createLogicalPCM {AHPtools}

Simulated Logical Pairwise Comparison Matrix for the Analytic Hierarchy Process

Description

Creates a logical pairwise comparison matrix for the Analytic Hierarchy Process such as would be created by a rational decision maker based on a relative vector of preferences for the alternatives involved. Choices of the pairwise comparison ratios are from the Fundamental Scale and simulate a reasonable degree of error. The algorithm is modified from a paper by Bose, A [2022], doi:10.1002/mcda.1784

Usage

createLogicalPCM(ord, prefVec = rep(NA, ord), granularityLow = TRUE)

Arguments

ord

The desired order of the Pairwise Comparison Matrix

prefVec

The preference vector of length as the order of the input matrix

granularityLow

The Scale for pairwise comparisons; default (TRUE) is the fundamental scale; else uses a more find grained scale, derived from pairwise ratios of the elements of the Fundamental Scale.

Value

A Logical Pairwise Comparison Matrix

Examples

lPCM <- createLogicalPCM(3,c(1,2,3));
lPCM <- createLogicalPCM(5,c(0.25,0.4,0.1,0.05,0.2));
