Analytic Hierarchy Process (AHP) Applications in Watershed Management Plan, A Case Study of Sub-Watershed

Abstract

Analytical Hierarchy Process (AHP) one of the Multi-Criteria Evaluation techniques is proposed by Saaty’s-1980. More than one parameter is equally important for management, as these are very much interrelated. One of the methods is AHP, which is welcomed for supporting procedural justice that regards clearness and equality of decisions. However, the AHP method promises for procedural justice are partly grounded in it is supposed by numerical accuracy. By contrast, AHP method can contribute to the multiple criteria for procedural justice, which may explain AHP’s continuing and growing popularity. The actual process of applying the decision rule is evaluation. In order to meet a specific objective, several criteria need to be evaluated. Such a procedure is termed as AHP. The integration of special information technology and multi-criteria methods facilitate the provision of a tool with great potential for obtaining watershed boundary or selecting sites for taking action plan. AHP provides an appropriate framework for the application of multi-criteria evaluation methods, whereas multi-criteria evaluation techniques add to GIS the means of performing trade-offs on contradicting objectives, giving weight-age to both multiple criteria as well as the knowledge of the decision maker.
