Hesitant fuzzy geometric Bonferroni means

Multicriteria Pythagorean fuzzy decision analysis

We introduce the concepts of entropy and cross-entropy for hesitant fuzzy information, and discuss their desirable properties. Several measure formulas are further developed, and the relationships among the proposed entropy, cross-entropy, and similarity measures are analyzed, from which we can find that three measures are interchangeable under certain conditions. Then we develop two multiattribute decision-making methods in which the attribute values are given in the form of hesitant fuzzy sets reflecting humans' hesitant thinking comprehensively. In one method, the weight vector is determined by the hesitant fuzzy entropy measure, and the optimal alternative is obtained by comparing the hesitant fuzzy cross-entropies between the alternatives and the ideal solutions; in another method, the weight vector is derived from the maximizing deviation method and the optimal alternative is obtained by using the TOPSIS method. An actual example is provided to compare our methods with the existing ones. © 2012 Wiley Periodicals, Inc. © 2012 Wiley Periodicals, Inc.

Hesitant fuzzy entropy and cross-entropy and their use in multiattribute decision-making

This study investigates the group decision making under interval-valued intuitionistic fuzzy environment in which the attributes and experts are in different priority level. We first propose some interval-valued intuitionistic fuzzy aggregation operators such as the interval-valued intuitionistic fuzzy prioritized weighted average (IVIFPWA) operator, the interval-valued intuitionistic fuzzy prioritized weighted geometric (IVIFPWG) operator. These proposed operators can capture the prioritization phenomenon among the aggregated arguments. Then, some of their desirable properties are investigated in detail. Furthermore, an approach to multi-criteria group decision making based on the proposed operators is given under interval-valued intuitionistic fuzzy environment. Finally, a practical example about talent introduction is provided to illustrate the developed method.

Some information measures for interval-valued intuitionistic fuzzy sets

In many fields, how to catch the related-topic Web resources is crucial. As a vertical search method, focused crawler has received great attention in recent years. Currently, most focused crawlers consider multiple evaluating factors of the hyperlinks and use the weighted sum approach to compute the priorities of unvisited hyperlinks. However, the proper weighted coefficients are hard to determine, and their unsuitable values may even cause the direction of crawlers to deviate seriously from the topic. To overcome this issue, this article builds a multi-objective optimization model based on Web text and link structure and designs a crawler framework called the Web space evolution (WSE), where a hyperlink bank whose radius is gradually increased is introduced to extend the search scape of crawlers in Web space. To improve the uniformity and diversity of hyperlinks, a nearest and farthest candidate solution method is combined with the fast non-dominated sorting to choose Pareto-optimal solutions (hyperlinks). A domain ontology based on the formal concept analysis is applied to establish the topic model. By incorporating the WSE and the domain ontology into the focused crawling, a novel focused crawler called FCWSEO is proposed to collect topic-relevant webpages. The experimental results on the rainstorm disaster domain show that the FCWSEO outperforms other focused crawler strategies in terms of the quantity and quality of retrieved relevant webpages.

This paper handles the new information entropy measure and divergence measure associated with intuitionistic fuzzy variables (IFVs). Based on credibility distribution and credibility measure of intuitionistic fuzzy variable, the credibility entropy formulas of discrete and continuous IFVs are proposed and some of their properties are investigated. The cross-entropy of intuitionistic fuzzy variable and its relationship with credibility entropy are then discussed. Finally, some numerical examples are given to illustrate the practicability of the presented credibility entropy and cross-entropy of intuitionistic fuzzy variable. Also, we make some comparative analysis on the credibility cross-entropy measure and some existing distance measures of IFVs in the pattern recognition problem.
