- PublicaciónAcceso abiertoAsistencia de investigación: estado del arte para el diseño de una cadena de recuperación de llantas usadas en el contexto local considerando las perspectivas de la gestión de residuos(Universidad de Ibagué, 2019) Gracia Prada, Luisa Valentina; Ramírez Rubio, Angie Marcela; García León, Andrés AlbertoThe problem of this research focuses on the inefficient management of waste tires used in the city of Ibagué. This problem not only affects the environment, but also misses business and employment opportunities, important factors for sustainable development in a region. In this order of ideas, for the design of a tire recovery chain used in the urban context, different aspects should be considered, such as the efficient management of waste as a source of value generation after the consumption phase. In order to build a waste management plan in Ibagué, it is necessary to know the different systems worldwide and adapt them so that they work under the conditions of the city, knowing the successful referents of waste management that have been implemented by developed cities. The objectives of this research are: 1) Determine the conceptual bases (theoretical framework) necessary for the design of an inverse supply chain from the perspective of waste management, 2) Identify and explain empirical cases in which they have been formulated or designed waste management systems for a supply chain and, finally, 3) Identify the relevant aspects that must be taken into account when designing a supply chain that is dedicated to the recovery of used tires. These objectives will be met through a systematic review of the literature of scientific articles related to the perspective of waste management. The present work contributes to the solution of the problem addressed in the macro project because it presents the information and relationship between the relevant concepts for the study, which in turn can have a general perspective of how has been the evolution in this field of knowledge, facilitating their understanding for the development of the present project. In addition, a systematization of the cases in which solid waste management has been developed in different regions is presented and how this influences both the environmental impact of the area and the generation of employment and income for the community involved. The aforementioned provides the research with a frame of reference for selecting the most appropriate methodologies considering the context of the city of Ibagué through the study of the methods used by other authors. Additionally, the knowledge of other research provides the present project with the fields that have not been studied before and the research gaps that, in turn, open the way to design waste management systems with different and new aspects to consider.

- PublicaciónAcceso abiertoAsistencia de investigación: Herramienta computacional con enfoque paretiano para minimizar el makespan y la tardanza máxima en el problema de scheduling Job-shop Flexible(Universidad de Ibagué, 2019) Lozada Rueda, Juan Sebastian; García León, Andrés AlbertoIn the present research assistance, one of the Job-shop extensions is studied and it is the consideration of flexibility, which is reflected in the possibility that an operation can be processed in a machine, which is selected from a subset of the total number of machines. The general objective is to design a computational tool to solve the problem by optimizing Makespan-Maximum tardiness, which is based on the results of the research of (García-León, Dauzère-Pérès, & Mati, 2016). The construction of this heuristic is based on a local search process and for this, three specific objectives were proposed. The first specific objective is to propose a set of metrics to measure the quality of the Pareto front for the problem of the multi-objective flexible Job-shop. The second is to design an algorithm to update the undominated solutions that are located on the frontier front, which added to it is not known for the problem, and finally, the formulation of search strategies. For this assistance, it has not been considered to solve a specific problem linked to an industrial process and its scope is only limited to solving the problem in instances of literature. To calibrate the parameters of the heuristic, the most complex instances of solving found in the scientific literature have been considered (Dauzère-Pérès et al., 1998).

- PublicaciónAcceso abiertoCaracterización de la cadena de recuperación de aceite usado proveniente del sector automotriz en el contexto urbano. Caso de Ibagué(Universidad de Ibagué, 2020) Serrato Escobar, Carlos Danilo; González Avilés, Jorge Iván; García León, Andrés AlbertoAn investigation was carried out that sought to characterize the chain for the recovery of used oil from the automotive sector in the urban context (Ciudad de Ibagué). The final disposal of used oil is a problem of global interest due to the increasing pressure towards the preservation of the environment and sustainable development, which implies the importance of efficient waste management (reduction, reuse and recycling) as a source of value generation in the local context. The characterization of the recovery chain implied the fulfillment of the following specific objectives. The first one consisted of carrying out a benchmark analysis of good practices for the design of a used oil recovery chain that allows identifying key aspects for its characterization in urban contexts. In the second objective, the aim was to characterize the actors that intervene in the recovery chain that allows their representation in the context by conducting surveys and interviews that were carried out in different services in the city (places where the oil changes). Finally, a diagnosis was carried out that allows the environmental, social and economic problems existing in the recovery chain of used oils in Ibagué to be dimensioned by analyzing the information collected and thus formulating strategies to mitigate the impact of said waste. For the research work, a total of 20 places that provide the service of automotive oil change were visited, which were divided into servitecs and local workshops. Based on the information obtained in each of them, the oil collection calculations for each of the two companies (Atica y Combustibles Juanchito) were estimated, which resulted in 34.08 drums per month and each drum has a capacity of 55 gallons, therefore 1874.4 gallons / month are collected.
