SAPEVO-M
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.
