In RMCDA: Multi-Criteria Decision Analysis

Apply Weighted Sum Model (WSM) or Weighted Product Model (WPM) on data

Description

Apply Weighted Sum Model (WSM) or Weighted Product Model (WPM) on data

Usage

apply.WSM_WPM(mat, beneficial.vector, weights, method = "WSM")

Arguments

mat	is a matrix and contains the values for different properties of different alternatives.
beneficial.vector	is a vector that contains the column number of beneficial properties.
weights	are the weights of each property in the decision making process
method	can either be 'WSM' or 'WPM', set to 'WSM' by default.

Value

a vector containing the calculated preference score, run rank(-apply.WSM(mat, beneficial.vector, weights)) to get the ranks.

Examples

mat <- matrix(c(250, 200, 300, 275,
 225, 16, 16, 32,
  32, 16, 12, 8,
   16, 8, 16, 5,
    3, 4, 4, 2), nrow=5, ncol=4)
colnames(mat)<-c("Price", "Storage space",
 "Camera", "Looks")
rownames(mat)<-paste0("Mobile ", seq(1, 5, 1))
beneficial.vector <- c(2, 3, 4)
weights <- c(0.25, 0.25, 0.25, 0.25)
apply.WSM_WPM(mat, beneficial.vector, weights, "WSM")