- PublicaciónAcceso abiertoCaracterización de la cadena de recuperación de botellas de vidrio en el contexto urbano caso de Ibagué(Universidad de Ibagué, 2021) Díaz Cifuentes, Juan Diego; Rubio Ospina, Leidy Carolina; García León, Andrés AlbertoThis research is focused on the characterization of the supply chain of glass bottles in the city of Ibagué from the point of view of reverse logistics. The purpose is to know the benefits generated by its recovery and how these influence the economic, social and environmental factors of the city. Being the environmental factor the most affected, considering that in Colombia "about 12 million tons of garbage is generated annually, of which only 8.6% is recycled." The research has 3 specific objectives, in which the conceptual bases and premises that intervene in the characterization of this recovery chain were established through the development of legal and theoretical frameworks. These sections contain background and key concepts for the investigation. In addition, the actors, roles, stakeholders and their interrelationships involved in the recovery of glass bottles were determined. The information was obtained from personal interviews and reports published by the companies of interest and an evaluation was carried out to diagnose the impact of the recovery chain to develop strategies through the SWOT and MAFE matrices.
- PublicaciónAcceso abiertoCaracterización de la cadena de recuperación de botellas plásticas provenientes del consumo de agua y bebidas en el contexto urbano. Caso Ibagué.(Universidad de Ibagué, 2020) Ariza Espitia, Andrea Carolina; Rojas Trujillo, Anggie Nathalia; García León, Andrés Albertopresent work of degree is a research that aims to characterize the inverse chain for the recovery of plastic bottles from the consumption of water and soft drinks in the urban context (City of Ibague). Field visits were carried out, where it became clear that the final disposal of the bottles is a very notorious environmental problem, which leads to the importance of efficient waste management (reduction, reuse and recycling) as a source of added value generation in the urban context. A compilation of information was carried out through the database and the current Colombian environmental standard related to integrated waste management, which serves as a guide for the implementation of the environmental proposal for the recovery of plastic packaging, the aim being to characterise the actors involved in the recovery chain when learning about value generation alternatives, enabling them to be represented in the context by means of surveys and interviews aimed at different public or private entities or organisations, which serves as a guide for the analysis of favourable factors and allows a good result to be obtained in the case of the recovery of plastic bottles. A diagnosis is also made to assess the environmental problem, social and economic value in the recovery chain to be able to determine the economic value it generates by analyzing the information collected to design and implement solutions strategies. The aim of the project is to formulate proposals for the recovery of plastic bottles that will guide the organizations in the use of the packaging, bearing in mind the added value and the sustainable development it can generate.
- PublicaciónAcceso abiertoCaracterización de la cadena de reutilización de residuos generados en el sector de construcción y demolición (RCD) en la ciudad de Ibagué(Universidad de Ibagué, 2021) Claros Guzmán, Diego Fernando; Villanueva Duarte, Karen Daniela; García León, Andrés AlbertoThe research work was aimed at characterizing the chain of reuse of waste generated in the construction and demolition sector (RCD) in the city of Ibagué; In order to fulfill this objective, the studies carried out regarding the design of reverse supply chains of RCD were reviewed to have the conceptual bases necessary for said characterization, then the current regulations regarding the comprehensive management of such waste were consulted. In this case, resolution 472 of 2017, based on this, the actors involved in each of the links of the chain in the city of Ibagué were identified from generation and use to final disposal. By having contact with the main actors in the chain, the estimate of the amount of RCD that was generated in total was determined, as well as what was taken to final disposal and what was thrown into the environment, with these results it was obtained that most of the waste generated belongs to excavation land that is reused for leveling the terrain of new constructions, it was also detailed that there are economic benefits after the sale of materials such as iron and reduction of costs for reuse of concrete, finally identified that the environmental impact of such wastes is significant since those that are not used are taken into the environment causing health problems and in the same way contamination of the soil, water and air.
