LoPM — Limits on Property Method
LOPM (LoPM — Limits on Property Method) is a ranking multi-criteria decision-making (MCDM) method introduced by Farag, M. M. in 2020. 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
Higher m_i = better property satisfaction. Lower-limit: limit/x ≤ 1 if x meets or exceeds limit; upper-limit: x/limit ≤ 1 if x is at or below limit. Score = 1 when exactly at limit. Primarily designed for material selection problems.
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.
