Cubic-VIKOR — Cubic extension of VIKOR
CUBIC-VIKOR (Cubic-VIKOR — Cubic extension of VIKOR) is a ranking multi-criteria decision-making (MCDM) method introduced by Jun, Y. B. Kim, C. S. Yang, K. O. in 2012. 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
cubic-vikor extends VIKOR to handle Cubic uncertainty. All arithmetic operations (normalisation, weighting, distance computation) are performed using Cubic Fuzzy Set (CuFS: interval [a,b] for internal membership, scalar λ for external) algebra. The final scores are defuzzified via P-order: (a⁻+a⁺)/2 and λ combined 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.
