calculateWeights_old_methods-methods function

Function to calculate fuzzy weights based on comparison matrix using older approaches

This functions calculates FuzzyWeights

based on input fuzzy pairwise comparison matrix.

calculateWeights_old_methods(comparisonMatrix, type = "Chang")

## S4 method for signature 'FuzzyPairwiseComparisonMatrix'
calculateWeights_old_methods(comparisonMatrix, type = "Chang")

Arguments

• comparisonMatrix: object of FuzzyPairwiseComparisonMatrix
• type: A "character" representing type of method used for weights or fuzzy weights determination. Currently implemented methods are "Chang", "Wang" and "Tesfamariam". The default value is "Chang".

Returns

FuzzyWeights. If fuzzy weighting vector is to be obtained please see calculate_weighting_vector function.
