Ítem Adecuación de una metodología para incorporar movilidad empresarial a través del mejoramiento de los procesos de negocio(Universidad EAFIT, 2016) Cardona López, Diana Cristina; Cardona Ríos, SoniaÍtem Collaborative tools for global design project management: case study of an academic experience(2010-06-20) Mejía Gutiérrez, Ricardo; Esparragoza, Iván E.; Rodríguez Arroyave, Carlos Arturo; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Ingeniería de Diseño - GRIDThe management of information and the capture of design ideas are very critical during theproduct development and product lifecycle management -- They could be very challenging tasks when time, efficiency and quality are important and the concurrent design team is physically distributed in different locations -- However, the existing technology for communication, the increase of tools over the Internet and the cloud computing model have made possible and accelerated the means of sharing information synchronous and asynchronously in a very effective way -- This has facilitated the work of teams that in many cases are geographically dispersed around the world -- Therefore, there is a need to start preparing the future engineers in the use of collaborative tools for global design project management not only to schedule and coordinate all the required tasks for the project but also to capture all the information, ideas and concepts generated during the design process which contains valuable data that supports design decisions -- This paper presents the use of several tools for communication and project management used in academic collaborative global design projects -- In these projects, students are required to work with international partners from different universities in coordinating activities and documenting the conceptual design for a given problem -- The paper reports the experience using the tools and discusses opportunities and pitfalls in the use of them as they were identified by the authorsÍtem Diseño y construcción de la interfase física de usuario para un simulador virtual de cirugía laparoscópica(Universidad EAFIT, 2007) Posada Salazar, Daniel Fernando; Trefftz Gómez, HelmuthÍtem Estudio de factibilidad para la prestación de software ERP como servicio basado en Cloud Computing en la Pequeña y Mediana Empresa de la ciudad de Medellín(Universidad EAFIT, 2014) Zapata Ocaña, Álvaro; Vergara Kerguelén, Raúl; Henao Cálad, Mónica; Gómez Salazar, Elkin ArcesioLos sistemas de planificación y control de recursos empresariales conocidos como ERP (por sus siglas en inglés), han influido en la competitividad de las compañías desde la década de los ochenta -- Estas aplicaciones integradas han ayudado positivamente a la toma de decisiones en el proceso productivo ya que consolidan de forma integral toda la información de los procesos de negocio -- No obstante, la adquisición de este tipo de tecnologías requiere de grandes inversiones para implementarlas, mantenerlas y operarlas -- Para el caso de la pequeña y mediana empresa las posibilidades para acceder a estos sistemas han sido prácticamente imposibles debido a los altos costos de adquisición y sostenimiento -- Esto ha limitado el desarrollo de sus operaciones debido a que la carencia de información ágil y oportuna compromete la competitividad y visión de los negocios -- El presente estudio permite analizar la factibilidad de una empresa que ofrezca a la pequeña y mediana empresa de Medellín mecanismos informáticos que hasta ahora han sido de beneficio para la gran empresa -- Para llegar a esto se ha tomado como palanca tecnológica el concepto: cloud computing, el cual ofrece posibilidades para acceder a la información de la organización de forma remota sin tener que realizar inversiones en servidores, almacenamiento de datos y equipos de telecomunicaciones; adicionalmente, con el aprovechamiento de economías de escala, alienado con un óptimo diseño de Software ERP en la Nube, las Pymes verán en esta propuesta un modelo competitivo y económicamente viable para sus procesos integrales de mejora continuaÍtem Evolución e impacto de Cloud Computing en empresas grandes de diferentes industrias del sector corporativo en Antioquia(Universidad EAFIT, 2015) Arango Moreno, Carolina; Rincón Bermúdez, Rafael DavidÍtem Handling Heterogeneity in Collaborative Networked Surgical Simulators(Universidad EAFIT, 2016) Díaz León, Christian Andrés; Trefftz Gómez, HelmuthStand-alone and networked surgical virtual reality based simulators have been proposed as means to train surgical skills with or without a supervisor nearby the student or trainee -- However, surgical skills teaching in medicine schools and hospitals is changing, requiring the development of new tools to focus on: (i) importance of mentors role, (ii) teamwork skills and (iii) remote training support -- For these reasons, a surgical simulator should not only allow the training involving a student and an instructor that are located remotely, but also the collaborative training of users adopting different medical roles during the training sesión -- Collaborative Networked Virtual Surgical Simulators (CNVSS) allow collaborative training of surgical procedures where remotely located users with different surgical roles can take part in the training session -- To provide successful training involving good collaborative performance, CNVSS should handle heterogeneity factors such as users’ machine capabilities and network conditions, among others -- Several systems for collaborative training of surgical procedures have been developed as research projects -- To the best of our knowledge none has focused on handling heterogeneity in CNVSS -- Handling heterogeneity in this type of collaborative sessions is important because not all