COUPLING THE FARMING SYSTEM MODELLING TOOL 'OLYMPE' WITH THE MULTI-AGENT-SYSTEM SOFTWARE SYSTEM 'CORMAS' TO UNDERSTAND THE USE OF RESOURCES IN COMPLEX AGRICULTURAL SYSTEMS

摘要

This paper describes how the farming system modelling software 'Olympe' (developed in collaboration by INRA/CIRAD/IAMM) can be coupled with the agent-based simulation platform 'Cormas' to better characterize and analyse farming systems identified as major centres of decision in agriculture. Cormas (developed by CIRAD) enables representation of complex situations and takes into account interactions between different stakeholders. First we describe the two models and the potential benefits of combining the tools, then we describe how we developed a new platform based on the two software systems, and finally we illustrate how the new platform can be used with a simple example developed for educational purposes. The advantages and limits of this type of approach are discussed along with possible further developments.
