Metodología para la conformación de portafolio de acciones utilizando la técnica multicriterio de Borda

Este trabajo presenta la aplicación de la metodología multicriterio de Borda para la toma de decisiones en portafolio de acciones en el mercado bursátil colombiano. La problemática de esta investigación está relacionada con el diseño de una metodología para la toma de decisiones de inversión en mercados de renta variable considerando criterios de rentabilidad y riesgo. La metodología utilizada en la investigación incluye la integración de técnicas tradicionales y modernas de portafolio junto con la técnica multicriterio Borda. Dicha metodología permite evaluar un número de alternativas bajo una serie de criterios, asignando cierto puntaje de acuerdo con su posición relativa. La metodología propuesta se ha adaptado para la solución del problema de selección de portafolio de acciones en el mercado bursátil colombiano. Los resultados obtenidos muestran la eficiencia del método Borda para encontrar un equilibrio adecuado entre rentabilidad y riesgo.This paper presents the application of Borda’s multi-criteria decision-making method for stock portfolio in the Colombian stock ex-change. The research question addresses the design of a methodology for investment deci-sion-making in variable return markets by con-sidering return and risk criteria. The approach used includes the integration of traditional and modern techniques with Borda’s multi-crite-ria method; in this way, it allows assessing a number of choices under several criteria by as-signing a determined score according to their relative position. The methodology set forth is adapted for the problem of selecting a portfolio in the Colombian stock exchange. The results obtained show the efficiency of the Borda meth-od to find a suitable balance between return and risk

A fuzzy hierarchical multiple criteria group decision support system - Decider - and its applications

Decider is a Fuzzy Hierarchical Multiple Criteria Group Decision Support System (FHMC-GDSS) designed for dealing with subjective, in particular linguistic, information and objective information simultaneously to support group decision making particularly on evaluation. In this chapter, the fuzzy aggregation decision model, functions and structure of Decider are introduced. The ideas to resolve decision and evaluation problems we have faced in the development and application of Decider are presented. Two real applications of the Decider system are briefly illustrated. Finally, we discuss our further research in this area. © 2011 Springer-Verlag Berlin Heidelberg

ANALISIS FUNGSI BORDA UNTUK MENGETAHUI TINGKAT PENGETAHUAN TERHADAP KURIKULUM ABAD 21

This study aims to determine the extent of teacher knowledge about the 21st century curriculum by using the BORDA function. There are four skills and abilities namely communication, collaboration, critical and creative. The sample used was junior high and vocational school teachers in Batam. The results of his research communication skills have a greater percentage than other skills, namely for junior high school teacher communication knowledge by 43% and vocational school by 34%. Whereas in the SWOT analysis skills and communication skills are the strengths that both have a higher value than other indicators, both junior high and vocational high schools.This study aims to determine the extent of teacher knowledge about the 21st century curriculum by using the BORDA function.

Solving Civil Engineering Problems by Means of Fuzzy and Stochastic MCDM Methods: Current State and Future Research

The present review examines decision-making methods developed for dealing with uncertainties and applied to solve problems of civil engineering. Several methodological difficulties emerging from uncertainty quantification in decision-making are identified. The review is focused on formal methods of multiple criteria decision-making (MCDM). Handling of uncertainty by means of fuzzy logic and probabilistic modelling is analysed in light of MCDM. A sensitivity analysis of MCDM problems with uncertainties is discussed. An application of stochastic MCDM methods to a design of safety critical objects of civil engineering is considered. Prospects of using MCDM under uncertainty in developing areas of civil engineering are discussed in brief. These areas are design of sustainable and energy efficient buildings, building information modelling, and assurance of security and safety of built property. It is stated that before long the decision-making in civil engineering may face several methodological problems: the need to combine fuzzy and probabilistic representations of uncertainties in one decision-making matrix, the necessity to extend a global sensitivity analysis to all input elements of a MCDM problem with uncertainties, and an application of MCDM methods in the areas of civil engineering where decision-making under uncertainty is presently not common.The present review examines decision-making methods developed for dealing with uncertainties and applied to solve problems of civil engineering.

1st Doctoral Consortium at the European Conference on Artificial Intelligence (DC-ECAI 2020), 29-30 August, 2020 Santiago de Compostela, SpainThe DC-ECAI 2020 provides a unique opportunity for PhD students, who are close to finishing their doctorate research, to interact with experienced researchers in the field. Senior members of the community are assigned as mentors for each group of students based on the student’s research or similarity of research interests. The DC-ECAI 2020, which is held virtually this year, allows students from all over the world to present their research and discuss their ongoing research and career plans with their mentor, to do networking with other participants, and to receive training and mentoring about career planning and career option

Sistema multiagente para modelar procesos de consenso en toma de decisión en grupo a gran escala usando técnicas de soft computing

[ES]La presente Tesis se centra en el campo de los Procesos de Alcance de Consenso en Toma de Decisión en Grupo. En la literatura se han propuesto diversos modelos y enfoques para dar soporte a dichos procesos en problemas de toma de decisión en grupo reales, los cuales normalmente se han centrado en pequeños grupos de expertos. Sin embargo, dichos modelos presentan algunas dificultades:::;. y limitaciones para la gestión de grandes grupos. Dado que los problemas de toma de decisión en grupo a gran escala, en los que participa un elevado número de expertos, están cobrando una relevancia cada vez mayor en múltiples entornos tecnológicos, en esta investigación se propone un Sistema Multiagente basado en técnicas de soft computing, capaz de dar soporte en procesos de negociación semisupervisados, para alcanzar el consenso en problemas reales en los que participa un elevado número de expertos.[EN]This thesis focuses on the field of Consensus Reaching Processes within Group Decision Making. Several models and approaches have been proposed in the literature to support such processes in reallife group decision making problems, which have normally focused on small groups of experts. However, such models present some difficulties and limitations for the management of large groups. Due to the fact that large-scale group decision making problems, in which a large number of experts participate, are attaining an increasing relevance in multiple technological environments, this research proposes a multiagent system based on soft computing techniques, capable of giving support to semi-supervised negotiation processes in order to reach consensus in real-life problems in which a large number of experts take partoTesis Univ.

Generalizaciones y extensiones de la Regla de Votación de Borda

Se estudia la regla de votación de Borda clásica y variantes más sofisticadas que consideran preferencias graduales o lingüísticas en las opiniones de los agentes. Además se traza la evolución del método, prestando especial atención al análisis del precursor ilustrado José Isidoro Morales. El tratamiento histórico penetra el estudio teórico y hace patente la bondad de la regla de Borda frente a sistemas de votación al uso incuestionablemente peores, por ser más rígidos e incompletos. Como el método la Borda se implementa en dos fases (correspondientes a contadores individuales y colectivos en su formulación) se analiza su idoneidad atendiendo primeramente a la representatividad respecto de las preferencias individuales y a su relación con la transitividad de los agentes. Por otra parte, ya desde un punto de vista agregado, se realiza un análisis de tipo Condorcet. Finalmente se contrastan empíricamente los resultados anteriores, corroborándose y matizándose los aspectos teóricos tratadosDepartamento de Economía Aplicad
