ci_owa {Compind}

Ordered Weighted Average (OWA)

Description

The Ordered Weighted Averaging (OWA) operator is a multi-criteria decision aggregation method that is structurally non-compensatory (Yager, 1988).

Usage

ci_owa(x, id, indic_col, atleastjp)

Arguments

x

A data.frame containing score of the simple indicators.

id

Units' unique identifier.

indic_col

Simple indicators column number.

atleastjp

Fuzzy linguistic quantifier "At least j".

Value

An object of class "CI". This is a list containing the following elements:

CI_OWA_n

Composite indicator estimated values for OWA-.

CI_OWA_p

Composite indicator estimated values for OWA+.

wp

OWA weights' vector "More than j".

wn

OWA weights' vector "At least j".

ci_method

Method used; for this function ci_method="owa".
