Ítem Análisis y comparación de alternativas para cuantificar el riesgo operacional(Universidad EAFIT, 2009) Franco Arbeláez, Luis Ceferino; Velásquez Ceballos, HermilsonÍtem ¿Cuáles son los determinantes de la tasa de cambio real en Colombia para el periodo 1985-2005?(2006) Franco, María Adelaida; Montoya, Tatiana; Zuluaga Díaz, Francisco IvánÍtem Definición de propuesta de valor para una PropTech para el análisis de riesgo en arriendo de vivienda en el Valle de Aburrá(Universidad EAFIT, 2024) Nicholls Molina, Santiago; Echeverry Gómez, SimónThe thesis defines a value proposition for a new PropTech focused on risk analysis in residential leasing in the Valle de Aburrá, Colombia. The research addresses high informality, lack of adequate legal protections, and scarcity of reliable tenant data, hindering market efficiency and security. Through interviews and surveys with landlords and tenants, the value proposition was designed using Osterwalder's Value Proposition Canvas. The concept of Self-Realty was identified, highlighting landlords' preference for greater control and autonomy, suggesting the creation of "PropioTech," a self-management platform. This proposal aims to improve market formalization and efficiency, promoting a sustainable and replicable business model.Ítem Development of a fragility model for the residential building stock in South America(EARTHQUAKE ENGINEERING RESEARCH INST, 2017-05-01) Villar-Vega, Mabe; Silva, Vitor; Crowley, Helen; Yepes, Catalina; Tarque, Nicola; Acevedo, Ana Beatriz; Hube, Matias A.; Gustavo, Coronel D.; Maria, Hernan Santa; Mecánica AplicadaSouth America-in particular, the Andean countries-are exposed to high levels of seismic hazard, which, when combined with the elevated concentration of population and properties, has led to an alarming potential for human and economic losses. Although several fragility models have been developed in recent decades for South America, and occasionally used in probabilistic risk analysis, these models have been developed using distinct methodologies and assumptions, which renders any direct comparison of the results across countries questionable, and thus application at a regional level unreliable. This publication aims at obtaining a uniform fragility model for the most representative building classes in the Andean region, for large-scale risk analysis. To this end, sets of single-degree-of-freedom oscillators were created and subjected to a series of ground motion records using nonlinear time history analyses, and the resulting damage distributions were used to derive sets of fragility functions. © 2017, Earthquake Engineering Research Institute.Ítem Development of a fragility model for the residential building stock in South America(EARTHQUAKE ENGINEERING RESEARCH INST, 2017-05-01) Villar-Vega, Mabe; Silva, Vitor; Crowley, Helen; Yepes, Catalina; Tarque, Nicola; Acevedo, Ana Beatriz; Hube, Matias A.; Gustavo, Coronel D.; Maria, Hernan Santa; Villar-Vega, Mabe; Silva, Vitor; Crowley, Helen; Yepes, Catalina; Tarque, Nicola; Acevedo, Ana Beatriz; Hube, Matias A.; Gustavo, Coronel D.; Maria, Hernan Santa; Universidad EAFIT.

These efforts led to the development of a repository of probabilistic seismic hazard models, a global exposure dataset comprising structural and occupancy information regarding the residential, commercial and industrial buildings, and a comprehensive set of fragility and vulnerability functions for the most common building classes. These components were used to estimate probabilistic earthquake risk globally using the OpenQuake-engine, an open-source software for seismic hazard and risk analysis. This model allows estimating a number of risk metrics such as annualized average losses or aggregated losses for particular return periods, which are fundamental to the development and implementation of earthquake risk mitigation measures. © The Author(s) 2020.Ítem Development of a global seismic risk model(EARTHQUAKE ENGINEERING RESEARCH INST, 2020-02-02) Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Acevedo, A.; EUCENTRE; GNS Science; US Geological Survey; Natural Resources of Canada; GFZ Potsdam; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Global Earthquake Model Foundation; Acevedo, A.; EUCENTRE; GNS Science; US Geological Survey; Natural Resources of Canada; GFZ Potsdam; Universidad EAFIT.

