Source: R/AHP.R
AHP.Rd

AHP is a multi-criteria decision analysis method developed by Saaty, which can also be used to determine indicator weights.

Usage

AHP(A)

Arguments

A

a numeric matrix, i.e. pairwise comparison matrix

Value

a list object that contains: w (Weight vector), CR (Consistency ratio), Lmax (Maximum eigenvalue), CI (Consistency index)

Examples

A = matrix(c(1,   1/2, 4, 3,   3,
             2,   1,   7, 5,   5,
             1/4, 1/7, 1, 1/2, 1/3,
             1/3, 1/5, 2, 1,   1,
             1/3, 1/5, 3, 1,   1), byrow = TRUE, nrow = 5)
