Analogies between social interactions models and supply chains.
L. Navoret (Université Paul Sabatier)
Biological models turn out to be useful for economical issues and especially for supply chain problems. To this aim, we study sheep herds as a paradigm of social interactions and their expression in collective movements. From an elementary individual based model, we derive a macroscopic model through kinetic (mean-field) model and we show how this macroscopic model can be used to analyse the transition from the dilute to the gregarious phases of the sheep herd. We believe that this kind of model can be translated to the economic field.
