RMDA provides a variety of Multi-Criteria Decision Analysis (MCDM) method. Below we review some of these methods and explain how you can utilize this R package for your specific data.
###Load the R package
###Let’s see how the input data looks like
data <- read.csv(system.file("extdata", "AHP_input_file.csv", package = "RMCDA"), header=FALSE)
mat.lst <- read.csv.AHP.matrices(data)
