“…We can use different criteria depending on the specific characteristics of each leachate, the plant's capacity, the technologies applied, the sustainable strategies and the objective of the analysis (Curiel-Esparza et al 2004). The criteria employed in this research work are grouped into four categories:…”

In its composition we find dissolved organic matter, inorganic salts, heavy metals and other xenobiotic organic compounds, so it can be toxic, carcinogenic and capable of inducing a potential risk to biota and humans. European law does not allow such leachate to leave the premises without being depurated. There are many procedures that enable debugging, always combining different techniques. Choosing the best method to use in each case is a complex decision, as it depends on many tangible and intangible factors that must be weighed to achieve a balance between technical, cost, and environmental sustainability. We present a hybrid method for choosing the optimal combination of techniques to apply in each case, by combining a multi-criteria hierarchical analysis based on expert data obtained by the Delphi method with an analysis by the method of VIKOR to reach a consensus solution.Manuscript Click here to download Manuscript: Manuscript.docx 1 2 3 4 5 6 7 8

“…On the other hand, the development of new technologies and the improvement of some of the existing technologies, making them economically competitive, have created major difficulties in selecting an optimal technology for a specific case. The proposed methodology, which integrates the analytic hierarchy process (AHP) with a Delphi technique, provides project managers with a tool to evaluate multi-criteria and multi-alternative problems which involve non-commeasurable decision criteria [10,11]. Other multi-criteria decision analysis techniques (MCDA) have been applied in the field of wastewater infrastructures.…”

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.

“…As such, it is now widely recognized that the use of underground space, both now and in the future, needs to incorporate increased consideration for the need for sustainability and resilience (Curiel-Esparza et al, 2004;Admiraal, 2006;Simpson & Tatsuoka, 2008;Nelson & Sterling, 2012;Sterling et al, 2012). Underground space offers great potential and is a resource that is so far virtually unexploited (Bergman, 1986).…”

This paper reviews the key issues relating to the increased future use of underground space where geoscientific information will be indispensable as a decision support tool for the sustainable development of underground space. A clear understanding of what is in the underground space (geology, utilities etc.) and its properties are required in order to form a correct grasp of the potential assets and challenges of underground space as a resource. To inform urban developmental choices, regions having geological units which lend themselves to development or expansion of underground space use in the future, will be given precedence over those with adverse geological conditions. Such information needs to be included into decision support systems for conventional types of underground construction. This paper establishes that there is a strong need to adopt computational visualization approaches in the form of GIS based Multi Criteria Decision Analysis (MCDA); these provide a platform to enable the testing of underground space through a virtual experimental set-up of different uses, using a broad range of different yet divergent future scenarios to ensure that the core objectives of sustainable development are met.
