Combining Heterogeneous Information in Group Decision Making
نویسنده
چکیده
Decision processes for solving group decision making problems are composed of two phases: (i) aggregation and, (ii) exploitation. When experts that participate in the group decision making process are not able to express their opinions using a same expression domain, then the use of information assessed in different domains, i.e., heterogeneous information, is necessary. In these cases, the information can be assessed in domains with different nature as linguistic, numerical and interval-valued. The aim of this contribution is to present an aggregation process to manage heterogeneous information contexts in the case of linguistic, numerical and interval-valued information. To do this, we take as representation base the 2-tuple fuzzy linguistic representation model [5].

متن کاملINTUITIONISTIC FUZZY DIMENSIONAL ANALYSIS FOR MULTI-CRITERIA DECISION MAKING
Dimensional analysis, for multi-criteria decision making, is a mathematical method that includes diverse heterogeneous criteria into a single dimensionless index. Dimensional Analysis, in its current definition, presents the drawback to manipulate fuzzy information commonly presented in a multi-criteria decision making problem. To overcome such limitation, we propose two dimensional analysis ba...
متن کاملMultiple attribute group decision making with linguistic variables and complete unknown weight information
Interval type-2 fuzzy sets, each of which is characterized by the footprint of uncertainty, are a very useful means to depict the linguistic information in the process of decision making. In this article, we investigate the group decision making problems in which all the linguistic information provided by the decision makers is expressed as interval type-2 fuzzy decision matrices where each of ...

In Group Decision Making is difficult that all experts have the same knowledge over the problem. In this contribution we shall focus in Group Decision Making problems in which the experts can express their knowledge over the alternatives using different types of information that will be called Heterogeneous Information. The aim of this contribution is to develop an aggregation process able to m...
متن کاملA NEW MULTIPLE CRITERIA DECISION-MAKING METHOD BASED ON BIPOLAR FUZZY SOFT GRAPHS
In this research study, we present a novel frame work for handling bipolar fuzzy soft information by combining bipolar fuzzy soft sets with graphs. We introduce several basic notions concerning bipolar fuzzy soft graphs and investigate some related properties. We also consider the application of the bipolar fuzzy soft graphs. In particular, three efficient algorithms are developed to solve mult...
