We consider the problem of evaluating preferences for criteria used by university students when selecting a hotel accommodation during professional development program in foreign country. Input data analysis come from survey 202 respondents, who indicated their age, sex and whether they have previously visited The under evaluation are location, cost, typical guests, free breakfast, room ameniti...

We investigate an application of a mathematically robust minimization method - the gradient to consistencization problem pairwise comparisons (PC) matrix. Our approach sheds new light on notion priority vector and leads naturally definition instant vectors. describe sample family inconsistency indicators based various ways taking average value, which extends indicator “sup”- norm. apply this bo...

We describe a seriation algorithm for ranking a set of n items given pairwise comparisons between these items. Intuitively, the algorithm assigns similar rankings to items that compare similarly with all others. It does so by constructing a similarity matrix from pairwise comparisons, using seriation methods to reorder this matrix and construct a ranking. We first show that this spectral seriat...

This study investigates a powerful model, targeted to subjective assessments, based on pairwise comparisons. It provides a proof that a distance-based inconsistency reduction transforms an inconsistent pairwise comparisons (PC) matrix into a consistent PC matrix which is generated by the geometric means of rows of a given inconsistent PC matrix. The distance-based inconsistency indicator was de...

BACKGROUND In the last decade, network meta-analysis of randomized controlled trials has been introduced as an extension of pairwise meta-analysis. The advantage of network meta-analysis over standard pairwise meta-analysis is that it facilitates indirect comparisons of multiple interventions that have not been studied in a head-to-head fashion. Although assumptions underlying pairwise meta-ana...

A typical approach to handle the complexity of multi-faceted decision-making problems is to use multiattribute decision-making (MADM) methods based on pairwise comparisons. Fuzzy set theory has also been employed to cope with the uncertainty and vagueness involved in conducting the comparisons between components of a decision model. An important issue regarding the reliability of the output is ...

There is considerable interest in comparing functional genomic data across species. One goal of such work is to provide an integrated understanding of genome and phenotype evolution. Most comparative functional genomic studies have relied on multiple pairwise comparisons between species, an approach that does not incorporate information about the evolutionary relationships among species. The st...
