According to the great mathematician Henri Lebesgue, making direct comparisons of objects with regard to a property is a fundamental mathematical process for deriving measurements. Measuring objects by using a known scale first then comparing the measurements works well for properties for which scales of measurement exist. The theme of this paper is that direct comparisons are necessary to establish measurements for intangible properties that have no scales of measurement. In that case the… Expand

Theoretical estimation of the probability of weight rank reversal in pairwise comparisons

- Mathematics, Computer Science
- Eur. J. Oper. Res.

Towards quantification of incompleteness in the pairwise comparisons method

- Computer Science, Mathematics
- Int. J. Approx. Reason.
- 2019

Four incompleteness indices have been developed, simple to calculate, each of them take into account both: the total number of missing data and their distribution in the PC matrix and it is demonstrated that both incomple completeness and inconsistency of data equally contribute to the sensitivity of the PC Matrix.
