Incremento del porcentaje de rendimiento de carne de pescado en una planta procesadora de atún

Abstract

CONDITION FOR PUBLICATION OF PROJECT. This project is developed in a tuna processing company located in Guayaquil, focusing on the critical fish cleaning process where significant losses of light meat are observed. The objective is to increase the tuna light meat recovery percentage from 47.7% to 48.35% through the DMAIC methodology, justified by its impact on economic profitability, environmental sustainability, and operational efficiency. For the project development, data collection was conducted over seven months in the cleaning line. Statistical tools were applied such as Anderson-Darling test for normality, capability analysis with Weibull distribution, I-MR control charts, ANOVA for variability among operators, and linear regression. Three root causes were identified and corresponding solutions were implemented: structured training program, replenishment time optimization through FlexSim simulation, and digital Kanban system for FIFO control. The results showed a statistically significant increase in recovery from 47.09% to 48.40%, improving the process capability index from 0.32 to 1.04. Labor absenteeism was reduced from 10% to 6% and waste generation from 30% to 25%. Keywords: DMAIC, Lean Manufacturing, Six Sigma, process capability, operational efficiency.
