi-Paradigm Modelling (CAMPaM) - a name (though Hans preferred "Aided" to "Automated") coined by Pieter Mosterman and Hans Vangheluwe in the late '90s - as well as to define future directions of this emerging research area by bringing together world experts in the field for an intense one-week workshop.

The workshop will be held Saturday 20 (arrival) - Saturday 27 (departure) February 2021 at McGill University's Bellairs campus. The actual workshop starts on Sunday morning and continues for 5 full days (until Thursday evening). Although it is possible to depart on Friday, most participants leave on Saturday to do some sightseeing on Friday (in particular, to visit Crane Beach).
The workshop takes the Dagstuhl seminar format --bring a critical mass of top researchers together in a relatively remote location and soon new ideas will flow-- one step further: the Bellairs facilities are relatively primitive (and cheap) and there are no distractions such as typically found in hotels.


Workshop Subject

Computer Automated Multi-Paradigm Modelling (CAMPaM)

CAMPaM acknowledges that explicit modelling is the central activity in and main enabler for the analysis and design of complex systems. Because of the heterogeneous nature of for example embedded systems and the many implementation technologies, Multi-Paradigm Modelling is a critical enabler for holistic design approaches (such as mechatronics), to avoid overdesign and to support system integration. Multi-paradigm techniques have been successfully applied in the field of software architectures, control system design, model integrated computing, and tool interoperability. Fifteen CAMPaM workshops at Bellairs '04, '05, '06, '07, '08, '09, '10, '11, '12, '13, '14, '15, '16, '17, '18, '19, many Multi-Paradigm Modelling (MPM) conference sessions and MoDELS '06 (Genoa), '07 (Nashville), '09 (Denver), '10 (Oslo), '11 (Wellington), '12 (Innsbruck), '13 (Miami), '14 (Valencia), '15 (Ottawa) workshops have been held. A special issue of the ACM Transactions on Modeling and Computer Simulation (TOMACS) was devoted to CAMPaM, and COST Action IC1404 "Multi-Paradigm Modelling for Cyber-Physical Systems" (MPM4CPS) worked 2014 - 2019 on MPM solutions for the design of complex, Cyber-Physical Systems. See also the (very outdated) CAMPaM page for more related material.

The networking of multi-physics (mechanical, electrical, hydraulic, biochemical, ...) with computational systems (control systems, signal processing, logical inferencing, planning, ...) processes, interacting with often uncertain environments, with human actors, in a socio-economic context, leads to so-called Cyber-Physical Systems (CPS). Multi-Paradigm Modelling aims to tackle the kind of complexity found in CPS and CPSoS (Cyber-Physical Systems of Systems). In the context of Production Systems, MPM can furthermore be used to address the problems typically found in Industry 4.0. In particular, it can be a basis for representing and "slicing" a Digital Twin.
Multi-Paradigm Modelling adresses and integrates several orthogonal research dimensions:
  1. model abstraction, concerned with the (refinement, generalization, ...) relationships between models at different levels of abstraction;

  2. multi-formalism modelling, concerned with the coupling of and transformation between models described in different formalisms. At the language level, this entails (modular) Modelling Language Engineering (MLE).

  3. explicitly modelling the workflows of multi-paradigm activities.
To support the above, the following enabling theories/methods/technologies are considered crucial:
  1. Modular Modelling Language Engineering (MLE) and in particular meta-modelling, concerned with the description (models of models) of classes of models as well as the explicit modelling of language semantics, possibly by specifying the orchestration of existing simulators/executors/analysers. Taking meta-modelling one step further, the structure, look, and behaviour of complete formalism-specific modelling environments should be specified and the modelling/simulation/execution/analysis/debugging/... environments automatically synthesized.

  2. the explicit modelling of transformations, treating transformations as first-class models. This leads quite naturally to questions about (meta-)model evolution, higher-order transformations (transforming transformations), co-evolution of models, multi-view modelling and syntactic and semantic model consistency.
CAMPaM explores all possible combinations of the above notions. It combines, transforms and relates formalisms, generates maximally constrained domain- and problem-specific formalisms, methods, and (visual) tools, and verifies consistency between multiple views.

Workshop High-level Goals
  1. The diversity in the research subjects of the attendees provides a fertile ground for cross-correlating research. In particular, since 2008, several of the workshop participants are not Computer Science researchers, but rather domain-experts (mechanical engineering, embedded systems, ...). The result of this interaction will be the application of methods and techniques that are well-known and established in different fields of research (such as meta-modelling, graph transformation, domain-specific modelling, visual modelling environments and component-based modelling) and will lead to cross-disciplinary collaboration. Furthermore, it should make evident the need for advances of research along avenues otherwise overlooked.

  2. A concerted effort of the attendees will result in a consolidation of scattered CAMPaM-related work as well as a common vision on how to best evolve the field of CAMPaM. This vision will include detailed technical perspectives, joint publications, how Multi-Paradigm Modelling and Model-Driven Engineering may be introduced in education, as well as organizational plans.

Workshop Focus
This year, we plan to focus on (some of) the following subjects during the workshop. The actual topics are decided at Bellairs during the first day of the workshop based on the particular interests of the participants.
  1. A rigorous definition of "Multi-Paradigm" and foundations of Multi-Paradigm Modelling. This is a continuation of the efforts during the MPM4CPS COST Action, of work at the 2019 CAMPaM workshop, and of the many miniCAMPaM workshops that were held in Paris, Antwerp, Aachen and Karlsruhe, by the "MPM theory" group. This year, we want to in particular look at the link between foundations and tooling.
  2. Foundations of domain-specific modelling with a particular focus on "blended" textual/visual modelling and the modelling/formal analysis/simulation/synthesis of complex user interfaces. Of particular interest is support of "early stage" inter-disciplinary modelling (aka "sketching" or "ideation"). This can for example be achieved by relaxed conformance checking (also known as "a posteriori typing") and the explicit modelling of when which conformance checking needs to be done.
  3. Implicit vs. explicit modelling, which acknowledges that efficient communication (between humans, and between human and computer) often is possible thanks to a lot of implicit knowledge shared by sender and receiver. Sometimes however (part of) the semantics of a modelling language needs to be made explicit as failing to do so means that one of the parties may make wrong assumptions about semantics.
  4. The relationships between systems/models and their context of validity. This further develops Zeigler's notion of Experimental Frame (further developed by Traoré and Muzy) into Experiment Frames and Validity Frames and develops validity-frame aware development processes. This relates to the design of modelling languages and model libraries which contain not only systems models but also explicit models of the context in which these models may be meaningfully (re-)used.

Since 2011, we mostly, in addition to a few general presentations, work in small groups (as few as 2 participants) on specific problems. The results are discussed during the plenary evening sessions (7-10pm). Such focused discussion are likely to lead more directly to joint publications.
