The classification-based consensus in multi-attribute group decision-making

Journal of the Operational Research Society, 2019
In multi-attribute group decision-making problem (MAGDM), the existing consensus reaching process (CRP) is to obtain a consensus ranking of alternatives.

A HYBRID FUZZY APPROACH TO FUZZY MULTI-ATTRIBUTE GROUP DECISION-MAKING

International Journal of Information Technology & Decision Making, 2011
The paper investigates fuzzy multi-attribute group decision-making (FMAGDM) problems. The important weights of the attributes and the ratings of the alternatives with respect to each attribute provided by multiple decision-makers are described by the linguistic variables expressed in triangular fuzzy numbers or trapezoidal fuzzy numbers.

Consensus of expert opinions in multi-attribute group decision making

International Journal of Applied Decision Sciences, 2014
This paper suggests a new approach for consensus of expert opinions in multi-attribute group decision making (MAGDM) problems. In the proposed approach, different opinions of a group of experts with unequal importance are aggregated using a fuzzy average based on Buckley’s hypothesis test.

Research on grey multi-attribute risk group decision-making method

2007 IEEE International Conference on Grey Systems and Intelligent Services, 2007
The problem of grey multi-attribute group decision making under risk, in which the attributes are interval grey number and the attribute weights are unknown is studied. Based on the ideal matrix, relative subordinate degree method is presented. Combining thoughts and method of grey system theory with classical risk decision-making method, the attribute

Compromise ratio method for fuzzy multi-attribute group decision making

Applied Soft Computing, 2007
The aim of this paper is to develop a compromise ratio (CR) methodology for fuzzy multi-attribute group decision making (FMAGDM), which is an important part of decision support system. Owing to fuzziness being inherent in decision data and group decision making processes, the crisp values are inadequate to model real-life situations. In this paper, the

Multi-Attribute Group Decision Making Models under Intuitionistic Fuzzy Environment

Applied Mechanics and Materials, 2012
In order to solve the problem of multi-attribute group-decision making with the elements of evaluation matrix are intuitionistic fuzzy sets, this paper offers corresponding TOPSIS models based on the information entropy weights and examples to be verified. The examples show the feasibility and effectiveness of the proposed models.

A multi-attribute group decision-making method approaching to group ideal solution

2007 IEEE International Conference on Grey Systems and Intelligent Services, 2007
This paper extends the TOPSIS framework of multi-attribute individual decision-making to group decision-making situations by introducing the concepts of group positive-ideal and group negative-ideal solutions. In our method, a relative-closeness to the group positive-ideal solution is defined to determine the ranking order of all alternatives by ...

A new way of handling multi-attribute group decision making problems

Journal of Intelligent & Fuzzy Systems, 2020
A novel idea of linguistic interval-valued intuitionistic neutrosophic fuzzy numbers (LIVINFNs) and operational laws of the numbers are introduced in this paper. LIVINF TOPSIS method is developed and application of the developed TOPSIS method to a multi-attribute group decision making (MAGDM) problem in a LIVINF environment is discussed.

Implementation of mail filtering based on multi-attribute group decision making

2008 International Conference on Audio, Language and Image Processing, 2008
The judgment of spam usually has some uncertainties, so it is easy to be misjudged, which lead to great loss. Aiming at the situation of misjudgment to mail filter presently, a method of spam filtering based on multi-attribute group decision making is presented in this paper.
