INTEGRATION OF THE MULTICRITERIA EVALUATION AND GIS Development of a prototype integrating MapInfo GIS and ELECTRE methods

摘要

Nowadays, GIS constitute powerful tools for manipulation, management and spatial data analysis. But one of the fundamental aspects which will assure their preeminence in decision making processes, in particular those relevant to territory management, is the availability of a set of mechanisms allowing to integrate the decision makers preferences and to make choices in objectives evaluation contexts and conflicting criteria. MuKiCriteria Evaluation MCE is a response for compromise alternative research in complex choice situations. The combination of the possibilities offered by those tools go in the sense of building up a real spatial decision support system. To do this, we opt for the integration of the spatial analysis functions of GIS and the MCE methods. Methods of outranking (partial aggregation) and more precisely the family of ELECTRE procedures are privileged. In this paper, we show the actual limits of GIS in matter of decision-making, and evoke the necessity of MCE procedure integration in GIS. We present conceptual and methodological solutions in view to do this integration. A prototype based on the use of the Maplnfo Professional GIS and ELECTRE type of MCE techniques is presented and illustrated through an application on a realistic case.
