The IODA methodology allows automated construction of models from an ontology, consisting of generic interactions that we can assign to families of agents. Thanks to the measurement tools that we define in this paper, we can automatically qualify characteristics of the underlying models. Then we propose building of a browser for viewing and analysing several simulations at the same time. This browser, called LEIA for "LEIA lets you Explore Interactions for your Agents", aims at exploring the simulations space. Finally, we offer tools for processing and simplifying model, allowing iterative construction of new models by involving the user in their assessment.
