Application of novel intuitionistic fuzzy BWAHP process for analysing the efficiency of water treatment plant

Abstract

In this investigation, we have put forward a novel multi-criteria decision-making (MCDM) technique, intuitionistic fuzzy best-worst method (intuitionistic fuzzy BWM). Moreover, we have designed a novel hybrid MCDM technique called intuitionistic fuzzy best-worst analytic hierarchy process (intuitionistic fuzzy BWAHP) which is the amalgamation of intuitionistic fuzzy BWM and analytic hierarchy process (AHP). In this study, BWM finds its use to evaluate the weightage (or priority value) of criteria, and using AHP, the local weights of alternatives are decided. The proposed technique is utilized to recognize the most significant alternative (or indicator), for the efficiency of a water treatment plant. Observing the result, it can be said that the 'water quality' is the most responsible alternative. The consistency ratio value which is found by our proposed method is less, compared to the existing BWM and fuzzy BWM techniques. Finally, using a comparative study and sensitivity analysis, we verify the findings produced by our proposed method.

Assessing farmers' perception to Agriculture 4.0 technologies: A new interval‐valued spherical fuzzy sets based approach

“…Ordinary fuzzy sets have been used many times to compare the results of the extensions of fuzzy sets. [118][119][120][121] At this point, one of the most frequently used fuzzy sets is triangular fuzzy sets. [118][119][120][121] TFNs are considered as the pillar of the fuzzy set.…”

[118][119][120][121] TFNs are considered as the pillar of the fuzzy set. 122 TFNs are intuitive and easy to use; it is also computationally simple and very useful in promoting representation and information processing in a fuzzy environment.…”

“…Apart from this, it has been seen that the MAIRCA method is usually used with triangular fuzzy sets, which are type 1 fuzzy sets, in problems involving uncertainty. Therefore, in our comparative analysis, triangular fuzzy sets are used because they are more accepted in the literature for comparison [118][119][120][121] and their reliability has been proven with many papers, 102,106,112,122 and also to demonstrate the advantages of using spherical fuzzy sets which is the extension of ordinary fuzzy sets. As a result of the calculations obtained by adopting the steps of the triangular fuzzy MAIRCA method, the total gap matrix is calculated as in Table 12.…”

“…Liu, et al [32] proposed the D-number BWM (D-BWM) weighting model, which is simple and sensitive to subjective information, and is more suitable for realistic decision-making. Majumder, et al [33] presented intuitionistic fuzzy BWM and its combination with AHP, intuitionistic fuzzy best-worst analysis hierarchical process (BWAHP).…”
