This paper presents the induced generalized ordered weighted logarithmic aggregation (IGOWLA) operator, this operator is an extension of the generalized ordered weighted logarithmic aggregation (GOWLA) operator. It uses order-induced variables that modify the reordering process of the arguments included in the aggregation. The principal advantage of the introduced induced mechanism is the consideration of highly complex attitude from the decision makers. We study some families of the IGOWLA operator as measures for the characterization of the weighting vector. This paper presents the general formulation of the operator and some special cases, including the induced ordered weighted logarithmic geometric averaging (IOWLGA) operator and the induced ordered weighted logarithmic aggregation (IOWLA). Further generalizations using quasi-arithmetic mean are also proposed. Finally, an illustrative example of a group decision-making procedure using a multi-person analysis and the IGOWLA operator in the area of innovation management is analyzed.
Variance, as a measurement of dispersion, is a basic component of decision-making processes. Recent advances in intelligent systems have included the concept of variance in information fusion techniques for decision-making under uncertainty. These dispersion measures broaden the spectrum of decision makers by extending the toolset for the analysis and modeling of problems. This paper introduces some variance logarithmic averaging operators, including the variance generalized ordered weighted averaging (Var-GOWLA) operator and the induced variance generalized ordered weighted averaging (Var-IGOWLA) operator. Moreover, this paper analyzes some properties, families and particular cases of the proposed operators. Finally, an illustrative example of the characteristic design of the operators is proposed using real-world information retrieved from financial markets. The objective of this paper is to analyze the performance of some equities based on the expected payoff and the dispersion of its elements. Results show that the equity payoff results present diverse rankings combined with the proposed operators, and the introduced variance measures aid decision-making by offering new tools for information analysis. These results are particularly interesting when selecting logarithmic averaging operators for decision-making processes. The approach presented in this paper extends the available tools for decision-making under ignorance, uncertainty, and subjective environments.
El presente artículo trata el tema del turismo, de manera particular se centra en el Programa Pueblos Mágicos, programa turístico federal que surgió en México en el 2001. El objetivo del trabajo es evaluar la innovación del Programa Pueblos Mágicos, por lo que se ha decidido tomar los catorce indicadores con los que se valoran y seleccionan a los ganadores del concurso Proyecto Experiencias en Innovación Social desarrollado por la Comisión Económica para América Latina y el Caribe (CEPAL) junto con la Fundación W. K. Kellogg. En términos metodológicos el trabajo es mixto, cualitativo debido a que se apoya en el análisis de investigaciones previamente realizadas sobre turismo y los Pueblos Mágicos; y cuantitativo porque procesa, analiza y presenta datos tomados de la Secretaría de Turismo (SECTUR) y del Instituto Nacional de Estadística y Geografía (INEGI), en ambos casos la información se confronta con los indicadores y se asigna una valoración.
Los resultados muestran que en el Programa Pueblos Mágicos existen varias áreas de oportunidad en los rubros económico, social y ambiental. Finalmente se hacen algunas recomendaciones que versan sobre reconocer que el sector turístico es un fenómeno dinámico y complejo que está eslabonado con otros sectores y subsectores, por lo tanto, resulta necesario que sus indicadores también se encuentren interconectados y tengan la posibilidad de ser fácilmente valorados. Esto debido a que uno de los hallazgos del presente trabajo es la inexistencia de indicadores específicos para poder valorar y en su caso redirigir las estrategias del programa en pro de los distintos sectores participantes.
