CORMAS: COmmon-pool Resources and Multi-Agent Simulations

Welcome to Cormas !

This website is the former Cormas VW site. A new site is now available: https://cormas.org, which offers a version of Cormas running on Pharo. CORMAS is an Agent-Based Modelling (ABM) platform tailored preferentially to renewable resource management. Cormas is intended to facilitate the design of ABM, as well as monitor and analyse simulations. It is based on the VisualWorks programming environment which enables the development of models in Smalltalk. Cormas is a framework from which, by specialization and refining, users can create specific entities for their own model. - CORMAS is a free Open Source Software. Its last release (06/2025) can be downloaded here. As VisualWorks development has been discontinued, this version of Cormas only runs on Windows.                                 The main interface of Cormas - On this site, you will also be able to access application examples (with a models library) and publications. - We propose a Companion-Modelling approach (ComMod) based on a computer tool,                                 A ReHab session at IUCN 2021, with Cormas

Training courses on modelling

We are regularly delivering modelling training courses.

International Summer School on ABM:

• These training courses are held regularly in Montpellier, France at Agropolis International.
• By taking part in this course, you will gain a modelling culture and learn the different skills required for building agent-based models (ABMs) applied to sociological, ecological, or socio-ecological systems.

• Key points
  
• MISS-ABMS is multi-cultural in terms of background and nationalities of the trainers and participants
• MISS-ABMS promotes a collaborative practice of modelling and simulation
• MISS-ABMS is multi-platform: Cormas, Gama or NetLogo can be choosen
• MISS-ABMS presents the different stages of an ABM process, with a focus on model design and implementation
• MISS-ABMS offers a significant time for group work to design and implement an ABM (see the leaflet or watch the presentation video).
• For who
  
• Each year we enjoy having participants with very heterogeneous profiles in terms of age, nationality, scientific background and experience in modelling or coding. Beginners in ABM who are planning to participate in a modelling project in the months following the training are welcomed.
• If you have any concern regarding your participation, feel free to ask at:
  miss-abms_organizers[at]agropolis[dot]fr
• Information and registration
  
• For more details see the summer school website: https://www.agropolis.fr/MISSABMS

Last papers on Cormas

• A new tutorial on tools for designing graphical interfaces is available.

This site, developed by the Green research unit (now called UMR SENS) from CIRAD, is devoted to the applied modelling of relationship between societies and their environment.You will find here what we and our partners are using ABM for the natural resources management.
