Extensiones al modelo de segregación de Schelling - primera parte -

This article presents the first results of a series of works where propose extensions to Schelling's segregation model, one of the key models in the genesis and development of Agent-Based Models (ABM) and the Systems Theory Complex topics. In this first work the Schelling model is introduced, summarized some of the most relevant extensions that have been proposed so far and are They propose 4 new extensions. To monitor the results of each model use a set of indicators or metrics that allow evaluating the degree of segre- obtained and the trajectory followed in each case. From these exercises it follows a set of results, for example, that the incorporation of individual preferences random, does not necessarily deepen the results in terms of segregation. By On the other hand, the inclusion of a feedback mechanism from which the agents become less tolerant as segregation increases generate dynamics interesting. In this scenario, the reduction in exchange opportunities between different classes/groups/ethnic groups that coexist in the urban space leads to stereotyping mutual stigmatization and stigmatization, giving rise to the formation of small ghettos, even in the presence of initially highly tolerant agents, may trigger a process that end up with a highly segregated urban space with very low levels of tolerance cia between groups. The work uses the programming language R to implement the model, perform simulations and scenario analysis.
