FUZZY-SPOTIS (Fuzzy SPOTIS — Fuzzy extension of SPOTIS) is a ranking multi-criteria decision-making (MCDM) method introduced by Shekhovtsov, A., Paradowski, B., Więckowski, J., Kizielewicz, B., Sałabun, W. in 2022. 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-spotis extends SPOTIS to handle Fuzzy uncertainty. All arithmetic operations (normalisation, weighting, distance computation) are performed using Triangular Fuzzy Number (TFN: l, m, u) algebra. The final scores are defuzzified via centroid (l+m+u)/3 before ranking.

Strengths & limitations

Strengths
  • 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.
Limitations
  • Assumes full compensation — a strong score on one criterion can offset a weak score on another.
