New TOPSIS: Modification of the TOPSIS Method for Objective Determination of Weighting

Subjectivity in the determination of criteria weights in the TOPSIS method can have a significant impact on the final result and reliability of the decision taken.When weights are determined subjectively, the decision depends heavily on the preferences of the individual or group assigning the weights, which may not always be objective or consistent.The Objective Weighting-TOPSIS (OWH-TOPSIS) method is a modification of the TOPSIS method that incorporates an objective weighting approach to determine criteria weights objectively.This approach aims to improve accuracy and consistency in determining criteria weights by considering decision makers' preferences and variations in data.OWH-TOPSIS can provide evaluation results that better suit the preferences and needs of decision makers, while considering the unique characteristics of the data being evaluated.This approach can be a powerful solution in complex multi-criteria decision-making, by producing more accurate and relevant alternative rankings.Although the OWH-TOPSIS approach can be used to determine the weights, this process can require complete and accurate data and a deep understanding of the decision maker's preferences.The comparison results show that the correlation value of the entropy-TOPSIS method is 0.725, the correlation value of the OWH-TOPSIS method is 0.714, the correlation value of the CRITIC-TOPSIS method is 0.714, and the correlation value of the OWH-TOPSIS method is 1.
