Decision-making approach based on Pythagorean Dombi fuzzy soft graphs
Granular 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
Fuzzy time series forecasting based on hesitant fuzzy sets, particle swarm optimization and support vector machine-based hybrid method
Granular Computing - Tập 7 - Trang 861-879 - 2021
Manish Pant, Sanjay Kumar
In this paper, we propose hesitant fuzzy sets-based hybrid time series forecasting method using particle swarm optimization and support vector machine. Length of unequal intervals, weights of intervals and process of defuzzification are major factors that affect the forecasting accuracy of hesitant fuzzy sets-based time series models. The proposed hybrid fuzzy time series forecasting method uses h... hiện toàn bộ

Algebraic approaches to granular computing
Granular 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 sets
Granular 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 enterprises
Granular 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
An efficient spherical fuzzy MEREC–CoCoSo approach based on novel score function and aggregation operators for group decision making
Granular Computing - Tập 8 - Trang 1481-1503 - 2023
Guorou Wan, Yuan Rong, Harish Garg
The major objective of the current investigation is to build an integrated multiple criteria group decision-making (MCGDM) methodology based on combined compromise solution (CoCoSo) and spherical fuzzy set for determining the optimal solar power station. To begin with, an innovative spherical fuzzy score function is brought forward to strengthen the efficiency of the comparison for spherical fuzzy... hiện toàn bộ
An analytical study of Pythagorean fuzzy fractional wave equation using multivariate Pythagorean fuzzy fourier transform under generalized Hukuhara Caputo fractional differentiability
Granular Computing - Tập 9 - Trang 1-29 - 2024
Muhammad Akram, Muhammad Yousuf, Tofigh Allahviranloo
Pythagorean fuzzy fractional calculus provides a strong framework for modeling and analyzing complicated systems with uncertainty and indeterminacy. The primary focus of this article is to investigate the analytical solution of the Pythagorean fuzzy fractional wave equation using multivariate Pythagorean fuzzy Fourier transform under generalized Hukuhara Caputo fractional differentiability. To thi... hiện toàn bộ
Picture fuzzy soft $$\sigma$$ -algebra and picture fuzzy soft measure and their applications to multi-criteria decision-making
Granular Computing - Tập 8 - Trang 397-410 - 2022
Khalid Naeem, Samet Memiş
The concept of picture fuzzy soft sets (PFSSs) has been introduced as an efficacious extension of intuitionistic fuzzy soft sets to model uncertain information, especially when dealing with the responses “Yes”, “No”, and “Abstain”. Recently, Memiş [Another View on Picture Fuzzy Soft Sets and Their Product Operations with Soft Decision-Making. J New Theory 38(2022):1–13, 2022] has redefined the PFS... hiện toàn bộ
Interval-valued q-rung orthopair fuzzy interactive Dubois–Prade operator and its application in group decision-making
Granular Computing - Tập 8 - Trang 1799-1818 - 2023
Yunzhi Peng
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
