Decision-making approach based on Pythagorean Dombi fuzzy soft graphsGranular Computing - Tập 6 - Trang 671-689 - 2020
Muhammad Akram, Gulfam Shahzadi
A Pythagorean fuzzy set model is more useful than intuitionistic fuzzy set model to handle the imprecise information involving both membership and nonmembership degrees, and a soft set is an other parameterized point of view for handling the vagueness. A Pythagorean fuzzy soft graph is considered more capable than intuitionistic fuzzy soft graph for representing the parametric relationships betwee...... hiện toàn bộ
Algebraic approaches to granular computingGranular Computing - Tập 6 - Trang 119-131 - 2019
Hua Mao, Mengjun Hu, Yiyu Yao
We study the granular structures in granular computing from algebraic views. We model a granular structure based on an algebra that consists of a universe and a closure operator. Based on this formulation, we define the basic granules in a granular structure through the notion of subalgebras. Using formal concept analysis and rough set analysis as two examples, we demonstrate that the proposed for...... hiện toàn bộ
A novel high-order fuzzy time series forecasting method based on probabilistic fuzzy setsGranular Computing - Tập 4 - Trang 699-713 - 2019
Sanjay Kumar, Krishna Kumar Gupta
Recently, the probabilistic fuzzy set has been applied by the researchers in various domains to model the uncertainties in the system due to both fuzziness and randomness. In this research paper, we propose a novel high-order probabilistic fuzzy set-based forecasting method in the environment of both non-probabilistic and probabilistic uncertainties. We have also proposed a novel probability-based...... hiện toàn bộ
GIFIHIA operator and its application to the selection of cold chain logistics enterprisesGranular Computing - - 2017
Shanshan Meng, Nan Liu, Yingdong He
In this paper, we present some induced hybrid interaction averaging operators under intuitionistic fuzzy environments, including the induced hybrid interaction averaging operator and the generalized induced hybrid interaction averaging operator under intuitionistic fuzzy environments. The properties of these operators are investigated. The main advantages of these operators are that, (1) the inter...... hiện toàn bộ
Interval-valued q-rung orthopair fuzzy interactive Dubois–Prade operator and its application in group decision-makingGranular Computing - Tập 8 - Trang 1799-1818 - 2023

The Dubois–Prade operator can transform its parameter into different values when processing data, which can make it more flexible. Interval-valued q-rung orthopair fuzzy sets (IVq-ROFSs) give decision-makers more degrees of freedom. Combining the flexibility of the Dubois–Prade operators and the degrees of freedom of IVq-ROFSs, this paper proposes the interval-valued q-rung orthopair fuzzy Dubois–...... hiện toàn bộ
