Enhancement of On-time Delivery Maintenance Services by Lean Manufacturing Tools in an Automotive Industry

In recent years, the automotive industry has continued to develop exponentially. However, this has led to an increase in the demand for maintenance services that automotive repair companies are unable to provide (representing significant losses for automotive companies). Thus, to maximize the number of maintenance services performed each day and reduced the costs associated with penalties, automotive repair companies try to optimize maintenance service hours. According to the current analysis, the main problem that causes the greatest financial loss in a Peruvian auto repair company is the high percentage of maintenance services that are not performed. The company considers the issue to be crucial not only for the economy but also for the connection it maintains with its customers, as they are very likely to choose to travel to other auto repair centers if there are delays in deliveries. The company's assistance and data collection made it possible to identify the main causes of these delays. As a result, it is proposed to create a model based on the Lean Manufacturing technique, using the 5S tool, ABC analysis and standardized work, with the aim of optimizing the delivery times of the company's existing vehicle repair service. In the end, the approach reduced delivery time violations by 19.94%. In conclusion, the company was able to satisfy its customers and avoid delays as a result of the improvement made.
