DMAIC implementation on catalytic converter production line: a case study
| Summary: | This thesis presents the application of the DMAIC methodology to improve the production process of a production line of catalytic converters in an automotive components company. This production line has been reporting non-compliance with customer demands within the normal working hours. The study was based on the five phases of the DMAIC methodology: Define, Measure, Analyze, Improve and Control. In the Define phase, the problem was identified and the characterization of the project specifications and its objectives was carried out. The Measure phase focused on representing the problem in a quantifiable way through measurements of the initial conditions of the line. The third phase involved analyzing the measured data in order to identify the main problem and assign its root causes. For the Improve phase, appropriate solutions were selected for each identified root cause. In the Control stage, a Gantt Chart was developed for the planning and implementation of improvements, documentation, training and monitoring and to validate the improvements that had already been implemented in terms of eliminating or reducing the problem. The results of the project involve each tool applied at each stage of the DMAIC, but it is important to emphasize that it will support the company with the application of simple, fast and inexpensive solutions that acted on the elimination root causes of the problem. |
