DYNAMICS OF STRUCTURE - AN INDIVIDUAL ORIENTED APPROACH

The dynamics of network structure are considered, here as a consequenc e of individual choices with regard to relationships. We introduce the individual- or object-oriented modelling approach to model social net works. Object-oriented model building is based on acting so-called 'ob jects', communicating with and reacting to each other. Individuals are modelled as objects, each object with the possibility of having speci fic characteristics and behavioral rules. In contrast to many existing studies in the field of dynamic social networks, heterogeneity and de pendence of dyads can easily be dealt with using this method. To clari fy the new approach, we present a first simple model of the arising of friendship networks. For this simplicity, the model presented here is based solely on individuals' different needs for social contact, but can easily be extended. We present results about the effect of the dis tribution of individual needs on the network emergent structure.
