Proposal for a Spatial Decision Support System in Territory Planning: a Hybrid Approach: Linear Programming, Fuzzy Measurement, Multicriterion Methods and Gis

Our study falls under the perspective which aims at optimizing the quality of decision brought to the spacetime decision-making process. Our aim is to claim with an extensible, generic, deterministic and multicriterion model based on the axiomatic of models representing decision strategies and authorizing interaction between criteria. The suggested approach is constructive, interactive and based on uncertainty theories (fuzzy logic, possibility theory, fuzzy integrals) and linear programming. We define a new approach as well for the description of available information as for their use and suggest replacing the additivity property in the performance aggregation phase by a more reliable property: the growth using nonadditive aggregation operators resulting from the capacity theory and largely known as fuzzy measurements. The latter allow evaluating space compatibility between the available data by defining a weight on each subset of criteria and fuzzy integral, more specifically; the Choquet's integral is an aggregation operator able to consider the interaction among these criteria.We elaborate, in this paper a spatial decision support system. The latter is based on a combined use of Geographical Information Systems (GIS) and Multicriterion Analysis Methods namely the (ordinal and nominal) sorting approaches to claim the territorial (spatial) context analysis. This study allows the professionals to carry out a diagnostic and proposes adapted actions in the resolution of two Territory Planning problems: The first relates to the search of a surface better satisfying certain criteria and the second consists in realizing the land use plan.
