ahp.pwerror: Finds the pairwise comparisons with the maximum amount of inconsistency

Description

After constructing a list of matrices with \(\epsilon_{ij} = a_{ij}w_{j}/w_{i}\) (following ahp.error), this algorithm extracts the top n numbers of pairwise comparison matrices with the highest \(\epsilon_{ij}\) for each decision-maker.

Usage

ahp.pwerror(ahpmat, atts, npw = 3)

Arguments

ahpmat

A list of pairwise comparison matrices of each decision maker generated by ahp.mat.

atts

a list of attributes in the correct order

npw

Number of pairwise comparisons

Value

A list of matrices containing \(\epsilon_{ij} = a_{ij}w_{j}/w_{i}\) for each decision-maker, with elements from the lower triangle set as NA automatically (since it is essentially equal to the element in the upper triangle).
