“…Selecting a suitable technological technique for wastewater treated disinfection is always associated with different multiobjective and hierarchy features [19]. The first phase of the Delphi-AHP process has been exploration of the disinfection treatments and criteria under discussion between experts.…”

This paper presents an application of the Analytical Hierarchy Process (AHP) by integrating a Delphi process for selecting the best sustainable disinfection technique for wastewater reuse projects. The proposed methodology provides project managers a tool to evaluate problems with multiple criteria and multiple alternatives which involve non-commeasurable decision criteria, with expert opinions playing a major role in the selection of these treatment technologies. Five disinfection techniques for wastewater reuse have been evaluated for each of the nine criteria weighted according to the opinions of consulted experts. Finally, the VIKOR method has been applied to determine a compromise solution, and to establish the stability of the results. Therefore, the expert system proposed to select the optimal disinfection alternative is a hybrid method combining the AHP with the Delphi method and the VIKOR technique, which is shown to be appropriate in realistic scenarios where multiple stakeholders are involved in the selection of a sustainable disinfection technique for wastewater reuse projects.

Facility location selection is a decision problem that takes into consideration both qualitative and quantitative factors and also is one of the most important strategic decisions affecting organizations in terms of business success. Fundamentally, it comprises evaluating a group of alternative sites on the basis of multiple criteria. In this context when alternatives and factors are multitudinous, multi-criteria decision making methods are being used for successful decisions. In this paper the decision problem is exemplified by applying on a part of a project for a call center site selection by using one of the multi-criteria decision-making methods, namely hierarchy grey relational analysis, based on application of analytic hierarchy process (AHP) and grey relational analysis (GRA) methods. The goal of the selection is to determine the most appropriate location among the alternatives.Nine cities given as alternatives are evaluated and compared against human resources, economic and regional conditions including fourteen sub-criteria.

“…In general, in environmental problems, Analytic Hierarchy Process (AHP), Analytic Network Process (ANP), Elimination Et Choix Traduisant la Realité, (ELECTRE), Multi-Attribute Value Theory / Analysis (MAVT), Multi -Attribute Utility Theory / Analysis (MAUT), Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) (HUANG; KEISLER; LINKOV, 2011) are the most used methods. Zeng et al (2007), Bottero, Comino andRiggio (2011), Kalbar, Karmakar andAsolekar (2012), Hunt (2013), Cornelli (2014), Molinos-Senante et al (2015), Ouyang et al (2015), Castillo et al (2017) and Golfi (2017), are works examples that, through multiobjective analysis, sought the selection of sewage treatment systems for given localities. However, in sanitation management context with focus on water resources protection, it is necessary to adopt a methodology based on watershed territorial cut.…”

In order to determine required wastewater treatment plants (WWTP's) efficiencies, several methodologies have been proposed to assist the sewage treatment systems process selection, usually aiming to achieve economic objectives. However, in water resources problems solving, search involves multiple and conflicting objectives. This work used, for Pardo's river basin (Espírito Santo State, Brazil), water quality simulation model, optimization technique and multiobjective analysis for selecting sewage treatment systems, taking into account Brazilian environmental effluents Biochemical Oxygen Demand standards, imposed by CONAMA Resolution 430/2011. After proposing an optimization model that allowed the estimation of minimum organic matter removal efficiencies, a multiobjective analysis was applied by using the ELECTRE III method, which selected sewage treatment systems for localities responsible for domestic wastewater disposal in Pardo's river basin. The results indicated that keeping the effluents standards can produce treatment plants overestimation and inadequate allocated financial resources distribution for sewage treatment plants implementation. Treatment systems such as Submerged Aerated Biofilters (with Nitrification), Wetlands and Facultative Ponds were the most selected, considering different contexts appreciated in this work.
