Fuzzy WPM (Kahraman-Birgun-Yenen 2008) - Triangular Fuzzy Weighted Product
FUZZY-WPM (Fuzzy WPM (Kahraman-Birgun-Yenen 2008) - Triangular Fuzzy Weighted Product) is a ranking multi-criteria decision-making (MCDM) method introduced by Kahraman, C., Birgun, S., Yenen, V. Z. in 2008. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.
Key highlights
- Follows a transparent, reproducible computational procedure that can be audited step by step.
- Handles multiple criteria of differing scales and units within a single decision matrix.

When to use it
Fuzzy WPM applies the crisp WP formula componentwise on TFN (l, m, u) ratings and weights, then defuzzifies via centroid. Note this is multiplicative: unit-mismatched criteria can be compared without normalisation, but each rating must be strictly positive.
Strengths & limitations
- Follows a transparent, reproducible computational procedure that can be audited step by step.
- Handles multiple criteria of differing scales and units within a single decision matrix.
- Results depend on the chosen normalisation, weights, and parameter settings.
