Item type:Publication, Caracterización de la productividad de una empresa mexicana desarrolladora de tecnología mediante control difuso(2022) ;Cabrera Llanos, Agustín Ignacio ;Mayo Maldonado, JonathanSe presenta el desarrollo de un modelo que permite medir la productividad de una empresa de base tecnológica, que se basa en las interacciones identificadas entre la inversión del departamento de investigación, el fraude informático y el robo. Estas interacciones se presentan mediante un modelo de variables difusas con las que se desarrollan las funciones de membresía para cada una de éstas. Así mismo se desarrollan las reglas de interacción basándose en la conjunción de los conjuntos difusos propuestos para el modelo Mamdani. Con estos diseños es posible determinar el grado de la productividad, también caracterizada por un conjunto difuso. Para probar el modelo se utilizó simulación Monte Carlo con cuatro escenarios. Los resultados de la serie de simulaciones muestran que bajo la descripción de los conjuntos difusos es posible medir el comportamiento de la productividad en la empresa analizada, mediante rangos de productividad establecidos en el diseño del conjunto difuso propuesto.24 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Un modelo de minimización de costos de mantenimiento de equipo médico mediante lógica difusa(2019) ;Cabrera Llanos, Agustín Ignacio; Cruz Aranda, FernandoThis paper presents an algorithm based on fuzzy logic that models a Maintenance Management Plan of Medical Equipment, this is developed in three stages: In the first one, a functional inventory is generated, following the protocols recommended by the WHO and information of each team. In the second, three priority attention protocols are attached, used to select the diffuse system membership functions. In the third, a family of scenarios is generated by Monte Carlo simulation, calculating the degreeof fuzzy maintenance priority for the equipment. The results achieve that the equipment selection of the annual maintenance plan is carried out guaranteeing the availability of the priority equipment. In this article, the application of the Fennigkoh-Smith algorithms and the Wang-Levenson algorithm are improved by placing the ambiguity of the diffuse structure, making the selection of the medical equipment incorporate the range of possibilities that exist when selected in an arbitrary manner. An area of opportunity consists of incorporating a process of optimization of equipment maintenance costs with a budgetary restriction. It is concluded that the system shown is friendly and robust for the purposes proposed.Scopus© Citations 3 28 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Historical identification and forecast values of IBEX 35 & IPC financial indices using differential neural networks(2012); Cabrera Llanos, Agustín IgnacioOne of the main objectives of quantitative analysis in Finance is to be able to make accurate forecasts of prices and yields from financial assets, the question is to find reliable methods and techniques to perform properly such forecasts. In the early 1990 ́s while pursuing better results the use of artificial neural networks (ANN) started, this technique was only used as a tool of monitoring and description of values, but later it evolved into a way of forecasting the behavior of economic and financial variables, achieving promising results. In this paper we present one of the first applications in finance of the Differential Neural Networks (DNN), we use that to carry out two processes: the description of daily closing values of financial index IBEX 35 (Madrid Stock Exchange) and the IPC index (Mexican Stock Exchange), both from January 3, 2000 to January 20, 2012. Later, we perform the forecast of daily closing values of these indices from January 23 to February 17, 2012. The results obtained in the description and forecast of the closing values of both indices were excellent, which makes it extremely attractive to continue the study of this methodology to carry out these forecasts.15 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Project Valuation of a Distribution Centre of an Auxiliary Rail Freight Terminal: Using Real Options with Fuzzy Logic and Binomial Trees(2016) ;Cruz Aranda, Fernando; Cabrera Llanos, Agustín IgnacioThis paper presents the financial evaluation of the extension of an auxiliary rail freight terminal to integrate it to a logistics platform (LP). This investment phase is focused on building a distribution center (CEDI), as part of a comprehensive project of high commercial and strategic impact for Mexico. The project evaluation is done using binomial trees for the valuation of an American type real call option, incorporating the expected volatility over the expected cash flows, in order to determine the benefit of postponing the project three years. In addition, to complement this real option valuation, we incorporate the fuzzy logic theory in the process of assigning probabilities to the branches of tree. The value of the American type real call option to postpone the project three years is 30.37% of investment, while the value of real option, using fuzzy logic is 29.94% of investment, this is a better result. © 2016, ASERS Publishing House.

Item type:Publication, Las finanzas de los hogares mexicanos: análisis con Redes Bayesianas(2021); ; Cabrera Llanos, Agustín IgnacioEl bienestar de los hogares está ligado en gran parte al desarrollo de los mercados financieros. El estudio de las finanzas de los hogares analiza las formas en que estos utilizan instrumentos financieros para satisfacer sus necesidades y objetivos; este análisis representa un gran desafío debido a la escasa información estadística y la interrelación entre las variables consideradas. En este trabajo, pionero en el uso de las redes bayesianas en este campo, utilizamos de manera conjunta las finanzas tradicionales y las conductuales. Medimos la probabilidad de prevalencia de estabilidad financiera de los hogares en México; obtenemos un resultado base y posteriormente, al generar distintos escenarios, descubrimos que las variables más determinantes son el manejo del crédito y la conformación de los hogares. Estos resultados subrayan la importancia de promover iniciativas de educación financiera en los distintos niveles, modalidades y subsistemas educativos. © 2021 Universidad Nacional Autónoma de México. In today's economy, the well-being of households is considered to be linked mainly to the development of financial markets. The field of household finance analyzes how households use financial instruments to satisfy their needs and achieve objectives. This analysis represents a significant challenge due to scarce statistical information and the interrelation among the variables involved. We follow two aspects: Traditional and behavioral finance. This paper pioneers the use of Bayesian networks in the field. A model measuring the probability of prevalence of financial stability of households in Mexico is used; a baseline result is obtained and then, while generating different scenarios, we discover that credit management and household composition are the most determining variables. These results underscore the importance of promoting different financial education initiatives at different educational levels, modalities, and subsystems. © 2021 Universidad Nacional Autónoma de México.Scopus© Citations 2 14 2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Reversión a la media en las series de precios reales del petróleo en México(2019) ;Ramírez Sánchez, José Carlos ;Cruz Aranda, FernandoCabrera Llanos, Agustín IgnacioEl objetivo de este documento es mostrar la existencia de un patrón de reversión a la media en la serie de precios reales del petróleo exportado por México al continente Americano, durante el período comprendido entre Enero de 1999 y Junio de 2017. Con ese fin adaptamos una ecuación en diferencias estocástica a la serie de precios de la variedad Maya para hacer pronósticos dentro y fuera de la muestra, con una ventana de seis y doce meses. Los principales resultados obtenidos muestran que, en efecto, hay una reversión a la media de largo plazo en los precios inicialmente supuestos como racionales. Otras pruebas estadísticas confirman que esta reversión a la media es persistente en virtud de que los shocks producidos sobre los precios reales no involucran cambios permanentes.Scopus© Citations 1 15 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Euro exchange rate forecasting with differential neural networks with an extended tracking procedure(2016); ;Cabrera Llanos, Agustín IgnacioVenegas-Martínez, FranciscoThis paper develops a new kind of non-parametrical artificial neural network useful to forecast exchange rates. We departure from the Differential Neural Networks (DNN) framework and extend the tracking procedure. Under this approach, we examine daily closing exchange rates of Euro against US dollar, Japanese yen and British pound. With our proposal, extended DNN or EDNN, we perform the tracking procedure from February 15, 1999, to August 31, 2013, and, subsequently, the forecasting procedure from September 2 to September 13, 2013. The accuracy of the obtained results is remarkable, since the error percentage in the forecasting period varies from 0.001.Scopus© Citations 1 34 2
