Publicación Redistribución del almacén para mejorar la eficiencia en la preparación de pedidos mediante análisis ABC/XYZ y datos operativos(Universidad EAFIT, 2025) Molina Moreno, Jaime Andrés; Ramírez Echeverri, Sergio AugustoThis master's thesis proposes a method to improve logistical efficiency in industrial companies by reducing operational travel distances and increasing productivity in order picking processes. The proposed solution applies an ABC/XYZ classification based on historical data extracted from the ERP system of the case study company, considering both the economic value and the frequency of movement of items. This analysis was automated using a Python-based template executed in Google Colab, enabling the calculation of key metrics such as average picking time, number of order lines, and the distribution of items according to operational modality (storage or cross docking). The core of the proposal lies in a technical redistribution of the warehouse layout to position critical items in high-accessibility zones, thereby minimizing the distance traveled per order. Various operational improvement scenarios were simulated to forecast gains in daily capacity without increasing staff. The results show a 13.7% reduction in average travel distance per order and over 50% cost savings in operations under a 30% efficiency improvement scenario. The model is replicable, traceable, and highly compatible with warehouse management systems (WMS), providing tangible benefits for optimizing logistics processes in distribution centers.Publicación Diseño a flexocompresión de columnas empleando envolventes de respuesta sísmica vectoriales - Implicaciones normativas y económicas(Universidad EAFIT, 2024) Monroy Yepes, Alejandro; Jaramillo Fernández, Juan Diego; Risk and Design Consulting S.A.SThis paper presents comparative results of the structural design of reinforced concrete columns using 3 different methodologies for the calculation of the maximum expected seismic demands. The first one, corresponds to the design using the combination of the maximum values of axial load and bending moments obtained from a response spectrum modal elastic analysis; in the second one structural design is made for all the actions obtained from linear chronological elastic analyses; and the last one corresponding to the structural design using the envelope of vectorial seismic responses proposed by Menun and Der Kiureghian (2000). Each of the methodologies used is developed following the requirements defined in the Colombian Seismic Resistant Construction Regulation (NSR-10). As a result of the present article, the economic advantages (reductions up to 50% in reinforcement steel) obtained by using the method proposed by Menun and Der Kiureghian, which additionally, represents in a better way the maximum expected seismic vector response of the columns, are highlighted.Publicación Caracterización del comportamiento de concreto reforzados con macro fibras, en pavimentos, con materiales locales(Universidad EAFIT, 2024) Rodríguez Cruz, Arturo; Vidal Valencia, JuliánPublicación Determinación de módulo de reacción de subrasante para suelos finos saturados(Universidad EAFIT, 2024) Solano Rodríguez, César Miguel; Prieto Salazar, Jorge AlonsoN/APublicación Sistema de abastecimiento para minimizar los agotados en una empresa enfocada en distribución(Universidad EAFIT, 2024) Olaya Osorno, Gloria Matilde; Ramírez Echeverri, Sergio AugustoPublicación Análisis y mejora de procesos productivos para elaboración de prendas de vestir del sector textil mediante herramientas de manufactura esbelta(Universidad EAFIT, 2024) Ibarra Arrubla, Santiago; Arrieta Posada, Juan GregorioPublicación Metodología para la implementación de un Data Lakehouse(Universidad EAFIT, 2025) Aristizábal Diaz, José Mateo; Montoya Múnera, Edwin NelsonDegree ThesisPublicación Obtención de campos de desplazamiento y de rotación de una viga apoyada sobre suelo con rigidez variable lineal, mediante método de rigidez con funciones de green y transformada diferencial(Universidad EAFIT, 2024) Quintero Jaramillo, Javier Everardo; Molina Villegas, Juan CamiloBeam stressesPublicación Assessment of Simultaneous Accessibility Walking Index (SAWI) to essential opportunities(Universidad EAFIT, 2024) Miranda-Parra, Sergio Manuel; Ospina Zapata, Juan PabloPublicación Prueba piloto de mejoramiento para el proceso de tintas base agua y UV en la empresa Procoformas S.A(Universidad EAFIT, 2025) López Marín, Daniel; Ramírez Echeverri, Sergio AugustoPublicación Etiquetado de motocicletas nuevas para contribuir con los estándares de eficiencia energética en Colombia(Universidad EAFIT, 2025) Flórez-Durango, José David; Giraldo Galindo, Michael DanielThe study addresses the design of an energy labeling system for motorcycles in Colombia, aimed at promoting energy efficiency and reducing greenhouse gas emissions in the transportation sector, which represents a significant contribution to the country's energy consumption and emissions. Based on international experiences and a review of programs implemented in countries such as Brazil, Vietnam and Thailand, key strategies were identified, including fuel consumption regulation, tax incentives, and the promotion of clean technologies. This labeling system not only seeks to inform consumers about the energy efficiency of vehicles, but also to encourage manufacturers to adopt stricter standards and sustainable technologies, thus contributing to compliance with national decarbonization goals and international environmental commitments. Furthermore, the study highlights the impact of energy labeling policies in fostering responsible purchasing decisions and developing a more sustainable motorcycle market in Colombia.Publicación El impacto de las herramientas basadas en inteligencia artificial en la actividad profesional