Preference–approval structure combines the preference information of both ranking and approval, which extends ordinal model by incorporating two categories choice alternatives, that is, acceptable (good) unacceptable (bad), in modeling process. In this study, we present some axioms imply existence a unique distance function preference–approval structures. Based on theoretical analysis simulatio...

Many aggregation operators like fuzzy integrals and similar require a preference relation as input. If the number of decision alternatives increases it becomes almost impossible to provide the exponentially increasing number of preference statements which are needed because a preference relation is defined upon the power set of the set of decision alternatives. If, as in many real world applica...

With the beginning of the new millenium, the concept of group interactions in communication systems was boosted by the emergence of Web 2.0 technologies. Based on this new area of application, the notion of group decisions and group preferences also evolved, leading to new requirements for corresponding modeling frameworks. Purely numeric approaches are barely able to meet these newly emerging ...

Deep personalization of database queries requires a semantically rich, easy to handle and flexible preference model. Building on preferences as strict partial orders we provide a variety of intuitive and customizable base preference constructors for numerical and categorical data. For complex constructors we introduce the notion of ‘substitutable values’ (SV-semantics). Preferences with SV-sema...

Since the concept of linguistic variables was proposed, various kinds of linguistic terms have been used to express decision makers’ preference information in order to solve group decision making (GDM) problems. Probabilistic linguistic term set (PLTS) is a novel extension form of the existing linguistic variables. Based on it, the probabilistic linguistic preference relation (PLPR) has been pr...

Inspired by the concept of deviation measure between two linguistic preference relations, this paper further defines the deviation measure of a linguistic preference relation to the set of consistent linguistic preference relations. Based on this, we present a consistency index of linguistic preference relations and develop a consistency measure method for linguistic preference relations. This ...

The purpose of this study is to propose a model that explains the consumers’ perception of customization in e-commerce. This study suggests two determinants of consumer attitude toward the e-commerce website with customization options: perceived participation and perceived company responsiveness. Consumer attitude was posited to influence consumers’ intention to consider a long-term relationshi...
