MCDM (version 1.2)

RIM: Implementation of RIM Method for Multi-Criteria Decision Making Problems.

Description

The RIM function implements the Reference Ideal Method (RIM).

Usage

RIM(decision, weights, AB, CD)

Arguments

decision

The decision matrix (m x n) with the values of the m alternatives, for the n criteria.

weights

A vector of length n, containing the weights for the criteria. The sum of the weights has to be 1.

AB

A matrix (2 x n). AB[1,] corresponds with the A extrem, and AB[2,] represents the B extrem of the domain of each criterion.

CD

A matrix (2 x n). CD[1,] corresponds with the C extrem, and CD[2,] represents the D extrem of the ideal reference of each criterion.

Value

RIM returns a data frame which contains the score of the R index and the ranking of the alternatives.
