This paper presents a new fuzzy group decision-making approach by using probabilities and ordered weighted averages (OWA). Thus, we are able to assess the problem considering probabilistic information and the attitudinal character of the decision maker. For doing so, the fuzzy generalized probabilistic OWA (FGPOWA) operator is presented. It is an aggregation operator that unifies the probabilit...

The basic assumption in data envelopment analysis patterns (DEA) (such as the CCR andBCC models) is that the value of data related to the inputs and outputs is a precise andpositive number, but most of the time in real conditions of business, determining precisenumerical value is not possible in for some inputs or outputs. For this purpose, differentmodels have been proposed in DEA for imprecis...

The conventional data envelopment analysis (DEA) measures the relative efficiencies of a set of decision making units (DMUs) with exact value of inputs and outputs. For imprecise data, i.e., mixtures of interval data and ordinal data, some methods have been developed to calculate the interval of the efficiency scores. This paper constructs a procedure to measure the efficiencies of DMUs with mi...

Hidden Markov models are popular tools for gesture recognition. Once the generative processes of gestures have been identified, an observation sequence is usually classified as the gesture having the highest likelihood, thus ignoring possible prior information. In this paper, we consider two potential improvements of such methods: the inclusion of prior information, and the possibility of consi...

In this paper, we propose a model to represent not completely deened data. These data are structured in rooted trees that take into account unknown and impossible values. We make a Galois connexion between entities described with imprecise data and their associated predicates. We propose an algorithm to nd concepts deened by a Galois connexion.

A complete survey of the published data reveals that the pattern of results (“successes” and “failures”) of attempted replications and variations of Wynn (1992) is neither as positive and robust nor as well tested as Wynn (2000) claims. The findings are inconsistent within and across studies using Wynn’s original addition and subtraction conditions as well as those using similar procedures but ...

The repercussions of and the reactions to Islamic organizations such as ISIS, Houthis, and Al-Qaeda, make it imperative for the leaders to redirect their investment compass in a proper way. This is especially true when considering whether to strengthen bilateral economic relations among nations, as critical decisions are influenced by certain variables that are based on heterogeneous and vague ...
