Mejoramiento de la eficiencia productiva del proceso de fabricación de confites aplicando la herramienta de calidad AMFE y el análisis centrado en la confiabilidad (RCM)

Abstract

The objective of this project was to improve the production efficiency of the confectionery manufacturing process through the application of the AMFE tool and an analysis focused on RCM reliability, the method allowed the calculation of indicators as the average time between failures and the average time to repair. Since the industry had variations affecting the production process, this was reflected in the high number of unscheduled stoppages, start delays, and low product quality index. According to reports in 2018, 1967.1 tonnes of hard candy was planned and actual production was 1826 tonnes, with 7.15% non-compliance. For this purpose, descriptive and analytical research, analysis of historical data, field observation was carried out with the purpose of making an analysis of the initial situation. According to AMFE, most unscheduled unemployment was due to lack and poor practice of operational activities. Therefore, it was considered necessary to implement TPM based on 5S's, complemented by root cause analysis tools. The study optimised activity times through process analysis and proposed improvements to equipment. With the implementation of the improvements it went from a 17-hour MTBF, reflected in a 43.3% fault reduction. The data history showed that 297 unemployments were introduced in 2018 and in 2019 they were reduced to 180, where a 39% reduction was achieved. MTTR decreased from 3.62 hours to 2.69 hours. In addition, equipment availability increased each month from 79% to 90%. Overall line performance increased from 57% to 79% and production efficiency increased from 38.1% to 68.3%, translating as competitive.
