Ítem Café especial, una alternativa para el sector cafetero en Colombia(Universidad EAFIT, 2019) Velásquez Agudelo, Camilo; Trávez Velásquez, Mateo; Dávalos Álvarez, EleonoraThe traditional coffee market has presented diffculties, given that its production and consumption tend to increase but prices decrease, generating losses for the coffee sector. In Colombia, coffee of the arabica species is cultivated in its entirety, which is the only species from which the specialty coffee comes, which, by exceeding a qualitative standard, overcomes the diffculties of traditional coffee, given that its price is higher, but the price is not The only benefit that is found in this special coffee market, there are also incentives, credits, technifications, consultancies that accompany the development of this market. Colombia has high points on important special coffee issues; by 2018, the average sale price was higher than USD10 $ per pound, ten times more than the traditional coffee price. This shows that a possible solution for coffee in Colombia would be the transition to special coffee crops, taking advantage of the history that the country has in this sector and the geographical conditions with which they are counted. Through higher prices, coffee farmers would have the incentive to make this transition, and not only focus on a market in which there are crisesPublicación Precision agriculture for grazing and animal health management : a case study in Colombia(Universidad EAFIT, 2023) García Hoyos, Rodrigo Junior; Aguilar Castro, José LisandroIn this research, we address the problem of fattening management and animal health in rotational grazing. For the study of this problem, we have positioned ourselves in the framework of the paradigm of precision farming, a technological approach that uses advanced information and communication tools and techniques to optimize agricultural and livestock production processes. In this context, precision livestock farming focuses on the use of technologies to improve grazing management and animal health on cattle farms. Some objectives of precision livestock farming are to increase farm efficiency and productivity, improve product quality and reduce production costs. In addition, it also contributes to environmental sustainability by enabling more efficient management of natural resources and reducing negative impacts on the environment. Although precision livestock farming offers many opportunities to improve efficiency and sustainability in livestock production, it also presents challenges that must be addressed for successful implementation. To address this problem, our objective was to develop methodologies, models, and approaches to support decision-making related to productivity management and animal health. To achieve this objective, several sub-objectives were raised, the first one was to develop a precision livestock farming architecture based on emerging technologies (Industry 4.0, artificial intelligence, etc.), the second on developing generic knowledge models of precision livestock farming for animal health and herding management and finally, in the third to develop meta-intelligent models for precision livestock farming in the context of autonomous grazing and animal health management. In general, several research articles were developed to meet the objectives proposed in this thesis. Initially, a review article on the latest trends in precision livestock farming using machine learning techniques was carried out. On the other hand, for the first specific objective, an article was conducted where three autonomous cycles of data analysis tasks based on autonomous computing were proposed for a beef production process for precision livestock farming. To meet the second specific objective, three articles were proposed. The first is a beef cattle weight identification model using machine learning techniques for anomaly detection, the second presented a system for monitoring the cattle fattening process in rotational grazing using fuzzy classification, in the third, a multi-objective optimization model was developed to maximize weight gain of cattle in rotational grazing. Regarding the third objective, three articles were developed, the first one proposed an autonomous cycle of data analysis tasks for the self-supervision of animal fattening in the context of precision livestock farming, and the second article presents a management system for the cattle fattening process in rotational grazing by means of diagnostic and recommendation systems. Finally, the last article proposed the use of the meta-learning paradigm in a cattle weight identification system for anomaly detection. In each article, we evaluated the strategies/models using various datasets. The results showed the capacity of the developed methodologies and models for decision-making in the management of the livestock production process. Specifically, our proposals allow the management of fattening and animal health in rotational grazing, considering, among other things, monitoring, diagnosis, and optimization of the productive process, with good results in performance metrics.Publicación Servitrasplantes: experiencias de una empresa innovadora en Colombia(Universidad EAFIT, 2013) Uribe Valencia, Mauricio; Henao Calad, MónicaEste caso presenta una situación real, en la que una familia con décadas de conocimiento en un oficio particular y años de investigación en los diferentes aspectos de un sistema de siembra que puede llegar a ser una salida de productividad para el sector arrocero colombiano, se lanza a hacer empresa con muchos elementos a su favor -- Las fortalezas: el modelo de negocio, la financiación, la relación con los proveedores y muchos otros de los factores críticos de éxito, considerados en el proceso de diseño del negocio -- Luego de comprometer su patrimonio en la importación de equipos y en consecución de créditos de capital de trabajo y haber lanzado el negocio, el grupo comenzó a ver, después del segundo año, cómo factores culturales y presiones de grupos con intereses particulares empezaron a bombardear el sistema hasta lograr dañar la imagen del mismo -- La situación financiera desesperada, las presiones de los banco y la situación de deterioro de la maquinaria llevaron a los protagonistas de la historia a plantearse varias alternativas y a buscar por todos los medios posibles, una salida en la que el entorno se presenta cada vez más difícil -- Los protagonistas deben enfrentar el fantasma de la desaparición, o buscar todo tipo de alternativas para reinventar la compañía y salir adelante -- El caso plantea también una problemática crítica de un sector en Colombia, como el arrocero, del cual hoy viven cerca de 500.000 familias, el cual pasó en unos pocos años de ser exportador a una situación actual de ineficiencia y vulnerabilidad, con tendencia a desvanecerse con los Tratados de Libre Comercio -- El lector, como consultor externo y teniendo en cuenta la información disponible tanto del entorno como de la empresa, deberá realizar un análisis de alternativas de acción y presentar a la Junta las más viables
