Weighting of Criteria using AHP
The AHP developed by Saaty (1980) was used to weigh each suitability criterion. Tables 2 to 4 show the pair-wise comparison matrix and the RIW derived for each criterion that belongs to water quality, soil quality, and physical condition, respectively. The derived water and soil quality models were then assigned weights of 0.60 and 0.40 respectively, to generate a suitability map in terms of environmental conditions.
