Analysis of the reliability of the components of a multiservice communication network based on the theory of fuzzy sets
The article presents the results of modeling the solution to the problem of determining the reliability of the components of a multiservice communication network (MCN) based on the theory of fuzzy sets. The main characteristics of the equipment that affect the reliability parameters of the MCN are given. To solve the problem of determining the reliability of MCN components based on the theory of fuzzy sets, a multiservice network is presented in the form of a hierarchical diagram, which shows the main components of each network level. A multiservice network is presented as a parameter of the U function. The reliable state of the MCN depends on the state of the equipment at the corresponding levels. The results of modeling the solution to the problem of determining the reliability of MCN components based on the theory of fuzzy sets are presented using the mathematical apparatus of the theory of fuzzy sets and fuzzy logic in MATLAB fuzzy logic toolbox, fuzzyTECH
Fuzzy Transfer Pricing World: On the Analysis of Transfer Pricing with Fuzzy Logic Techniques
The arm’s length analysis of international transfer prices of multinational firms lacks sound methodological approach of the so-called function and risk analysis. In practice, such analyses are descriptive. Derived from Zadeh’s mathematical theory of fuzzy sets, this paper investigates a quantitative approach to identify the function and risk pattern of related parties of multinational companies. We illustrate our fuzzy logic approach with a simple case.
Integrated model of assessment competitive innovation products based on fuzzy sets theory
The article deals with integrated assessment model of innovation products. The basis of the model are four criteria. The coefficients of the weight of the criteria defined by the theory of fuzzy sets
Прийняття рішень за нечітко визначених умов
У статті розглянуто проблему прийняття рішень за нечітко визначених умов, що зумовлено наявністю у особи, що приймає рішення, (ОПР) як правило не тільки кількісної, а й якісної (некількісної) інформації. Запропоновано для вирішення цієї проблеми використання теорії нечітких множин у контексті теорії ігор. Запропоновано теоретико-ігрову модель прийняття рішення у сфері комерційного кредитування на підґрунті теорії нечітких множин.This article is devoted to the problem of decision-making in fuzzy certain conditions. It is offered for decision of this problem to use the theory of fuzzy sets in a context of the theory of games. The author suggests gametheoretical model of decision-making on the basis of the theory of fuzzy sets in commercial crediting

On Fuzzy Concepts
In this paper we try to combine two approaches. One is the theory of knowledge graphs in which concepts are represented by graphs. The other is the axiomatic theory of fuzzy sets (AFS).
The discussion will focus on the idea of fuzzy concept. It will be argued that the fuzziness of a concept in natural language is mainly due to the difference in interpretation that people give to a certain word. As different interpretations lead to different knowledge graphs, the notion of fuzzy concept should be describable in terms of sets of graphs. This leads to a natural introduction of membership values for elements of graphs. Using these membership values we apply AFS theory as well as an alternative approach to calculate fuzzy decision trees, that can be used to determine the most relevant elements of a concept
Fibered geometries
AbstractOur aim is to initiate the study of fibered geometries, in particular fibered projective planes and fibered generalized polygons. In fact, we apply the theory of fuzzy sets in a particular way on incidence geometry. Combinatorial and geometric questions arise. But also classical objects are recognized by this alternative view: for instance apartments arise naturally in the theory of “contagious values”
The use of Elements of Computational Intelligence in Problems of Forecasting of Corroding Constructions Durability
The modeling is considered of behavior of metal structures with changing geometric characteristics, which functioning in aggressive external environments. Information about the parameters of the external environment is incomplete or inaccurate. To formalize this information proposed to use the mathematical apparatus of the theory of fuzzy sets and interval analysis. The opportunities of the application of the ways have been examine
