FDOSM (Fuzzy Decision by Opinion Score Method) is a ranking multi-criteria decision-making (MCDM) method introduced by Mohammed, K. I. Zaidan, A. A. Zaidan, B. B. Albahri, O. S. Albahri, A. S. Alsalem, M. A. in 2019. 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

FDOSM is well-suited for group decision making with qualitative criteria. Fuzzy aggregation reduces individual bias.

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
  • Results depend on the chosen normalisation, weights, and parameter settings.
