A spatial microsimulation of population dynamics in Southern France: a model integrating individual decisions and spatial constraints
نویسندگان
چکیده
The aim is to model the spatial distribution of the population dynamics in Southern France. First the philosophical differences between a micro-level approach and a meso-level approach are presented and their respective advantages are briefly compared from a general point of view. Then the model is presented. It is a microsimulation model but it has some rules defined at the aggregate level of the communes. Change occur through events as birth, death and migration, that depend on probabilities that are linked to different individuals characteristics as sex, age etc. Four scenarios of development are tested and some future improvements are proposed. RESUME: L'objectif est de modéliser la distribution spatiale de la dynamique de population dans les départements du Gard et de l'Hérault. Après une discussion préliminaire sur les questions d'échelle de la modélisation, un modèle de microsimulation intégrant à la fois des règles définies au niveau des individus et des agrégats spatiaux est présenté. Le moteur du changement est déterminé par des événements tels que les naissances, les décès, les migrations dont les probabilités sont tabulées par rapport à des caractéristiques individuelles (sexe, âge,...). Quatre scénarios d'évolution sont testés, et enfin des prolongements sont proposés. KEY-WORDS: dynamic modelling – microsimulation – settlement system – spatial analysis MOTS-CLES: modélisation dynamique microsimulation système de peuplement analyse spatiale.

متن کاملAnalysis of crime patterns through the integration of an agent-based model and a population microsimulation
Please cite this article in press as: Malleson, N., microsimulation. Computers, Environment and U In recent years, criminologists have become interested in understanding crime variations at progressively finer spatial scales, right down to individual streets or even houses. To model at these fine spatial scales, and to better account for the dynamics of the crime system, agent-based models of c...
