Fuzzy decision making and consensus: Challenges
Group decision making is part of every organizational life. It is a type of participatory process in which multiple decision makers acting collectively, analyze problems, consider and evaluate several alternatives, and select from among the alternatives a solution. In such a situation, an important issue is the level of agreement or consensus achieved among the group of decision makers before o...
متن کاملOn Consensus Measures in Fuzzy Group Decision Making
In group decision making problems, a natural question in the consensus process is how to measure the closeness among experts’ opinions in order to obtain the consensus level. To do so, different approaches have been proposed. For instance, several authors have introduced hard consensus measures varying between 0 (no consensus or partial consensus) and 1 (full consensus or complete agreement). H...
متن کاملSoft consensus model for the group fuzzy AHP decision making
The fuzzy analytic hierarchy process (AHP) is an extension to the classical AHP that enables dealing with the impreciseness and vagueness of judgments. It has been frequently used for handling complex decision making problems that demand a group rather than a single decision maker. Group decision making aggregates the judgments of individuals into a joint decision. Although consensus is the des...
متن کاملLinguistic Measures Based on Fuzzy Coincidence for Reaching Consensus in Group Decision Making Linguistic Measures Based on Fuzzy Coincidence for Reaching Consensus in Group Decision Making
Assuming a linguistic framework, a model for the consensus reaching problem in heterogeneous group decision making is proposed. This model contains two types of linguistic consensus measures: linguistic consensus degrees and linguistic proximities to guide the consensus reaching process. These measures evaluate the current consensus state in three levels of action: level of the pairs of alterna...
متن کاملConsensus Decision Making by Fish
Decisions reached through consensus are often more accurate, because they efficiently utilize the diverse information possessed by group members [1-3]. A trust in consensus decision making underlies many of our democratic political and judicial institutions [4], as well as the design of web tools such as Google, Wikipedia, and prediction markets [5, 6]. In theory, consensus for the option favor...
