Mineral Potential Mapping Via TOPSIS with Hybrid AHP–Shannon Entropy Weighting of Evidence: A Case Study for Porphyry-Cu, Farmahin Area, Markazi Province, Iran

New Approach in Application of the AHP–Fuzzy TOPSIS Method in Mineral Potential Mapping of the Natural Bitumen (Gilsonite): A Case Study from the Gilan-e-Gharb Block, the Kermanshah, West of Iran

“…The integration of AHP and TOPSIS in a fuzzy environment has not been studied in the field of mineral prospectivity modeling in the initial exploration of the natural bitumen deposits. However, there have been several studies on implementing these methods and their combination for exploration of ore deposits such as copper, gold, iron, etc., (Pazand and Hezarkhani, 2015;Asadi et al, 2016;Feizi et al, 2017a;2017b). This paper presents a new technique of combining the proposed methods using MPM in a fuzzy environment and examines this method in this case study.…”

“…Then, the decision-makers calculate appropriate rankings based on the PIS and NIS for alternative locations (i.e., A+ and A). Consequently, the best alternative can be identified as the one with the shortest distance to PIS and the longest distance to NIS (Zyoud et al, 2016;Feizi et al, 2017b). Non-renewable resource exploration strategies have rapidly changed and innovative data processing and data management technologies have grown increasingly (Zyoud et al, 2016).…”

“…AHP-FTOPSIS application is a knowledge-driven technology based on specialist knowledge of spatial relationships and spatial characteristics between the known deposits comprised of geological data collection of deposits. The key idea of this procedure is that the DNS weight is extracted from the AHP in pairs, while the selected target area with the FTOPSIS should be as close as possible to the ideal positive solution and as far as the negative ideal solution is concerned (Feizi et al, 2017b).…”

“…Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) is another method that is usually used as a comparing approach in parameters (Dagdeviren et al, 2009;Awasthi et al, 2010;Abedi and Norouzi, 2016;Asadi et al, 2016;Feizi et al, 2017b). To achieve the advantages of these two methods, this paper applies a combination of both AHP-FTOPSIS with a focus on mapping the high-potential zones of natural bitumen mineralization in the Zagros fold-thrust belt, which is a few known for natural bitumen deposit occurrences.…”

Group decision making process for early stage evaluations of infrastructure projects using extended VIKOR method under fuzzy environment

“…Secondly, the paper determines criteria weights integrating subjective and objective weighting methods. The combined weighting has been applied in decision making literature [4][5][6], however it has never been applied regarding the project evaluation. Subjective weighting leans on decision maker's judgment, while objective weighting leans on strict mathematical calculations performed over ratings of alternatives.…”
