El proceso de toma de decisiones tiene una incidencia relevante en los resultados de las empresas, lo que ha llevado a desarrollar novedosos métodos que permitan evaluar bajo condiciones no controlables elementos subjetivos y racionales. En ese sentido, el objetivo principal de este trabajo estudia los operadores de agregación en la toma de decisiones en entornos inciertos. Se presentan dos metodologías que permiten agregar información, que se llaman operadores OWA y BON-OWA. La aplicación de estos operadores se realiza en la selección de lanzamiento de nuevos productos. La principal ventaja de estos operadores es que permiten capturar la actitud del decisor y la comparación e interrelación continua de la información. Así, se destaca el análisis holístico que ofrecen estos métodos sobre la toma de decisiones en incertidumbre, que permite integrar conceptos de la teoría administrativa y la teoría de la agregación en un caso aplicado, visualizando como la inclusión de la información genera cambios dentro de los rankings de selección de alternativas. || Decision-making has a relevant incidence on firms results, which has led to develop novel methods that allow assessing subjective and rational elements under uncontrollable conditions. In this sense, the main aim of this work is to study aggregation operators in decision-making in uncertain environments. Two methodologies allow aggregating information are presented, which are called OWA and BON-OWA operators. The application of these operators is made in the selection of new product release. The main advantage of these operators is that they allow to capture the attitude of the decision maker and the continuous comparison and interrelation of the information. Thus, the holistic analysis offered by these methods on decision making in uncertainty is highlighted, which allows to integrate concepts of administrative and aggregation theories in an applied case, visualizing how the inclusion of information generates changes within the selection of alternatives.

The main purpose is to propose a new method for approximating the average interest rate using an ordered weighted average. The ordered weighted average (OWA), generalized GOWA operator and interval numbers are studied to develop this method. Using average interest rate formulation combined with aggregations operators and interval numbers presented above is the proposed weighted average interest rate (OWAIR) operator. For mathematical application, the deposit interest rates of the countries with 2020 data on the World Bank website are carried out. Finally, it should be noted that changes in the maximum, minimum, and average values are considered in the use of training for each region, which can be helpful for investors' decision-making.

The aim of this paper is to present the application of the OWA operator and some of its extensions in the calculation of continent and global tax revenues. The idea is to present how the analysis of an important economic indicator can vary depending on how the information is aggregated. An example was employed based on the Organization for Economic Co-operation and Development (OECD) database using 111 countries that were divided by continent, and then the global tax revenue was calculated using different aggregation operators. Different analyses can be carried out by governments and enterprises to improve decision making and fiscal politics. [ABSTRACT FROM AUTHOR]

This paper presents a new aggregation operator technique that uses the ordered weighted average (OWA), heavy aggregation operators, Hamming distance, and moving averages. This approach is called heavy ordered weighted moving average distance (HOWMAD). The main advantage of this operator is that it can use the characteristics of the HOWMA operator to under-or overestimate the results according to the expectations and the knowledge of the future scenarios, analyze the historical data of the moving average, and compare the different alternatives with the ideal results of the distance measures. Some of the main families and specific cases using generalized and quasi-arithmetic means are presented, such as the generalized heavy moving average distance and a generalized HOWMAD. This study develops an application of this operator in forecasting the sales growth rate for a commercial company. We find that it is possible to determine whether the company's objectives can be achieved or must be reevaluated in response to the actual situation and future expectations of the enterprise.

This paper aims to present a bibliometric analysis of the literature on an entrepreneurial intention that considers different topics to enhance starting a business. Using the Core collection of the Web of Science, 1,549 papers are found from 1900 to December 2020 to be analyzed. The analysis is focused on documents, authors, journals, countries, and keywords to detect areas and trends in this field of study. Likewise, bibliographic couplings, co-citation, and co-occurrences are analyzed. Findings show that the field has started to grow since 2010; the most influential authors and universities are in Spain and Taiwan, such as the case of Liñan, Liang, Ip, and Moriano.
