An automatic ranking approach for multi-criteria group decision making under intuitionistic fuzzy environment
Fuzzy Optimization and Decision Making - Tập 14 Số 3 - Trang 311-334 - 2015
Shen, Feng, Xu, Jiuping, Xu, Zeshui
Multi-criteria group decision making (MCGDM) problems are complex issues often faced by decision makers. In the decision making process, to deal with fuzziness and hesitation, the decision criteria provided by decision makers may take the form of intuitionistic fuzzy numbers. In this paper, we propose an automatic ranking approach for MCGDM under an intuitionistic fuzzy environment. We first propo...... hiện toàn bộ
The bi-objective fuzzy c-means cluster analysis for TSK fuzzy system identification
Fuzzy Optimization and Decision Making - Tập 6 - Trang 51-61 - 2007
Ta-Wei Hung
For conventional fuzzy clustering-based approaches to fuzzy system identification, a fuzzy function is used for cluster formation and another fuzzy function is used for cluster validation to determine the number and location of the clusters which define IF parts of the rule base. However, the different fuzzy functions used for cluster formation and validation may not indicate the same best number ...... hiện toàn bộ
Fuzzy interaction regression for short term load forecasting
Fuzzy Optimization and Decision Making - Tập 13 - Trang 91-103 - 2013
Tao Hong, Pu Wang
Electric load forecasting is a fundamental business process and well-established analytical problem in the utility industry. Due to various characteristics of electricity demand series and the business needs, electric load forecasting is a classical textbook example and popular application field in the forecasting community. During the past 30 plus years, many statistical and artificial intelligen...... hiện toàn bộ

A framework of distributionally robust possibilistic optimization
Fuzzy Optimization and Decision Making - - Trang 1-26 - 2024
Romain Guillaume, Adam Kasperski, Paweł Zieliński
In this paper, an optimization problem with uncertain constraint coefficients is considered. Possibility theory is used to model the uncertainty. Namely, a joint possibility distribution in constraint coefficient realizations, called scenarios, is specified. This possibility distribution induces a necessity measure in a scenario set, which in turn describes an ambiguity set of probability distribu...... hiện toàn bộ
No-arbitrage theorem for multi-factor uncertain stock model with floating interest rate
Fuzzy Optimization and Decision Making - Tập 16 - Trang 221-234 - 2016
Xiaoyu Ji, Hua Ke
In the stock models, the prices of the stocks are usually described via some differential equations. So far, uncertain stock model with constant interest rate has been proposed, and a sufficient and necessary condition for it being no-arbitrage has also been derived. This paper considers the multiple risks in the interest rate market and stock market, and proposes a multi-factor uncertain stock mo...... hiện toàn bộ
A single-variable method for solving min–max programming problem with addition-min fuzzy relational inequalities
Fuzzy Optimization and Decision Making - Tập 18 - Trang 433-449 - 2019
Ya-Ling Chiu, Sy-Ming Guu, Jiajun Yu, Yan-Kuen Wu
In this paper, we study the min–max programming problem with n addition-min fuzzy relational inequality constraints. We prove that when the problem is feasible, an optimal solution always exists with all variables being of the same value. Based on this result, the min–max programming problem can be simplified as a single-variable optimization problem with the same optimal objective value. To solve...... hiện toàn bộ
Consensus building with a group of decision makers under the hesitant probabilistic fuzzy environment
Fuzzy Optimization and Decision Making - Tập 16 - Trang 481-503 - 2016
Zeshui Xu, Wei Zhou
As a generalized fuzzy number, the hesitant fuzzy element (HFE) has been receiving increased attention and has recently become a popular topic. However, we find that the occurring probabilities of the possible values in the HFE are equal, which is obviously impractical. Consequently, in this paper, we propose a hesitant fuzzy number with probabilities, called the hesitant probabilistic fuzzy numbe...... hiện toàn bộ
Two storage inventory model in a mixed environment
Fuzzy Optimization and Decision Making - Tập 6 - Trang 391-426 - 2007
Manas Kumar Maiti, Manoranjan Maiti
Multi-item inventory models with two storage facility and bulk release pattern are developed with linearly time dependent demand in a finite time horizon under crisp, stochastic and fuzzy-stochastic environments. Here different inventory parameters—holding costs, ordering costs, purchase costs, etc.—are assumed as probabilistic or fuzzy in nature. In particular cases stochastic and crisp models ar...... hiện toàn bộ
Fuzzy Relation Equations for Compression/Decompression Processes of Colour Images in the RGB and YUV Colour Spaces
Fuzzy Optimization and Decision Making - Tập 4 - Trang 235-246 - 2005
H. Nobuhara, K. Hirota, F. Di. Martino, W. Pedrycz, S. Sessa
We use particular fuzzy relation equations for compression/decompression of colour images in the RGB and YUV spaces, by comparing the results of the reconstructed images obtained in both cases. Our tests are made over well known images of 256×256 pixels (8 bits per pixel in each band) extracted from Corel Gallery. After the decomposition of each image in the three bands of the RGB and YUV colour s...... hiện toàn bộ
