apply.WINGS: Apply WINGS (Weighted Influence Non-linear Gauge System)

In RMCDA: Multi-Criteria Decision Analysis

Apply WINGS (Weighted Influence Non-linear Gauge System)

Description

This function implements the core calculations of the WINGS method, ignoring any plotting or quadrant labeling. It returns three vectors:

• r_plus_c: (R + C) for each row/column

• r_minus_c: (R - C) for each row/column

• weights: normalized weights derived from (R + C).

Usage

apply.WINGS(mat)

Arguments

mat	A square numeric matrix. The WINGS method is typically applied on an n x n cross-impact or adjacency matrix.

Value

A list with three elements: r_plus_c, r_minus_c, and weights.

Examples

mat <- matrix(c(75.5, 95, 770, 187, 179, 239, 237,
420, 91, 1365, 1120, 875, 1190, 200,
74.2, 70, 189, 210, 112, 217, 112,
2.8, 2.68, 7.9, 7.9, 4.43, 8.51, 8.53,
21.4, 22.1, 16.9, 14.4, 9.4, 11.5, 19.9,

0.16, 0.16, 0.08, 0.08, 0.09, 0.07, 0.06), nrow=7)

colnames(mat)<-c("Toughness Index",	"Yield Strength",	"Young's Modulus",

result <- apply.WINGS(mat)
result$r_plus_c    # (R + C)
result$r_minus_c   # (R - C)
result$weights     # Weights
