Combinatorial and Sampling Approaches to Determining the Priority Vector from an Incomplete Pairwise Comparison Matrix on the Set of Spanning Trees
Vitaliy Tsyganok, Oksana Mulesa
This paper considers combinatorial and sampling approaches to deriving a priority vector from an incomplete pairwise comparison matrix. It is shown that the informationally signifi…
From Open Source Intelligence to Decision Making: a Hybrid Approach
Vitaliy Tsyganok, Sergii Kadenko, Oleh Andriichuk
We provide an overview of tools enabling users to utilize data from open sources for decision-making support in weakly-structured subject domains. Presently, it is impossible to re…
Comparing Efficiency of Expert Data Aggregation Methods
Sergii Kadenko, Vitaliy Tsyganok
Expert estimation of objects takes place when there are no benchmark values of object weights, but these weights still have to be defined. That is why it is problematic to define t…
Usage of Decision Support Systems for Conflicts Modelling during Information Operations Recognition
Oleh Andriichuk, Vitaliy Tsyganok, Dmitry Lande +2
Application of decision support systems for conflict modeling in information operations recognition is presented. An information operation is considered as a complex weakly structu…
Information Operations Recognition: from Nonlinear Analysis to Decision-making
Aleksandr G. Dodonov, Dmitry V. Lande, Vitaliy V. Tsyganok +3
The book is dedicated to the issues of information operations recognition based on analysis of information space, particularly, web-resources, social networks, and blogs. In this c…
A Method with Feedback for Aggregation of Group Incomplete Pair-Wise Comparisons
Vitaliy Tsyganok, Sergii Kadenko, Oleh Andriichuk +1
A method for aggregation of expert estimates in small groups is proposed. The method is based on combinatorial approach to decomposition of pair-wise comparison matrices and to pro…
The (logarithmic) least squares optimality of the arithmetic (geometric) mean of weight vectors calculated from all spanning trees for incomplete additive (multiplicative) pairwise comparison matrices
Sándor Bozóki, Vitaliy Tsyganok
Complete and incomplete additive/multiplicative pairwise comparison matrices are applied in preference modelling, multi-attribute decision making and ranking. The equivalence of tw…
