A Web Information System to Improve the Digital Library Service Quality
To asses the quality of the services provided by a digital library, traditional measures, such as the size of its collection, have usually been utilized. However, service quality also has to be evaluated by considering ...
A self-management mechanism for non-cooperative behaviors in large-scale group consensus reaching processes
(IEEE Xplore, 2018-03-21)
In large-scale group decision making (GDM), non-cooperative behavior in the consensus reaching process (CRP) is not unusual. For example, some individuals might form a small alliance with the aim to refuse attempts to ...
Comparing Two Approaches for Consensus Computation in Group Decision Making Problems
(IOS press, 2018-09)
In group decision making problems, the soft consensus calculus is an important topic. Soft consensus measures are utilized to show the different agreement degrees between decisors. Using the concept of coincidence we have ...
Dealing with Incomplete Information in Linguistic Group Decision Making by Means of Interval Type-2 Fuzzy Sets
Nowadays in the social network based decision making processes, as the ones involved in e-commerce and e-democracy, multiple users with di erent backgrounds may take part and diverse alternatives might be involved. This ...
Confidence based Consensus Model for Intuitionistic Fuzzy Preference relations
Intuitionistic fuzzy preference relation are gaining increasing relevance in the field of group decision making as they provide experts to allocate the uncertainty inherent in their proposed opinions. A key issue in this ...

Group decision-making based on heterogeneous preference relations with self-confidence
Preference relations are very useful to express decision makers’ preferences over alternatives in the process of group decision-making. However, the multiple self-confidence levels are not considered in existing preference ...
Strategic Weight Manipulation in Multiple Attribute Decision Making in an Incomplete Information Context
(IEEE Xplore, 2017-08-24)
In some real-world multiple attribute decision making (MADM) problems, a decision maker can strategically set attribute weights to obtain her/his desired ranking of alternatives, which is called the strategic weight ...
A Statistical Comparative Study of Different Similarity Measures of Consensus in Group Decision Making
An essential aim in group decision making (GDM) problems is to achieve a high level of consensus among experts. Consensus is defined as general or widespread agreement, and it is usually modelled mathematically via a ...
Confidence Based Consensus in Environments with High Uncertainty and Incomplete Information
(IOS Press, 2017)
With the incorporation of web 2.0 frameworks the complexity of decision making situations has exponentially increased, involving in many cases many experts, and a potentially huge number of different alternatives, leading ...
