The complexity of multi-criteria decision problems requires the involvement a group experts, who can contribute their knowledge, experience and opinions to decision-making process. aim this study is present new analytic hierarchy process (AHP) framework, called GSD-IJ. main idea emphasize satisfaction with final decision, which measured by index. GSD-IJ based on geometric mean standard deviatio...

In applications such as rank aggregation, mixture models for permutations are frequently used when the population exhibits heterogeneity. this work, we study widely Mallows model. high-dimensional setting, propose a polynomial-time algorithm that learns of on n elements with optimal sample complexity is proportional to logn, improving upon previous results scale polynomially n. high-noise regim...

Hesitant fuzzy linguistic preference relation (HFLPR) is of interest because it provides an efficient way for opinion expression under uncertainty. For enhancing the theory group decision making (GDM) with HFLPR, paper introduces a method addressing GDM based on consistency and consensus measurements, which involves (1) defining hesitant geometric index (HFLGCI) proposing algorithm checking inc...

In this paper, conservative simultaneous confidence intervals for multiple comparisons among mean vectors in multivariate normal distributions are considered. Some properties of the multivariate Tukey-Kramer type procedures for pairwise comparisons and for comparisons with a control are presented. The upper bounds for the conservativeness of the procedures are discussed. Finally, numerical resu...

Subjective quality assessment is considered a reliable method for quality assessment of distorted stimuli for several multimedia applications. The experimental methods can be broadly categorized into those that rate and rank stimuli. Although ranking directly provides an order of stimuli rather than a continuous measure of quality, the experimental data can be converted using scaling methods in...

In this paper we consider the collaborative ranking setting: a pool of users each provides a small number of pairwise preferences between d possible items; from these we need to predict each users preferences for items they have not yet seen. We do so by fitting a rank r score matrix to the pairwise data, and provide two main contributions: (a) we show that an algorithm based on convex optimiza...

The pairwise comparisonsmethod is a convenient tool used when the relative order among different concepts (alternatives) needs to be determined. One popular implementation of the method is based on solving an eigenvalue problem for the pairwise comparisons matrix. In such cases the ranking result the principal eigenvector of the pairwise comparisonmatrix is adopted, whilst the eigenvalue is use...

The biological characteristics of Aedes aegypti (Diptera, Culicidae), which is a vector of dengue and yellow fever, make this organism a good model for studying population structure and the events that may influence it under the effect of human activity. We assessed the genetic variability of five A. aegypti populations using RAPD-PCR technique and six primers. Four populations were from Brazil...
