Interval extension of MOORA
IV-MOORA (Interval extension of MOORA) is a ranking multi-criteria decision-making (MCDM) method introduced by Moore, R. E. in 1966. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
iv-moora extends MOORA to handle Interval uncertainty. All arithmetic operations (normalisation, weighting, distance computation) are performed using Interval Number (IN: [a, b]) algebra. The final scores are defuzzified via midpoint (a+b)/2 before ranking.
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.
- May exhibit rank reversal when alternatives are added to or removed from the set.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
