    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.

    Desarrollo de un plan de mantenimiento preventivo para la maquinaria de la línea de producción de la empresa Welding & Vayacons CIA. Ltda. aplicando el método de mantenimiento productivo total (TPM)
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-02) Barrera Delgado, Welington Amilcar; López Velástegui, Jorge Enrique
    This present technical project appears as a response to a lack of maintenance planning in the Welding & Vayacons CIA LTDA Company. It has the purpose to implement the TPM philosophy (Total Productive Maintenance) which is going to generate annual maintenance planning for the machines and equipment that exist inside the company. The maintenance planning is based on the 5S application and autonomous planned maintenance as well. The technical project established all the necessary forms to develop the maintenance activities such as technical sheets, criticality analysis, machines inspections, and other services for the correct maintenance. The proposed activities within the maintenance annual planning for each machine are the manual functions, visual analysis, equipment background, quantitative criticality analysis, and the well-known failures and effects modal AMFE analysis. This data allows us to obtain the critical values of the components. All the activities are reflected in the annual preventive maintenance planning. These activities aim look for to ensure correct and optimal use of the machines and equipment in order to prolong their useful life and reduce downtime. Within the researching there was the intervention machines and the company facilities as well to acquire tidy and clean facilities to improve the working environment. Thanks to all these activities look for business growth in the oil services field.
