Abstract:

[A]Abstract. The multiple criteria group decision-making problem involves a set of feasible alternatives that are evaluated on the basis of multiple, conflicting and noncommensurate criteria by a group of individuals. This paper is concerned with developing a GIS-based approach to group decision-making under multiple criteria. The approach integrates, within a raster GIS environment, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Borda`s choice rule. TOPSIS orders the feasible alternatives according to their closeness to the ideal solution. It is used to derive the individual preference orderings. Borda`s method combines the individual preferences into a group preference or consensus/compromise ranking. The approach is implemented within the IDRISI GIS and illustrated on a hypothetical decision situation.
