In RMCDA: Multi-Criteria Decision Analysis

Apply Additive Ratio Assessment (ARAS)

Description

Apply Additive Ratio Assessment (ARAS)

Usage

apply.ARAS(mat, weights, beneficial.vector)

Arguments

mat	is a matrix and contains the values for different properties of different alternatives
weights	are the weights of each property in the decision making process
beneficial.vector	is a vector that contains the column number of beneficial properties.

Value

a vector containing the utility degree related to each alternative, higher utility indicates better ranking.

Examples

mat <- matrix(c(75.5, 95, 770, 187, 179, 239, 237,
420, 91, 1365, 1120, 875, 1190, 200,
