We present the generalized hybrid averaging (GHA) operator. It is a new aggregation operator that generalizes the hybrid averaging (HA) operator by using the generalized mean. Thus, we are able to generalize a wide range of mean operators such as the HA, the hybrid geometric averaging (HGA), the...

Una gran parte de las empresas de todo el mundo, y especialmente las PYMES occidentales, están perdiendo mucho dinero, y como consecuencia de ello gran parte de su competitividad potencial, debido a que los costes totales de calidad en que incurren, son inaceptablemente elevados. En la mayoría...

We develop a new approach for decision making in educational management based on the use of distance measures. We focus on the selection of a studies plan from the perspective of an academic institution. We try to develop this approach showing the benefits of establishing an ideal plan that we...

In any business sphere in which uncertainty is present use can be made of the theory of fuzzy sub-sets, expertons, algebra with intervals, etc. In this article we will be showing an application in uncertainty of Markov chains. As pointed out by Kaufmann and Gil Aluja, it is not strictly correct...

Los objetivos básicos de este artículo son presentar el actual Sistema Financiero de Angola tanto desde el punto de vista Institucional como de la Política Monetaria; realizar un análisis interno y externo del entorno competitivo del sistema financiero angoleño aplicando la Matriz DAFO o...

Average price is a numerical value that represents a set of prices, which may relate to firms, countries, or regions. This study presents new methods of average price aggregation that build on the unified aggregation operator (UAO). The UAO combines a wide range of sub-aggregation processes into...

Expertons and uncertain aggregation operators are tools for dealing with imprecise information that can be assessed with interval numbers. This paper introduces the uncertain generalized probabilistic weighted averaging (UGPWA) operator. It is an aggregation operator that unifies the probability...

The induced ordered weighted averaging distance (IOWAD) approach is very suitable in situations in which the available information is represented with exact numerical values. In this paper, we develop some extended IOWAD operators: the linguistic induced ordered weighted averaging distance...

Distortion risk measures summarize the risk of a loss distribution by means of a single value. In fuzzy systems, the Ordered Weighted Averaging (OWA) and Weighted Ordered Weighted Averaging (WOWA) operators are used to aggregate a large number of fuzzy rules into a single value. We show that...

El valor del consumidor ha sido un concepto muy estudiado desde hace tiempo por investigadores en las áreas de marketing. La mayoría de estas investigaciones están basadas en supuestos deterministas o aleatorios, al medir magnitudes o eventos que intervienen en el cálculo del valor del...
