Integration of Gray System Theory with AHP Decision-Making for Wastewater Reuse Decision-Making
Publication: Journal of Hazardous, Toxic, and Radioactive Waste
Volume 25, Issue 3
Abstract
The existence of uncertainties in decision-making has given rise to multicriteria decision-making to achieve results that weigh in the effects of uncertainty. This study presents a method for selecting the best alternative for treated wastewater reuse based on gray system theory (GST). Alternatives and appropriate decision criteria for wastewater reuse are determined by experts. The criteria are weighed with the analytical hierarchy process (AHP) method, and the best wastewater-reuse alternative is then selected based on the evaluation based on distance from average solution for gray water (EDAS-G). Results of an example demonstrate wastewater reuse in the environmental sector receives the highest priority among several alternative uses.
