Mejora del proceso de elaboración de alimentos para Broilers mediante la implementación del proceso de negocio Seis Sigma-DMAIC, en una planta de producción de alimentos balanceados

Abstract

Six Sigma and its DMAIC methodology was applied to achieve improvements in the manufacture of broiler feed. A review was performed, identification and sequencing of all processes. In the Definition phase and based on farm claims, dosing-bins (DB), dosing-oil (DA) and mixing quality (CM) were defined as the key processes. In the Measurement phase, the calculation of the process capacity (Cp) of the DB and DA processes and the coefficient of variation (% cv) and mixing time. For CM was performed. In the Analysis phase, a hypothesis test for DB, correlation test and ANOVA for DA and% cv tests for CM were performed. In the Implementation and Control phases, an improvement was found in the Cp indices (DB from 0.75 to 0.9; DA from 0.18 to 2.2), sigma level (DB from 1.97 to 2.4 ; DA from 0.58 to 6) and cv (9.39% with 210 sec. to 9.32% with 180 sec). Finally, the improvement of the methodology was evaluated with the cycle time and productivity, these decreased from 14.14 to 2.06 minutes and daily productivity improved 0.001037 batch / $ to 0.001038 batch / $.
