Development of fuzzy multi-criteria approach to prioritize locations of treated wastewater use considering climate change scenarios.

摘要: Abstract This study proposed a robust prioritization framework to identify the priorities of treated wastewater (TWW) use locations with consideration various uncertainties inherent in climate change scenarios and decision-making process. First, fuzzy concept was applied because future forecast precipitation their hydrological impact analysis results displayed significant variances when considering long periods (e.g., 2010–2099). Second, multi-criteria decision making (MCDM) techniques including weighted sum method (WSM), Technique for Order Preference by Similarity Ideal Solution (TOPSIS) TOPSIS were introduced different MCDM methods philosophies. Third, under complete uncertainty (DMCU) maximin, maximax, minimax regret, Hurwicz, equal likelihood used find final rankings. is then Korean urban watershed. As result, rankings obviously appeared between non-fuzzy MCDMs WSM TOPSIS) inter-annual variability effectiveness considered only TOPSIS. Then, prioritizations derived based on 18 from nine decadal RCP4.5 RCP8.5. For more rankings, five DMCU approaches using derived. combining can be rendered less controversial among stakeholders changing environments.
