“…If the value of the crisp number from each criterion is more than the threshold limit, the criterion would be consistent. If the crisp number is less than the threshold, the criterion is ignored (Habibi et al, 2015).…”

“…This technique, to achieve consensus, does not use several rounds processes, and instead, the DM committee has defined a threshold to evaluate the values of reliable threshold limit from the average expert's opinions for choosing effective criteria (Hsu et al, 2010; Kuo & Chen, 2008). If the crisp amount of each criterion is higher than the threshold, this means that experts have reached a consensus on assessing the impact of this criterion (Habibi, Jahantigh, & Sarafrazi, 2015).…”

Development of optimal water supply plan using integrated fuzzy Delphi and fuzzy ELECTRE III methods—Case study of the Gamasiab basin

This paper presents a novel method for the development of an optimal water supply plan showcased using data from the Gamasiab basin, located in Kermanshah province, Iran, concerning new dams that are being constructed in this semi-arid region. In this paper, a new group multi-criteria decision-making (MCDM) plan is proposed by combining two MCDM methods based on the fuzzy Delphi and fuzzy ELECTRE III methods that convert the experts' opinions to triangular fuzzy numbers based on the level of uncertainty associated with various quantitative and qualitative criteria. Considering the opinions of four non-stakeholder experts and data analysis using the fuzzy Delphi method, the criteria were evaluated. Then, by analysing the results using the fuzzy ELECTRE III method, the final ranking of scenarios is obtained. A sensitivity analysis was conducted to assess the effect of uncertainty on the performance of the decision-making system in scenarios ranking. The total expense, flood control, reservoir capacity and diversion and water transfer played a significant role in selecting the optimal scenario. Additionally, a hydrologic model was developed to evaluate the performance of the optimal scenario in terms of qualitative criteria. The data indicated that there was a good agreement between the results obtained from the hydrological model and the scenario ranking by the employed method. Altogether, a comparison of the proposed method with other MCDM methods, including fuzzy analytic hierarchy process and fuzzy technique for order preference by simulation of ideal solution, indicated that the results of the employed method matched more closely to the local experts' opinion.

“…Twenty-five papers were selected based on the search aimed at finding scholarly works that were most closely related to pedagogical models and learning design. Based on Gráinne Conole"s approach to associating relationship to pedagogy or learning theory, the objective is to expand the results of her literature review of pedagogical strategies of learning design to the context of the development for L@S that is constructively aligned to the TCF [16]. After careful consideration, this comprise of perspective, approach, characteristics, and type of approach which can be inclusive of models, frameworks, and application in the context of online delivery in the existing review.…”

“…Some of its weaknesses (repetitive surveys which are cost-and time-consuming, inconsistency in the assessment of experts' opinions affects the result of calculations [55], low convergence in retrieving outcomes, loss of important information, and a lengthy progress of investigation [56]) can be reduced or even eliminated using the upgraded version of Delphi, the FDM. Using fuzzy sets is…”

To improve the supply chain performance in all three aspects of sustainability (social, economic, and environmental), a comprehensive sustainable performance measurement system that captures all the supply chain partners’ efforts and commitments is required. Warehouse, as the second largest logistics source of environmental pollution in the supply chain has been almost completely overlooked and ignored in the past studies. To fill this gap, a warehouse performance metrics framework for environmental and social performance measures was proposed using a novel Fuzzy Delphi and Best-worst methodological approach. The method is less time-consuming than the Analytic Hierarchy Process or Analytic Network Process, it does not address whether criteria are dependent or independent, requires fewer comparisons of criteria, but still produces reliable and credible results. The presented framework consists of 32 equally formulated environmental and social performance indicators, including formulas and measurement units. The 14 most important indicators are ranked according to the requirements of different stakeholders.
