Visual and semi-automated exploration of an archaeological model: calibrating a model of spatial reorganization in North-Western Europe, A.D. 800 to 1100
International audience; Most often, when building a model, the modeller has to choose between two types of methods forevaluating its model. (1) The “face validation”, based on a visual and qualitative assessment of the model outputs, allows for a quick and direct feedback of the model behaviour considering the different values of parameters used. (2) More recently, and to have a more pervasive method of exploration, many modellers leant on High-Perfomance Computing to develop automated ways of exploring models often based on full factorial designs or on more parsimonious methods like genetics algorithms.In this presentation, we advocate for combining the efficiency of the automated explorat…
Construction et évaluation d’un modèle de simulation dans un contexte interdisciplinaire
Le travail présenté ici s’inscrit dans le cadre de l’ANR TransMonDyn, qui vise à étudier les transformations dans les systèmes de peuplement sur le temps long, au moyen de modèles conceptuels ou implémentés sous forme informatique. Cette étude s’appuie sur un formalisme, développé au sein du projet, définissant la transformation comme une transition entre un régime 1 et un régime 2. Le projet TransMonDyn repose sur l’analyse d’un ensemble de douze cas d’études empiriques, les transitions, dont les localisations autant que les échelles spatiales et temporelles sont extrêmement diverses.

SimFeodal: an agent-based model to explore the combined effects of social and demographic changes on the hierarchy of rural settlement patterns in North-Western Europe during the Middle Ages
International audience; In North-Western Europe, regional settlement patterns that were dispersed in 800 CE became much more concentrated and hierarchical in 1200 CE (Tannier et al. 2014). This phenomenon occurred in all regions but the resulting level of concentration and hierarchy of settlement patterns differed notably among the regions. Several processes jointly explain this major transition (Cura et al. 2017). •The dismantling of the Carolingian Empire and the dissipation of powers induced struggles among lords and thus a rise in violence. The result of this was the creation of castles as well as an increase of the need of protection for peasant households•The militarisation of the soc…
