In the past, decision making within the energy sector, especially in Iran, was limited to economic analysis. Lately, multiple criteria decision making has gained great popularity. However, this is not enough to make a right decision by considering sustainability. This paper deals with designing an appropriate multiple criteria decision making method to address the multifaceted nature of such problems. This task is the second precondition to make a decision which meets the sustainability criterion. This is done by revealing new facts about quantitative and qualitative data and the degree of compensation between the criteria. Moreover, this paper illustrates the capability of different methods... 

The objective of present study is to analyze the dynamic modeling of bioelectrochemical processes and improvement of the performance of previous models using quantitative data of bacterial transport parameters. The main deficiency of previous MFC models concerning spatial distribution of biocatalysts is an assumption of initial distribution of attached/suspended bacteria on electrode or in anolyte bulk which is the foundation for biofilm formation. In order to modify this imperfection, the quantification of chemotactic motility to understand the mechanisms of the suspended microorganisms’ distribution in anolyte and/or their attachment to anode surface to extend the biofilm is implemented... 

Floating urbanization could be the subject of a green flood mitigation strategy. The main part of any floating house is the buoyant part, which is made from concrete pontoons. Aggregates play the most important role in making concrete a lightweight material. Oil Palm Shell (OPS) is an agricultural waste material, which is widely available in South East Asia. This study tries to select the best cementing material from waste and produced pozzolans, to improve the specifications of green lightweight concrete with Oil Palm Shell (OPS), using decision-making methods. The decision making model was conducted by the application of a Fuzzy Preference Selection Index (PSI). Quantitative data was...
