With the incorporation of web 2.0 frameworks the complexity of decision making situations has exponentially increased, involving in many cases a huge number of decision makers, and many different alternatives. In the literature we can find a great variety of methodologies to assist multi-person decision making. However these classical approaches are not suitable to deal with such complexity sin...

Large-scale group decision-making (LS-GDM) problems are common in the daily life of human beings. Both information fusion and computing with words (CWW) technologies LS-GDM suffer from challenges. In current research, a proportional hesitant fuzzy linguistic term set (PHFLTS) will be applied to capture preferences sub-groups LS-GDM, which decreases lost processes. Novel semantic representation ...

This paper proposes a metaheuristic approach for Group Decision Making (GDM) model integrating heterogeneous information. Instead of converting information into single form, the proposed incorporates using Weighted Power Average (WPA) operator to prevent loss. The consensus degree between individual and group (decision matrix) is then determined on basis deviation degree. In addition, adjust de...

This work presents a new fuzzy multiple attributes decision-making (FMADM) approach, i.e., fuzzy simple additive weighting system (FSAWS), for solving facility location selection problems by using objective/subjective attributes under group decision-making (GDM) conditions. The proposed system integrates fuzzy set theory (FST), the factor rating system (FRS) and simple additive weighting (SAW) ...

Abstract Social networks (SNs) have become popular as a medium for disseminating information and connecting like-minded people. They play central role in decision-making by correlating the behaviors preferences of connected agents. However, it is difficult to identify social influence effects decision-making. In this article, we propose framework how describe uncertain nature network group (SN-...

Abstract In the past 10 years, a large number of consensus-reaching approaches for group decision making (GDM) have been proposed. While these methods either focus on cost consensus reaching or convergency process, efficiency has long ignored. Meanwhile, measurements threshold are often determined by some subjective and intuitive judgements, such as management experience estimations degree sati...

Hesitant fuzzy linguistic preference relation (HFLPR) is of interest because it provides an efficient way for opinion expression under uncertainty. For enhancing the theory group decision making (GDM) with HFLPR, paper introduces a method addressing GDM based on consistency and consensus measurements, which involves (1) defining hesitant geometric index (HFLGCI) proposing algorithm checking inc...

In the debate between marginal decision-making and full absorbance that has been going on since the nineteenth century, activity-based costing/management (ABC/M) appeared as a promising decision support tool which answers the criticism leveled against traditional cost accounting. This paper describes the strengths and weaknesses of ABC/M from a global value creation perspective, in an effort to...

The development of distribution linguistic provides a new research idea for information group decision-making (GDM) problems, which is more flexible and convenient experts to express their opinions. However, in the process using fuzzy preference relations (DLFPRs) solve GDM there are few studies that pay attention both internal consistency adjustment external consensus experts. Therefore, this ...
