An integrated trapezoidal fuzzy FUCOM with single-valued neutrosophic fuzzy MARCOS and GMDH method to determine the alternatives weight and its applications in efficiency analysis of water treatment plant

This paper aims to introduce the Trapezoidal Fuzzy-Full Consistency Approach- Single Valued Neutrosophic Fuzzy-Measurement Alternatives and Ranking according to the Compromise Solution- Group Method of Data Handling (TrF-FUCOM-SVNF-MARCOS GMDH) as a novel subjective weighting hybrid method. Use, in order to determine the criteria weights, becomes made of TrF-FUCOM in the model proposed. Using the weights of criteria SVNF-MARCOS is employed to evaluate the rank of the set of alternatives. Via using the weighted value of the alternatives, an index is created by this proposed method. The priority parameters that are chosen are deployed as GMDH model’s input, and the Index value as an output. The data had by the output are transformed through the using of Arc Tangent function, and both the GMDH and the combinatorial training algorithms are used to train the model. This innovative hybrid approach is made use of for the purpose of pinpointing the crucial element in a water treatment plant's efficiency analysis. The findings show that the most crucial factor for increasing WTPs' effectiveness is the altering of the weather pattern.
