In this paper, we study group decision-making problems based on intuitionistic preference relations. By measuring the uncertain information of intuitionistic preference relations and the average similarity degree of one individual intuitionistic preference relation to the others, we propose a...

Zbiory rozmyte okazaly sie bardzo pomocne w modelowaniu i efektywnym przetwarzaniu nieprecyzyjnych informacji. Czasem zachodzi jednak koniecznosc przyblizenia danego zbioru rozmytego za pomoca zbioru nierozmytego. W tym celu stosuje sie zazwyczaj defuzyfikacje (wyostrzanie), ale metoda ta...

We shall extend the notion of a K-proximity relation and its properties into an intuitionistic fuzzy sense. We generate an intuitionistic fuzzy K-proximity by a given fuzzy K-proximity in different forms. Also, intuitionistic fuzzy K-proximity mappings and its properties are considered.

This paper presents a method for defining a consistent market through the interpretation of different agents´ opinions. We suppose that every agent has his own opinion about the other agents being his possible competitors or not. These opinions are ex-ante defined and therefore (for a...

A special kind of lattice valued intui-tionistic fuzzy sets is introduced and investigated. Connections with all the previously introduced definitions are shown. Properties of cut subsets are deduced. Hesitancy margin for such fuzzy sets is also introduced. Conve-nience of new notions in...

Multiattribute decision making (MADM) with multiple formats of information, which is called heterogeneous MADM for short, is very complex and interesting in applications. The purpose of this paper is to extend the Linear Programming Technique for Multidimensional Analysis of Preference (LINMAP)...

To determine the weight vector and to aggregate the individual opinions are necessary steps in the classical methods for multi-criteria group decision-making problems in which the weight vectors of the decision makers and the criteria are incompletely known. In this paper, we propose a simple...

Typhoon is one of the major weather disasters in China’s coastal and some inland areas. This study focuses on the evaluation of typhoon disaster in Zhejiang province, China, based on intuitionistic fuzzy theory. First, some new intuitionistic fuzzy information aggregation operators are...

Tourism represents an important field of economic and social life in our country, and the main sector of the economy of Constanta County is the balneary touristic capitalization of Romanian seaside. In order to statistically analyze hydro tourism on Romanian seaside, we have applied...

This paper deals with the codispersion coefficient for spatial and temporal series. We present some results and simulations concerning the codispersion coefficient in the context of spatial models. The results obtained are immediate consequences of the asymptotic normality of the sample...
