Waste water treatment technology selection using FAHP and GRA approaches
This paper describes an application of hybrid multi–criteria decision–making (MCDM) technique for the selection of waste water treatment (WWT) technology for treating wastewater. The proposed approach is based on fuzzy analytical hierarchy process (FAHP) and hierarchy grey relation analysis (GRA) technique. The FAHP is used to determine the weights of criteria and then ranking of the WWT technology alternatives is determined by GRA.
