Enlargement of paired-comparison matrix’s consistency index in decision support systems

Paired comparisons are well known and are widely used in different scientific and technical problems all over the world, it is easy to understand, but difficult to use it when the number of compared objects is big, that can lead to mistakes. Authors of this paper deal with method, that allows to find incorrect expert’s marks in paired-comparisons matrix and also calculate a needed values to make incorrect marks better for the enlarge of paired-comparisons matrix consistency index.
