This paper proposes a chi-square method (CSM) to obtain a priority vector for group 11 decision making (GDM) problems where decision-makers’(DMs’) assessment on alternative is 12 furnished as incomplete reciprocal preference relations with missing values. Relevant theorems 13 and iterative algorithm about CSM are proposed. Satty’s consistency ratio concept is adapted to 14 judge whether an inco...

In decision-making, information is usually provided by means of fuzzy preference relations. However, there may be cases in which experts do not have an in-depth knowledge of the problem to be solved, and thus their fuzzy preference relations may be incomplete, i.e. some values may not be given or may be missing. In this paper we present a procedure to find out the missing values of an incomplet...

Preference relations are at the heart of many fundamental concepts in artificial intelligence, ranging from utility comparisons, to defeat among strategies and relative plausibility states, just mention a few. Reasoning about such has been object extensive research wealth formalisms exist express reason them. One formalism is conditional logic, which focuses on reasoning “best” alternatives acc...

Intelligent Information systems do not usually possess complete information about the world with which they interact. The AGM paradigm has become one of the standard frameworks for modeling changes to repositories of information. Its principal constructions for change operators rely on some form of underlying preference relation. The process of changing such a preference relation is known as a ...

A general multiple attribute decision-making (MADM) approach is proposed to integrate subjective preferences and objective information and to assess the relative weights of attributes, where subjective preferences are expressed either by a fuzzy preference relation on decision alternatives or by a pairwise comparison matrix on the relative weights of attributes or by both of them and objective ...

There are several contexts of non-monotonic reasoning where a prior7 ity between rules is established whose purpose is preventing conflicts. 8 One formalism that has been widely employed for non-monotonic reasoning is 9 the sceptical one known as Defeasible Logic. In Defeasible Logic the tool used 10 for conflict resolution is a preference relation between rules, that establishes the 11 priorit...

In this paper, we study the logical semantics of actions, preference, and commitment. The semantics is based on the possible world models for dynamic logic of actions. A binary preference relation between possible worlds is associated with the model. Then the preference between actions are determined by comparing that of their consequences. While the preference will influence the agent’s choice...

The aim of this paper is to propose a procedure to estimate missing preference values when dealing with incomplete fuzzy linguistic preference relations assessed using a 2–tuple fuzzy linguistic approach. This procedure attempts to estimate the missing information in an individual incomplete fuzzy linguistic preference relation using only the preference values provided by the respective expert....

Abstract Background Theoretical models emphasize the importance of implicit self-related weight attitudes for maintenance body dissatisfaction. Even though dissatisfaction is increased in obesity, only general weight-related have been investigated so far. Therefore, present study assessed and their relation to food. Methods Women with overweight obesity (OW; n = 71) women normal (NW; 44) comple...

A choice assessment has been found to be a more accurate method of identifying preferences than is single-item presentation. However, it is not clear whether the effectiveness of reinforcement varies positively with the degree of preference (i.e., whether the relative preference based on the results of a choice assessment predicts relative reinforcer effectiveness). In the current study, we att...
