    Estudio de puestos de trabajo en el área de poscosecha, para optimizar tiempos de producción en la empresa Agrogana
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-07) Villavicencio Toro, Andrés Marcelo; López Velástegui, Jorge Enrique
    This study analyzes the jobs in the post-harvest area, to optimize production times in the AGROGANA company, where to carry out this activity, it begins with the recognition of the production process within the post-harvest area, which They are divided into mallero, classifier, packer, cut, finished, classified in the cold room, separated, fingered, packed and shipped. The study was carried out in each work area, with an analysis of the activities carried out and the taking of times by means of a stopwatch, subsequently proceeding to determine the critical path, continuing with the selection of alternatives, defining their routes and minimum times to delay, resulting in a solution that minimizes the critical path defined above. Finally, it is proposed to carry out a standardization of times and movements, taking into account the critical routes in each alternative, thus reducing unnecessary times and existing delays in the execution of the activities that make up the same.

    Desarrollo de un plan de mantenimiento en el subproceso de molienda en La Industria Harinera S. A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2020-09) Chiguano Allauca, Wilmer Wladimir; López Velástegui, Jorge Enrique
    The purpose of this technical project was to introduce the philosophy of TPM (Total Productive Maintenance) in the company La Industria Harinera SA, for which, 11 of the 12 necessary steps were carried out that are established by the JIMP (Japanese Institute of Plant Maintenance ) in the milling sub-process, which is the most critical of the whole flour-making process. This project established all the necessary parameters for the functional implementation of the philosophy, which are presented in a master plan for the 5 S, autonomous maintenance, planned maintenance, predictive maintenance and quality maintenance. This allowed them to be applied in the other sub-processes that the company owns, in the future if senior management so has it. The activities proposed for the planned maintenance in the B1 grinding bench were proposed based on the calculation of the maintenance indicators MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repairs), these provided important data to perform the OEE calculation. (Global Effectiveness of Equipment) and thus allowed to make maintenance decisions that improve the performance of the equipment and the activities proposed for predictive maintenance, was based on recognizing with the TPM group the best predictive method that fits the parameters of the machine to be carried out maintenance. In each of the planned maintenance processes, standardization and audits were imposed to control and be able to carry out the continuous improvement method in a more efficient way.
