Multi-scale modelling for simulating marine activities under heterogeneous environmental constraints

Abstract

This paper describes the concepts behind the implementation of a multi-agents model aimed to explore how marine activities respond to various environmental constraints. The methodology takes advantage on a responsive agent-based structure, and treats the environment as a set of forcing variables (biophysical, socio-economic and regulatory data). A first experiment in the Iroise Sea area shows a great potential in assessing the intensity and the variability of marine activities at different scales level. The whole methodology is presented in this paper in order to completely analyze the contributions and limitations concerning the SIMARIS prototype. RESUME. Cette contribution décrit les concepts associés à la mise en oeuvre d'un modèle multiagents simulant le déroulement d'activités marines sous contraintes d'environnement. La méthodologie proposée se base sur un environnement de simulation permettant d'intégrer des données spatio-temporelles multi-sources et multi-échelles au sein d'un modèle à base d'agents contraints.Un premier prototype développé en mer d'Iroise montre les apports possibles de cette démarche pour évaluer la variabilité des activités de pêche à différentes niveaux scalaires.

Simulation of marine activities by coupling Geographical Information System and Agent Based Model: improvements and technical achievements

“…If the simulation has been launched in a wider area and for a longer period (lower spatial resolution and higher temporal granularity), aggregated results would have been produced. More details about agents actions and interactions, aggregation processes and multi-scale organization of SIMARIS model are given in Minelli et al (2016).…”
