    Modelo de gestión por procesos para la mejora operativa en la empresa calzado “Liwi Medical”.
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2025-02) Arias Cox Jaime Antonio; Ortiz Sailema Christian Ismael
    This research presents a process management proposal for Liwi Medical Footwear company, aimed at structuring and documenting its operational processes. The methodology encompassed an initial diagnosis through interviews and surveys, followed by process identification and classification utilizing process mapping and value chain analysis. The weighted factors method was employed for critical process selection, enabling the prioritization of those with the highest organizational impact. The study resulted in comprehensive documentation of operational processes, including process sheets, flowcharts, management indicators, and a process and procedures manual. This documentation provides a structured foundation for the potential implementation of a process management system, establishing metrics for operational evaluation and continuous improvement. The proposal developed constitutes a strategic asset for Liwi Medical Footwear, offering a systematic view of its operations and establishing the groundwork for future improvement initiatives. The designed model maintains the necessary flexibility to adapt to organizational changes, allowing updates as the company's needs evolve.

    Optimización de Los procesos operativos mediante la teoría de restricciones en empresas metalmecánicas
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Producción y Operaciones Industriales, 2021) Espín Guerrero, Ricardo David; Ortiz Sailema, Christian Ismael
    The research is about the operational processes optimization using the theory of constraints in the metal-mechanical Maquinarias Espín. Initially, delays and bottlenecks were detected in the production of wood processing machines, these aspects forced the extension of the working day. The production of the seven machines with the highest demand was considered, taking into account the information of the average monthly quantity required according to the orders of the last two years. A time study was carried out and the available resources were evaluated to quantify the use of the workstations. Two constraints were identified in hand saw cutting and turning as part of the application of the theory of constraints, with utilization ercentages of 111.82% and 105.11%, which implied an inability to meet the average monthly demand. From exploiting the constraints based on the application of the PLE to maximize the return and once everything was subordinated to them, the maximum possible monthly return was determined to be $78470, with a maximum net profit of $68362.68. However, the maximized production volume did not meet the average monthly demand, with a shortfall of 5% of circular saws and 75% of band saws. A CNC plasma cutting machine was added as well as the distribution of workers at the workstations was rearranged. It was determined that there were no longer any constraints once the actions were implemented, but the PLE was again applied to optimize production based on the available resources. These actions allowed obtaining a maximum yield of $ 87768.74, with an optimal monthly gross profit of $ 77188.10, an increase of 12.91% of the gross profit from the sale of the machines, having covered the production capacity required by the demand.
