Reducción del tiempo de ciclo de instalación de dispositivos tecnológicos en vehículos

Abstract

The objective of this project is to reduce the cycle time of the technological device installation service in vehicles, due to high levels of variability and the failure to meet the standard time of 160 minutes, which negatively affect operational efficiency and customer satisfaction. The hypothesis is that optimizing the process flow through improvements in layout, intake control, and digital traceability can significantly reduce the total installation time and its variability. The study is justified by the need to enhance the company’s operational performance and competitiveness. For the project development, the DMAIC methodology was applied. Process analysis tools, simulation in FlexSim, layout redesign, design of a service pull system, development of a traceability application, and statistical techniques such as normality analysis, paired t-test, and process capability analysis were used. The results showed a reduction in the mean cycle time from 168.79 minutes to 104.79 minutes, a statistically significant improvement, and an increase in economic, social, and environmental indicators associated with productivity. It is concluded that integrating flow improvements, operational control, and digitalization allows for establishing a more efficient, stable, and sustainable process over time.
