Resumen
Este proyecto busca como meta la reducción de paradas no programadas en la línea de refinamiento de coberturas de chocolate de la empresa Gustaff. El método que se empleo fue la recolección de datos a través de los registros de producción y mantenimiento, donde se llegó a determinar a través del análisis de Pareto, las fallas que afectan en mayor magnitud y que incidieron a que existiera una utilidad no percibida de $99,090.77 y costos por reparaciones de $11,477.50 en el periodo de estudio. Para ello se propondrá una mejora basada en la estructura de dos de los pilares de la metodología TPM (Mantenimiento productivo total), que son el mantenimiento planeado, mantenimiento autónomo y la base de las 5”S”, cuyo costo de implementación es de $31,616.55, donde se considera un ahorro de $42,000.00 anual, con un valor actual neto de $50,210.17, una tasa interna de retorno del 37% y un costo-beneficio de $2.59, demostrando que la propuesta es factible y rentable.

The method used was the collection of data through the records of production and maintenance, where it was determined through the Pareto analysis, faults affecting in greater magnitude, and impacted on a not perceived utility of $ 99,090.77 and costs for repairs of $11,477.50 in the period of study. To this, there will be proposed an improvement based on the structure of two pillars of the methodology of TPM (total productive maintenance), which are the planned maintenance, autonomous maintenance and the basis of the 5 "s", the implementation cost is $31,616.55, which will be considered a savings of $42,000.00 annually, with a net present value of $50,210.17, an internal rate of return of 37% and a cost-benefit of $2.59 demonstrating that the proposal is feasible and cost-effective.
