نبذة مختصرة : International audience ; The objective of this project is to produce knowledge about hybrid food systems positioned between short and long circuits, addressing their economic, social, and environmental performances and the conditions of their sustainability, to co-construct with p roject partners a method and support tools for their sustainable development. These systems are particularly complex, with interactions between actors, interactions between performance indicators of various kinds, new vocabulary and new practices centered on human relationships, with very little formalization. To tackle this problem, we propose a new system engineering approach based on meta- modeling to consider the flow, the requirements and performance indicators. After presenting the problem, we will det ail our approach and its implementation. We will end with a review and perspectives.