de las firmas legales, resultados de un mapeo sistemático de la literatura(Universidad EAFIT, 2025) Vásquez Mira, Juan Camilo; Suescún Monsalve, ElizabethPublicación Comportamiento de una mezcla asfáltica en frio elaborada con arcilla expandida(Universidad EAFIT, 2025) Rodríguez Useche, Bladimir de Jesús; Vidal Valencia, JuliánThe increasing need to use alternative aggregates to replace natural stone aggregates in the production of asphalt mixtures has led the road construction industry to evaluate the behavior of new materials, including expanded clays. This research evaluates the physical and mechanical behavior in the laboratory of a cold asphalt mixture (CMA) made with expanded clay, in which the natural aggregates were completely replaced by Arlita, expanded clay, and the bulk density, void percentage, permeability, abrasion loss, indirect traction, resilient modulus, elastic modulus and permanent deformation were measured. A comparative method was used to analyze the experimental results with the general specifications for road construction of the National Institute of Roads of the Republic of Colombia (INVIAS); the document also presents the benefits and limitations of the asphalt mixture.Publicación Plataforma web de Internet de las cosas para entornos educativos(Universidad EAFIT, 2025) Escobar Soto, José Alexander; Tamayo Vélez, Martín Alonso; Laboratorio de Mecatrónica y mecánica experimental, Universidad EAFITInternet de las cosas (IoT) es una tecnología que permite la interconexión de dispositivos a través de una red, ya sea entre sí o a través de internet. Esta interconexión facilita el control y monitoreo remoto de dispositivos en tiempo real, con aplicaciones que abarcan desde hogares inteligentes hasta sistemas industriales complejos de control de procesos y seguridad. En el entorno educativo actual, las instituciones de educación superior enfrentan desafíos significativos para formar profesionales capacitados en estas tecnologías. Para hacerlo se usan las plataformas IoT comerciales existentes las cuales imponen limitaciones como períodos de prueba limitados, capacidad limitada de datos y funcionalidades bloqueadas, para acceder todas las funcionalidades se deben parar costosas suscripciones. Para solucionar esta problemática, se desarrolla una plataforma IoT educativa completamente gratuita, diseñada específicamente para estudiantes de ingeniería, computación y áreas afines, esta plataforma no tiene ninguna de las limitaciones anteriormente mencionadas, adicionalmente la curva de aprendizaje para su uso no es tan alta como en otras plataformas.Publicación Modelo de adopción de transformación digital para Pymes(Universidad EAFIT, 2024) Solís Durango, Oscar Andrés; Tabares Betancur, Marta Silvia del SocorroIn recent years, SMEs have faced an accelerated digital transformation due to the benefits it brings to corporate resilience. However, this has not been easy, as it must be accompanied by a strategic process that involves cultural, organizational and technological changes at the corporate level. This article presents a digital transformation adoption model for SMEs made up of three components: organizational readiness, technological adoption, and cultural change; the model is based on the enterprise architecture discipline - TOGAF framework, and the COPRAS method. To achieve this, a literature review was carried out that allowed characterizing the digital transformation adoption processes for SMEs; this was complemented with a survey that allowed understanding the challenges, capabilities, opportunities and obstacles that SMEs face during this process. Once the model was defined, its possible adoption was validated among the participants of the initial survey. The results showed that, according to the components of the model, companies prioritize as initial capabilities: organizational impact, technological adoption, information security, comfort in using technology, technological talent and support from management that prioritize the metrics: ROI, cost reduction, information technology infrastructure, availability, leadership management and adaptation to change. Finally, it can be concluded in general that SMEs are willing to adopt and adapt a digital transformation process supported by TOGAF and COPRAS, since by being able to measure capabilities early, the model allows them to accelerate the digital transformation process in a more comprehensive and disciplined way.Publicación Comparativa de tiempos de respuesta : Graphql vs Rest con grandes volúmenes de datos(Universidad EAFIT, 2024) Ramos García, Miguel Fernando; Correa Botero, DanielIn application development, the performance efficiency of web services is essential due to its direct impact on loading speed, scalability and end-user experience. Previous research has explored web service communication technologies such as REST and GraphQL, without reaching a consensus on which one handles large data transfers more efficiently. The challenge is to determine which of these two web services communication technologies, REST or GraphQL provide faster response times for large data volume requests. To this end, it is proposed to compare both technologies under controlled conditions to identify which one offers better performance. The results of this study aim to provide clear guidance to those designing and developing applications, allowing them to choose the web services communication technology that best suits their needs and improves their users' experience.Publicación Comparativa de tiempos de respuesta: Graphql vs Rest con grandes volúmenes de datos(Universidad EAFIT, 2024) Ramos García, Miguel Fernando; Correa Botero, DanielIn application development, the performance efficiency of web services is essential due to its direct impact on loading speed, scalability and end-user experience.
