Ítem Análisis y mejora de la confiabilidad en intercambiadores de calor tipo AES en la refinería de petróleo Ecopetrol en Barrancabermeja(Universidad EAFIT, 2019) Dávila Hernández, Gustavo Julio; Mora Gutiérrez, Luis AlbertoÍtem Aproximación de la confiabilidad para optimizar procesos de mantenimiento y productivos con distribución Weibull(Universidad EAFIT, 2019) Pulgarín Sánchez, Sergio Andrés; Mora Gutiérrez, Luis AlbertoÍtem Diseño del soporte primario en túneles viales con un macizo rocoso con RMR entre 50 y 80 (GSI entre 43 y 75) aplicando métodos basados en la confiabilidad(Universidad EAFIT, 2022) Rivera Aguirre, Ana Carolina; Prieto Salazar, Jorge AlonsoIn a first stage, uncertain input variables were listed. Then, the most relevant variables for the excavation stability in tunnels were selected. These variables were characterized using their probability function, average and standard deviation values. A primary support design was made, in a virtual tunnel, using the typical section of a road tunnel with two lanes. This design contemplated a good quality rock mass, with a RMR (Rock Mass Rating) with values between 50 and 80 (GSI between 43 and 75). The primary support design considered tenso-deformational and fall wedge analysis. Two primary support alternatives were proposed. For each support alternative, two types of analyzes were carried out: deterministic and probabilistic. In deterministic analyses, the input data were the average values of the variables. In probabilistic analysis were used input random variables (including the excavation radius). Finally, a quantitative comparison, utilizing expected costs, between the two design alternatives was elaborated. According to the obtained results, it is possible to point out that reliability design methods are fundamental tools in the project evaluation risk. In the same way, the design with a probabilistic approach allows identifying variables with greater weight in the models used to evaluate stability and therefore focus efforts on having a detailed estimate of these random variables.Ítem Diseño y validación de una metodología de reparación y recambio de activos funcionales del área de mantenimiento en EPM(Universidad EAFIT, 2024) Garzón López , Duván Arley; Villegas López, Juan SantiagoÍtem Electric Energy Transmission Processes and the Importance of Integrated System Management and Operation(Universidad EAFIT, 2021) Horta Gómez, Oscar Julián; Dueñas Ramírez, Leidy Marcela; Villegas López, Gustavo Adolfo; Villegas López, Gustavo AdolfoElectric energy is fundamental in different sectors of a society's development; electric energy is used in all types of industries and economic sectors and is essential in people's homes, so access to a quality electric energy service in the city or in rural areas provides a reference index of a territory's level of development. For this reason, electricity transmission is considered one of the most relevant factors for improving the quality of life of the inhabitants of a country with a high poverty index. Electric power is a service that must be transmitted in a guaranteed manner with high standards of quality, reliability, and availability. This supports the economic development of a nation. This research focused on studying the efficiency of an organization that provides the service of transformation and transportation of electrical energy in Colombia and through this study to impact professionals, higher education institutions and companies to ensure their presence in the market, improving the quality of their graduates in different areas of knowledge such as physics and engineering and in parallel to provide companies with a guide that allows organizations dedicated to the electricity sector in Colombia to comply with existing regulations. This work highlights the need to perform mechanical, electrical, instrumental, operational and management processes with high standards for companies that provide electric power transmission service with equipment operating at voltages above 220 kV. Additionally, this research aims to establish a guide that allows organizations dedicated to the electric sector in Colombia to comply with current regulations.Ítem Estimación de la validez y la fiabilidad de un instrumento de evaluación oral(Universidad EAFIT, 2003) Muñoz Restrepo, Ana Patricia; Álvarez Villa, Martha Eugenia; Universidad EAFITÍtem Exploring the role of system operation modes in failure analysis in the context of first generation cyber-physical systems(Universidad EAFIT, 2018) Ruíz Arenas, Santiago; Horváth, Imre; Mejía Gutiérrez, Ricardo; Rusák, ZoltanÍtem Implementación académica de la especialización en mantenimiento industrial de la universidad Eafit a una turbina hidráulica tipo Francis(Universidad EAFIT, 2024) Fonseca Buriticá, Álvaro Andrés; Barbosa Pérez, Jaime LeonardoÍtem Strategic analytical dashboard architectural framework approach of the management maintenance - Palermo Sociedad Portuaria con norma europea UNE PNE-en-15341(Universidad EAFIT, 2021) Villamil Simancas, Milton Alkaid; Mora Gutiérrez, Luis Alberto
