An attitudinal consensus degree to control feedback mechanism in group decision making with different adjustment cost
Wu, Jian; Sun, Qi; Fujita, Hamido; Chiclana, Francisco (Article)This article aims to study the influence of the group attitude on the consensus reaching process in group decision making (GDM). To do that, the attitudinal consensus index (ACI) is defined to aggregate individual consensus ... -
An attitudinal trust recommendation mechanism to balance consensus and harmony in group decision making
Wu, Jian; Li, Xue; Chiclana, Francisco; Yager, Ronal R. (Article)This article puts forward a trust based framework for building a recommendation mechanism for consensus in group decision making with interval-valued intuitionistic fuzzy information. To do that, it first presents an ... -
Consensus in Group Decision Making and Social Networks
Herrera-Viedma, Enrique; Cabrerizo, Francisco Javier; Chiclana, Francisco; Wu, Jian; Cobo, Manuel Jesus; Konstantin, Samuylov (Article)The consensus reaching process is the most important step in a group decision making scenario. This step is most frequently identified as a process consisting of some discussion rounds in which several decision makers, ... -
Consistency based estimation of fuzzy linguistic preferences. The case of reciprocal intuitionistic fuzzy preference relations
Chiclana, Francisco; Herrera-Viedma, Enrique; Wu, Jian (Conference)The decision-making assumption of all experts being able to express their preferences on all available alternatives of a decision-making problem might be considered unrealistic. This is specially true when the number of ... -
Dealing with Incomplete Information in Linguistic Group Decision Making by Means of Interval Type-2 Fuzzy Sets
Urena, Raquel; Kou, Gang; Wu, Jian; Chiclana, Francisco; Herrera-Viedma, Enrique (Article)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 ... -
An interaction consensus in group decision making under distributed trust information
Lifang Dai; Wu, Jian; Chiclana, Francisco; Fujita, Hamido; Herrera-Viedma, Enrique (Conference)A theoretical interaction consensus model in group decision making with distributed linguistic trust information is proposed. To do that, the concept of distributed linguists trust function (DLTF) is defined, and then the ... -
Isomorphic multiplicative transitivity for intuitionistic and interval-valued fuzzy preference relations and its application in deriving their priority vectors
Chiclana, Francisco; Wu, Jian; Liao, Huchang (Article)Intuitionistic fuzzy preference relations (IFPRs) are used to deal with hesitation while interval-valued fuzzy preference relations (IVFPRs) are for uncertainty in multi-criteria decision making (MCDM). This article aims ... -
A minimum adjustment cost feedback mechanism based consensus model for group decision making under social network with distributed linguistic trust
A theoretical feedback mechanism framework to model consensus in social network group decision making (SN-GDM) is proposed with following two main components: (1) the modelling of trust relationship with linguistic ... -
Multiplicative Consistency for Interval Valued Reciprocal Preference Relations
Wu, Jian; Chiclana, Francisco (Conference)The multiplicative consistency (MC) property of interval additive reciprocal preference relations (IARPRs) is explored, and then the consistency index is quantified by the multiplicative consistency estimated IARPR. The ... -
Multiplicative consistency of intuitionistic reciprocal preference relations and its application to missing values estimation and consensus building
Wu, Jian; Chiclana, Francisco (Article)The mathematical modelling and representation of Tanino's multiplicative transitivity property to the case of intuitionistic reciprocal preference relations (IRPRs) is derived via Zadeh's extension principle and the ... -
Non-dominance and Attitudinal Prioritisation Methods for Intuitionistic and Interval-Valued Intuitionistic Fuzzy Preference Relations
Wu, Jian; Chiclana, Francisco (Article)A novel intuitionistic fuzzy set (IFS) score function and an intuitionistic fuzzy preference relation (IFPR) quantifier guided non-dominance based prioritisation method are introduced. Based on Yager’s continuous OWA (COWA) ... -
A personalized feedback mechanism based on maximum harmony degree for consensus in group decision making
This article proposes a framework of personalized feedback mechanism to help multiple inconsistent experts to reach consensus in group decision making by allowing to select different feedback parameters according to ... -
A risk attitudinal ranking method for interval-valued intuitionistic fuzzy numbers based on novel attitudinal expected score and accuracy functions
Wu, Jian; Chiclana, Francisco (Article)This article investigates new score and accuracy functions for ranking interval-valued intuitionistic fuzzy numbers (IVIFNs). The novelty of these functions is that they allow the comparison of IVIFNs by taking into account ... -
A social network analysis trust-consensus based approach to group decision-making problems with interval-valued fuzzy reciprocal preference relations
Chiclana, Francisco; Wu, Jian (Article)A social network analysis (SNA) trust-consensus based group decision making model with intervalvalued fuzzy reciprocal preference relation (IFRPR) is investigated. The main novelty of this model is that it determines the ... -
Trust Based Consensus Model for Social Network in an Incomplete Linguistic Information Context
Chiclana, Francisco; Herrera-Viedma, Enrique; Wu, Jian (Article)A theoretical framework to consensus building within a networked social group is put forward. This article investigates a trust based estimation and aggregation methods as part of a visual consensus model for multiple ... -
A trust induced recommendation mechanism for reaching consensus in group decision making
Chiclana, Francisco; Liu, Yujia; Liang, Changyong; Wu, Jian (Article)This article addresses the inconsistency problem in group decision making caused by disparate opinions of multiple experts. To do so, a trust induced recommendation mechanism is investigated to generate personalised advices ... -
Uninorm trust propagation and aggregation methods for group decision making in social network with four tuples information
Wu, Jian; Chiclana, Francisco; Xiong, R. (Article)A novel social network based group decision making (SN-GDM) model with experts' weights not provided beforehand and with the following four tuple information: trust; distrust; hesitancy; and inconsistency, is introduced. ... -
Visual consensus feedback mechanism for group decision making with complementary linguistic preference relations
Chiclana, Francisco; Wu, Jian; Herrera-Viedma, Enrique (Book chapter)A visual consensus feedback mechanism for group decision making (GDM) problems with complementary linguistic preference relations is presented. Linguistic preferences are modelled using triangular fuzzy membership functions, ...
