Item Modelo lean manufacturing para la eliminación de desperdicios en la empresa Curtiembre Aldas(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2025-02) Peñafiel Ibarra Juan Carlos; Ortiz Guerrero Daysi MargaritaThis project presents a proposal for implementing Lean Manufacturing methodology at Curtiembre Aldas, located in the Tungurahua province of Ecuador. The company specializes in transforming cattle hides into finished leather for footwear and clothing. The main focus of this proposal is to eliminate non-value-adding activities, targeting key wastes such as unnecessary movements, excessive transport, and waiting times. Through the use of Lean tools, these issues within the company were addressed effectively. The research suggests the application of the 5S methodology to improve workstations by introducing manuals and systems for order and cleanliness. This approach aims to minimize time lost searching for tools or cleaning equipment, resulting in a significant 35.6% improvement compared to the company’s initial performance. As part of the SMED methodology implementation proposal, internal activities were converted into external ones, effectively organizing the necessary tools and equipment at the workstations. This led to reduced machine changeover times: from 25.83 minutes to 15.11 minutes on the splitting machine, from 68.44 minutes to 46.54 minutes on the trimming machine, and from 31.42 minutes to 19.06 minutes on the fleshing machine. Following the implementation of both methodologies, noticeable improvements were achieved in the production processes of Curtiembre Aldas, particularly in the ribera area.Item Análisis de metodología lean manufacturing para el mejoramiento de la productividad en el proceso productivo del calzado en industria Vecachi(Universidad Técnica de Ambato.

Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2022-09) Shambi Ortiz, Juan Pablo; Naranjo Chiriboga, Israel ErnestoThe plant layout is the way to properly locate machines, tools and workers to make the best use of the resources available to the industries. The main objective of this research project is to propose an adequate distribution of facilities for an industrial workshop dedicated to metalworking in different areas such as locksmithing, structuring and stainless steel, which is adapted to the production of the products offered by the workshop, reducing time and unnecessary transfers. In order to achieve these objectives, data is collected by means of information gathering techniques to know the current status of the company, its processes, products, etc., and then we proceed to obtain its star products and determine the standard time for each one of them. The appropriate type of distribution is selected with selection matrices and by means of the ordering and evaluation algorithms the appropriate distribution for the workshop is chosen, then the surface required for the distribution is established with the help of Guerchet's method and two alternatives are proposed, which are evaluated by means of the distance load method. By means of a selection matrix, the lean methodology tools are incorporated to the proposal, and with the help of the FlexSim simulation, the results obtained are compared between the current situation of the company and the proposed proposal. It is estimated that the time reduction is presented in 4.35% and the process routes in 69.87%, therefore, for this investment an investment of $22,080.00 is required with a recovery time of 1 year and 36 days.Item Optimización de los indicadores de productividad de los procesos de manufactura de una empresa láctea mediante la simulación con Flexsim integrando la filosofía Lean Manufacturing(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Matemática Aplicada, 2021) Flores Cadena, Cristian Andrés; Benalcázar Palacios, Marco EnriqueThe objective of this research is to simulate the manufacturing processes of the dairy company Soprab with the integration of the Lean Manufacturing Philosophy. One of the important advantages of simulation is to generate changes in the process without the need to make investments in companies. For the simulation, the data of the manufacturing processes of the yogurt and mozzarella cheese production lines were collected, through an on-site visit of the production plant. During this visit, data was collected on: number of operators, process times, equipment and machinery of the production lines and production batches. The simulation was carried out in the yogurt and mozzarella cheese production lines due to their high demand compared to the other products of the company. For the simulation, the Flexsim program was used, where the data collected in the plant was loaded. The simulation process was validated, with which it is concluded that the simulation carried out reflects the operation of the real process, where the initial productivity indicators were: cycle time equal to 687 min and productivity of 0.88 units / min in the line for making yogurt; while in the mozzarella cheese production line the initial values were: cycle time equal to 2339 min and productivity of 0.427 units / min. Then simulations of the improvement scenarios were carried out, incorporating Lean Manufacturing in the production lines such as: TPM, Poka Yoke, 5 S, elimination of mudas, kaizen and SMED. It was determined that the incorporation of the Lean Manufacturing philosophy did have significant statistical differences in the productivity indicators between the simulated model and the simulated improvement scenarios of the yogurt and mozzarella cheese line. Of the improvement scenarios proposed in the yogurt production line, the incorporation of 5 S is the best scenario because it reduces the cycle time to 620.3 min and productivity of 0.966 units / min. While in the mozzarella cheese production line, the scenario with the standardization of processes was the best with a reduction of the cycle time to 2185 min and a productivity of 0.450 units / min. In the yogurt production line, cycle time was reduced by 9.68% and productivity increased by 10.27%. While in the cheese making line, the cycle time was reduced by 6.58% and productivity increased by 6.79%. In the yogurt production line, the company obtains a daily income of $ 2700 from the sale of 2L yogurt, while with the improvement proposal it could increase production and generate sales of $ 2992, increasing income by 10 , 81%. While in the mozzarella cheese production line, daily income of around $ 375 is obtained from the sale of 250 g mozzarella cheese, and with the improvement proposal it could increase the income to $ 478, increasing the income around 27, 47%.Item Mejora de la productividad del área de pulido en la empresa Gusmar mediante la implementación de un sistema automatizado a bajo costo en la fabricación de calzado(Universidad Técnica de Ambato.
