Range of Value method
ROV (Range of Value method) is a ranking multi-criteria decision-making (MCDM) method introduced by Yakowitz, D. S., Lane, L. J., Szidarovszky, F. in 1993. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
ū_i ∈ [0,1]. u⁺ and u⁻ represent optimistic (best weight assignment) and pessimistic (worst weight assignment) utilities. Their average ū provides a robust ranking that accounts for uncertainty in the exact ordering of criterion importance. ROV is particularly useful when the decision-maker knows the criterion weights but is uncertain about their exact values.
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.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
