OriginatorAkram, M., Shumaiza, Smarandache, F.Year2018Sources1

BN-TOPSIS (Bipolar Neutrosophic TOPSIS) is a topsis family multi-criteria decision-making (MCDM) method introduced by Akram, M., Shumaiza, Smarandache, F. in 2018. 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

BN-TOPSIS ranks alternatives in ascending order of the inferior ratio IR(i). The alternative with IR=0 (or minimum IR) is the best. The method uses a revised closeness degree instead of the classical TOPSIS coefficient to avoid division-by-zero when an alternative coincides with an ideal solution. BN-TOPSIS can handle bipolar information — each criterion is evaluated both positively (degree of satisfaction) and negatively (degree of dissatisfaction with respect to an implicit counter-property).

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
  • 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.
