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.

Multi-attribute group decision making method based on evidence theory

2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017
Aiming at the group decision making problem of multi-person and multi-decision matrix, a multi-attribute group decision making method based on evidence theory has been proposed. In this method, firstly, the expert is regard as source of evidence to construct mass function of scheme, use expert weight coefficient to weight evidence, and to get the group

An affective cognition based approach to multi-attribute group decision making

Journal of Intelligent & Fuzzy Systems, 2018
Traditional multi-attribute group decision-making(MAGDM) methods are concerned with gathering group experts’ judgment preferences rather than providing insight from the affective cognitive perspective, which has difficulty dealing with group decision making problems with new input alternatives or large data samples automatically.

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

A Generalized Multi-Attribute Group Decision Making with Intuitionistic Fuzzy Set

2013
The aim of this paper is to introduce a new decision making model called the generalized multi-attribute group decision making (GMAGDM), which provides a very general form that includes multi-attribute decision making (MADM) and multi-attribute group decision making (MAGDM) as two special cases.

Study on the Problem of Assessment Level of Experts in Multi-attribute Group Decision Making

2009 Fifth International Conference on Natural Computation, 2009
This paper gives a new analytical solution for assessment level of experts in multi-attribute group decision-making. A new consistent estimator is made by the method on basis of mathematical statistic theory, according to experts’ information provided in decision-making matrices , assessment level of experts is estimated and judged adversely, that is ...

Fractional programming methodology for multi-attribute group decision-making using IFS

Applied Soft Computing, 2009
Owing to more vague concepts frequently represented in decision data, mathematical objects introduced by K.T. Atanassov and studied under the name ''intuitionistic fuzzy set'' (IFS) are more flexibly used to model real-life decision situations. The aim of this paper is to develop a new methodology for solving multi-attribute group decision-making ...

An interactive method for dynamic intuitionistic fuzzy multi-attribute group decision making

Expert Systems with Applications, 2011
This paper investigates the dynamic intuitionistic fuzzy multi-attribute group decision making (DIF-MAGDM) problems, in which all the attribute values provided by multiple decision makers (DMs) at different periods take the form of intuitionistic fuzzy numbers (IFNs), and develops an interactive method to solve the DIF-MAGDM problems.

Multi-attribute Group Decision Making-Based Decentralized Web Service Selection

2010 International Conference on Service Sciences, 2010
In ubiquitous network environment, network and resources change frequently, the capabilities of devices are quite different. All these features lead to local characteristics of QoS (quality of service). In addition, the centralized service registry and service selection methods cannot adapt to ubiquitous network environment.

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 ...
