In this article we propose the use of intuitionistic fuzzy sets (Atanassov [2]) as a tool for reasoning under imperfect facts and imprecise knowledge, particularly via distances between intuitionistic fuzzy sets. We consider two issues: (1) a method to evaluate a degree (extent) of agreement (meant here as a distance from consensus) in a group of experts (individuals), and (2) a new approach to supporting medical diagnosis based on a reasoning scheme using a distance between intuitionistic fuzzy sets.

Opis:: This paper presents recent approaches in soft computing to manage imprecision and uncertainty which appear in software reliability engineering. Firstly, recent approaches like imprecise probabilities, generalized intervals, fuzzy sets and intuitionistic-fuzzy sets are shortly described, and the usage of intuitionistic fuzzy numbers for system reliability computation is shown. Intuitionistic-fuzzy approaches for software reliability growth models are proposed and experimental results are given.

Opis:: The article proposes application of artificial intelligence methods to assess students of technical universities. The level of achieved educational goals can be assessed using measurements based on the idea of Fuzzy Intuitionistic Sets (IFS). A classification algorithm was developed and an exemplary distribution of the criteria values using IFS was presented. The application of the proposed approach in online education can enrich the student evaluation process with additional information related to the uncertainty or lack of data.
W artykule proponuje się do oceny studenta uczelni technicznych użycie intuicjonistycznych zbiorów rozmytych, które znajdują zastosowanie w metodach sztucznej inteligencji. Poziom osiąganych celów edukacyjnych można ocenić za pomocą miar opartych na idei rozmytych zbiorów intuicjonistycznych (IFS). Opracowano algorytm klasyfikacji oraz zaprezentowano przykładowy rozkład wartości kryteriów z wykorzystaniem IFS. Zastosowanie proponowanego podejścia w kształceniu online może wzbogacić proces oceny studenta o dodatkowe informacje związane z niepewnością lub brakiem danych.

Opis:: In this paper we present some fuzzy modal operators and show their two possible applications. These operators are fuzzy generalizations of modal operators well-known in modal logics. We present an application of some compositions of these operators in approximations of fuzzy sets. In particular, it is shown how skills of candidates can be matched for selecting research projects. The underlying idea is based on the observation that fuzzy sets approximations can be viewed as intuitionistic fuzzy sets introduced by Atanassov. Distances between intuitionistic fuzzy sets, proposed by Szmidt and Kacprzyk, support the reasoning process. Also, we point out how modal operators are useful for representing linguistic hedges, that is terms like “very”, “definitely”, “rather”, or “more or less”.

Opis:: We discuss some aspects of similarity measures in the context of Atanassov’s intuitionistic fuzzy sets (IFSs, for short). IFSs, proposed in 1983, are a relatively new tool for the modeling and simulation and, because of their construction, present us with new challenges as far the similarity measures are concerned. Specifically, we claim that the distances alone are not a proper measure of similarity for the IFSs. We stress the role of a lack of knowledge concerning elements (options, decisions, etc.) and point out the role of the opposing (complementing) elements. We also pay attention to the fact that it is not justified to talk about similarity when one has not enough knowledge about the compared objects/elements. Some novel measures of similarity are presented.

Opis:: A generalization of technique for establishing order preference by similarity to the ideal solution (TOPSIS) in the intuitionistic fuzzy setting based on the redefinition of intuitionistic fuzzy sets theory (A−IFS) in the framework of Dempster-Shafer theory (DST) of evidence is proposed. The use of DST mathematical tools makes it possible to avoid a set of limitations and drawbacks revealed recently in the conventional Atanassov’s operational laws defined on intuitionistic fuzzy values, which may produce unacceptable results in the solution of multiple criteria decision-making problems. This boosts considerably the quality of aggregating operators used in the intuitionistic fuzzy TOPSIS method. It is pointed out that the conventional TOPSIS method may be naturally treated as a weighted sum of some modified local criteria. Because this aggregating approach does not always reflects well intentions of decision makers, two additional aggregating methods that cannot be defined in the framework of conventional A−IFS based on local criteria weights being intuitionistic fuzzy values, are introduced. Having in mind that different aggregating methods generally produce different alternative rankings to obtain the compromise ranking, the method for aggregating of aggregation modes has been applied. Some examples are used to illustrate the validity and features of the proposed approach.

Opis:: In this paper we present an application of fuzzy approximation operators in supporting medical diagnosis. These operators are compositions of fuzzy modal operators. The underlying idea is based on the observation that approximations of fuzzy sets may be viewed as intuitionistic fuzzy sets. Reasoning scheme is determined by distances between intuitionistic fuzzy sets proposed by Szmidt and Kacprzyk.

Opis:: In this article we show and justify how to calculate distances for intuitionistic fuzzy sets. We show a proper way of calculations not only from the point of view of mathematical properties but also the way enabling us to make use of all the relevant information we have. We also discuss incorrect approaches leading to Jumping to conclusions

This paper describes works in progress on the problem of classification of imbalanced and overlaping classes using intuitionistic fuzzy sets. A fuzzy set approach is presented first — the classes are recognized using a fuzzy classifier. Next, an intuitionistic fuzzy set representation is proposed. We show that intuitionistic fuzzy classifier has some natural tendency to deal efficiently with imbalanced and overlaping data. We also explore in details the evaluation of the classifier results (especially from the point of view of recognizing the smaller class).