remotely located users have homogeneous internet connections, nor the same interaction devices and displays, nor the same computational resources, among other factors -- Additionally, if heterogeneity is not handled properly, it will have an adverse impact on the performance of each user during the collaborative sesión -- In this document, the development of a context-aware architecture for collaborative networked virtual surgical simulators, in order to handle the heterogeneity involved in the collaboration session, is proposed -- To achieve this, the following main contributions are accomplished in this thesis: (i) Which and how infrastructure heterogeneity factors affect the collaboration of two users performing a virtual surgical procedure were determined and analyzed through a set of experiments involving users collaborating, (ii) a context-aware software architecture for a CNVSS was proposed and implemented -- The architecture handles heterogeneity factors affecting collaboration, applying various adaptation mechanisms and finally, (iii) A mechanism for handling heterogeneity factors involved in a CNVSS is described, implemented and validated in a set of testing scenariosÍtem International multidisciplinary collaborative project for design of conceptual products(2011-07-06) Mejía Gutiérrez, Ricardo; Osorio Gómez, Gilberto; Sierra Zuluaga, Luis Fernando; Atkinson, Peter; Universidad EAFIT. Departamento de Ingeniería de Diseño; Peter Atkinson (arx050@coventry.ac.uk); Ricardo Mejia (rmejiag@eafit.edu.co); Gilberto Osorio (gosoriog@eafit.edu.co); Luis Fernando Sierra (lsierraz@eafit.edu.co); Ingeniería de Diseño - GRIDNowadays, due to globalization, the design and development process of complex systems demands distributed multidisciplinary work in order to improve product quality -- Within the university contextstudents are generally trained to work in groups, however, they often develop their academic projects with classmates of the same curricular program and the real industrial work situation is new for them -- To make this experience more realistic, EAFIT University in Colombia and Coventry University in the United Kingdom have joined to set-up and develop an international collaborative project course -- Two different disciplines have been paired, the engineering approach from Colombia and the industrial design competencies from the UK -- In a recent project, a real industrial need was used to reinforce the real life constraints in order to expose students to a realistic engineering and design approach -- The collaborative experience was strengthened with the co-location of all students after the UK participants travelled to Colombia for the final part of the project -- Results are analyzed in this article showing a good international cooperation scenario that enhanced the competitive level of students involved, as well as offering practical and creative solutions to local industryÍtem Process improvement in a virtual organization focused on product development using collaborative environments(2006-05-17) Galeano, Nathalie; Peñaranda Verdeza, Nicolás; Mejía Gutiérrez, Ricardo; Romero Diaz, David; Molina Gutiérrez, Arturo; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Ingeniería de Diseño - GRIDCollaborative Engineering Environments (CEE) have become really important in Virtual Organizations (VO) because they enable the coordination and collaboration among engineering groups, supported by tools and methodologies that enable intellectual capital sharing and engineering activities in real time, among organizations regardless of their locations -- A platform that integrates and facilitates the operation in Virtual Organizations focused in manufactured product development, is an important tool that supports a rapid respond to customers, and improve the communication among its members -- This paper present a way to improve business process in a VO based on the development and use of a CEE -- The methodology presented in this paper was implemented in a real manufacturing VO, improving the product transfer process: the coordinators of each business opportunity easily manage VO information, and VO partners were totally involved during the processÍtem Técnicas y herramientas para la gestión de las comunicaciones en equipos virtuales durante la ejecución de proyectos globales(Universidad EAFIT, 2014) Uribe Vélez, Daniel JoséUno de los factores de éxito más importantes en la gerencia de proyectos es la gestión de las comunicaciones ya que se tiene identificado que uno de cada cinco proyectos fracasa debido a una mala gestión en esta área -- Este factor toma aún mayor importancia cuando los proyectos tienen como características principales que son globales y los equipos son virtuales dadas las dificultades que traen consigo este tipo de proyectos, especialmente en la gestión de las comunicaciones -- En este trabajo se presenta una recopilación de las diferentes técnicas y herramientas que, según el concepto de varios autores, son comúnmente utilizadas para la gestión de las comunicaciones durante la ejecución de proyectos globales con equipos virtuales -- Con la información recopilada se hace finalmente una propuesta de un conjunto de técnicas y herramientas que pueden ser utilizadas por los gerentes de proyectos para la gestión de las comunicaciones durante la ejecución de este tipo de proyectos -- Este conjunto de técnicas y herramientas se deja como una hipótesis propuesta para una futura investigación que verifique su efectividad en ambientes reales de ejecución de proyectos globales con equipos virtualesÍtem Virtualización de Centros de Cómputo en universidades privadas de Medellín(Universidad EAFIT, 2009) Giraldo Raigoza, Andrés; Gómez Toro, Juan Esteban; Montoya Pareja, José Luis
