sapevom: SAPEVO-M

In sapevom: Group Ordinal Method for Multiple Criteria Decision-Making

Description

Implements SAPEVO-M method

Usage

sapevom(criteriaEvaluations, alternativesEvaluations)

Arguments

criteriaEvaluations	a list of matrices with pairwise comparison of criteria, one matrix for each decisor.
alternativesEvaluations	a list of lists of matrices with pairwise comparison of alternatives, one list for each criterion containing one matrix for each decisor.

Details

Criteria and alternatives must be in the same order on all the matrices. Define row names for all matrices, like on documentation example, to have a more understandable output. The pairwise comparisons must be made with a scale of seven values, from -3 to 3, to represent the preferences.

Value

a vector with citeria weights and a dataframe with SAPEVO-M results.
