Aumento de la eficiencia de una línea de ensamble de baterías para vehículos

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The objective of this project is to increase the average efficiency of assembly line 3 of a vehicle battery manufacturing company, using Lean Six Sigma tools such as the DMAIC (Define, Measure, Analyze, Improve, Control) methodology. This work was carried out in conjunction with the line personnel, operators, supervisors, mechanics and managers, who provided key and valuable information. Statistical analysis and observations were made in the area in order to find the root causes of each minor stoppage. Due to the large number of battery references that are assembled on line 3 per day, there is a great loss of efficiency during each reference change and calibrations before starting production. Thanks to DMAIC's work in stages, solutions were proposed for each root cause and it was possible to reduce the times of minor stops, changeover times and calibrations in the line, which had a direct relationship with efficiency. Once these solutions were implemented, the average efficiency increased from 64% to 71%, at the same time reducing line waste such as non-conforming batteries. Keywords: DMAIC, references, efficiency.
