Abstract:
The Automotive and Automotive Parts Industry in Thailand is facing increased business competition. Eliminating waste in the production process is essential for enhancing efficiency and competitiveness. This research aims to study the application of lean concepts to improve production efficiency. The data was collected from a sample group of 100 participants from production manager, supervisor, and staff. The questionnaire was used as a research tool and the statistical query used, including the frequency, percentage, mean, standard deviation, t - test, ANOVA.
The results showed indicate that the importance regarding the application of lean concepts to enhance production efficiency classified by overall is high level ( x̅ =4.36). By classified are the eliminating waste in the process (MUDA) is high level ( x̅ =4.44), the eliminating overburden in the system (MURI) is high level ( x̅ =4.35), and eliminating variability in the process (MURA) is high ( x̅ =4.30). The results of comparison of mean differences regarding the importance of lean concepts to enhance production efficiency, based on registration methods and business operation duration, show statistically significant differences at the 0.05 level.
