This paper presents the SIEGMAS system (Stakeholders Interactions in Environmental Governance by a Multi-Agent System) designed to simulate interactions between stakeholders in common pool resources in Indian Ocean Islands. This decision support system tool is based on a model allowing the study of the interactions between agents acting on a territory and influenced by economic aspects thanks to an agronomic interface. The work presented here focuses on interactive and dynamic tools we developed in order to provide our system with powerful functionalities for maps' configuration and results interpretation. The purpose of this project is twofold. On one hand, we want to offer a tool devoted to the economists community working on Common Pool Resources. On the other hand, we want to present a computer system solution dedicated to simulations' results interpretation for decision-makers in business and politics.
The initialization at the beginning of all type of simulation is recurring. In the field of multi-agents, spatial environments on a micro or macro scale, or more abstract context, such as mapping out energy sources for example, need often to be modelled. The initialization of these environments wherein evolve agents is generally tedious and time-consuming depending on the fineness of the mesh of the cutting in case of a 2D spatial representation. In this paper, we present MASC (Map Sectors Creator), a user-oriented tool that permits easy initialization through the creation of a mesh directly usable in multi-agents systems simulations platforms. The automation of cutting out maps followed by the generation of directly usable code snippets optimize the working time on initialization and allow to focus on the simulations results and observations.
This article proposes to study the interactions between the stakeholders through the study of management transfers in favor of the Common Pool Resources (CPR). The SIEGMAS model (Stakeholders Interactions in Environmental Governance by a Multi-Agent System) shows the interest of using a multi-agent simulation to build new alternatives to existing approaches in the context of decision support to implement Common Pool Resources governance policies. Agent Based Simulation (ABS) that were used in community complex systems offer an innovative approach to this field of economic and environmental study where non transfer modelling transfers of management has yet been made for all the island territories in the Indian Ocean. This article argues that carries extend the application of this method to the study of interactions between stakeholders in relationship to transfers of management in the others parts of Madagascar and others islands in the Indian Ocean.