Evidencia para una empresa comercializadora en Colombia(Universidad EAFIT, 2024) Matiz Ruiz , John Jairo; Cruz Castañeda, Vivian; Álvarez, PilarÍtem Estudio de factibilidad de crear un centro de servicios compartidos para el sector funerario de Colombia, que tenga sede en Manizales(Universidad EAFIT, 2020) Mejía Ramírez, Juanita; Gómez Salazar, Elkin ArcesioIn the present document are presented the report of the research carried out in the Master in Project Manager at EAFIT University, which has the general objective to carry out a feasibility study for the creation of a Shared Services Center for the Funeral Sector of Colombia, which was based in Manizales. To achieve this, a descriptive and qualitative research methodology with quantitative elements was used, in which especially the variables of the financial study were measured, to facilitate the decision-making. In turn, the UNIDO methodology is the guide with which the feasibility study was developed. For the marketing study, a semi-structured survey was used, using non-probabilistic sampling. Also, the collection of information was complemented with interviews with experts in both the funeral and in the BPO sector. Taking into account not only the financial evaluation of the project but also the investor, in which it is established that the NPVs are positive and the IRR is greater than the discount rate in all scenarios, the analysis of all its components lets conclude that it is a viable and feasible project. It is recommended to carry out an adequate risk plan, as it is evident how these can significantly affect the results.Ítem Estudio de prefactibilidad para la creación de una empresa de limpieza y desinfección en Medellín, Colombia(Universidad EAFIT, 2023) Romero Tenjo, Diana Paola; Gómez Salazar, Elkin ArcesioThe objective of the present degree work is to analyze the pre-feasibility of creating a cleaning and disinfection company in the city of Medellín, through the implementation of the methodology for the preparation and evaluation of Onudi projects, for which a project investment through the detailed analysis of seven studies: sectoral, market, technical, organizational, legal, environmental, financial and risk analysis was developed. The results obtained in each study was framed by the significant changes in consumption habits after the covid-19 pandemic, which was experience worldwide from March 2019 to mid-2020. These changes included habits related to improvements in health and well-being, as well as in consumer promotion channels, where digital transformation forced companies to reinvent themselves to reach their customers through e-commerce. Teleworking allowed for greater connectivity between companies during this isolated period, which led to people spending more time in their homes, so families were encouraged to increase the consumption of cleaning products and to contract cleaning and disinfection services. This habit continued after overcoming the health crisis. In the case of Colombia, companies implemented biosafety protocols according to their economic activity, required by the Ministry of Health and Social Protection, which led to an increase in contracting with companies specialized in this field, to comply the required standards and protocols required to resume the face-to-face attendance. The previous panorama allowed an increase in the creation of cleaning service companies in the country, to satisfy not only the current demand in homes, but also in the business environment under new quality and service standards, key points that were taken into account throughout this investigation. Based on the previous studies and in a risk analysis, it is concluded that it is a low-risk project for the investor which makes it viable to execute the project.Ítem Estudio de previabilidad para la creación de una startup de domótica en Colombia(Universidad EAFIT, 2019) Gómez Angel, Ricardo; Díez Benjumea, Jhon MiguelThe objective of this work is to evaluate the prefeasibility of the project to create an startup in Colombia aimed at developing tailored and low-cost home automation solutions. With the study it is expected to obtain data that can make a decision regarding the most successful investment. For the work, the UNIDO methodology described in the Manual for the preparation of industrial feasibility studies was carried out.Ítem Evaluación del nivel de madurez en la gestión de riesgos en proyectos de la empresa Explanan(Universidad EAFIT, 2023) Aristizábal Isaza, Esteban; Gómez Salazar, Elkin ArcesioÍtem Medición cuantitativa de riesgo de mercado en instituciones no financieras(Universidad EAFIT, 2019) Angulo Martínez, Mario Germán; Correa Agudelo, XimenaIn this article, a quantitative measurement of financial market risk of four non-financial institutions listed on the Colombian stock exchange was carried out. Initially, the risk and different types of risk are defined, and then the article emphasizes in the risk market. Subsequently, recognized and studied methodologies are applied to measure the financial market risk and determine the expected return, volatility, value at risk (VaR), the conditional value at risk (CVaR) of each institution. Finally, from the results obtained is concluded that the Ecopetrol group is the institution that presents the most risk.Ítem Modeling added spatial variability due to soil improvement: Coupling FEM with binary random fields for seismic risk analysis(Elsevier Ltd, 2018-01-01) Montoya-Noguera, Silvana; Lopez-Caballero, Fernando; Mecánica AplicadaA binary mixture homogenization model is proposed for predicting the effects on liquefaction-induced settlement after soil improvement based on the consideration of the added spatial variability between the natural and the treated soil. A 2D finite element model of an inelastic structure founded on a shallow foundation was coupled with a binary random field. Nonlinear soil behavior is used and the model is tested for different mesh size, model parameters and input motions. Historical evidence as well as physical and numerical modeling indicate that improved sites present less liquefaction and ground deformation. In most cases this improvement is modeled as homogeneous; however, in-situ measurements evidence the high level of heterogeneity in the deposit. Inherent spatial variability in the soil and the application of some soil improvement techniques such as biogrouting and Bentonite permeations will necessary introduce heterogeneity in the soil deposit shown as clusters of the treated material in the natural soil. Hence, in this study, improvement zones are regarded as a two-phase mixture that will present a nonlinear relation due to the level of complexity of seismic liquefaction and the consequent settlement in a structure. This relation is greatly affected by the mechanical behavior of the soils used and the input motion. The effect on the latter can be efficiently related to the equivalent wave period as the proposed homogenization model depends on the stiffness demand of the input motion. © 2017 Elsevier LtdÍtem Modelos de pérdidas agregadas (LDA) y de la teoría del valor extremo para cuantificar el riesgo operativo teoría y aplicaciones(Universidad EAFIT, 2010) Arias Pineda, Guillermo León; Murillo Gómez, Juan Guillermo
