| dc.description.abstract | The rise of lean manufacturing has led to both opportunities and challenges for all types
of companies, requiring companies and logistics providers to invest lean processes into
their production systems. In recent years, many manufacturing companies have used a
integration of Lean and Six Sigma as tools, techniques and principles to address waste
in the manufacturing process. This study is dedicated to investigating the problems in
which the case study company maintains the output quality of finished wood products
and addresses the difficulties in which the factory is not operating, leading to a decrease
in output manufacture. Using the DMAIC and Overall Equipment Effectiveness (OEE)
methods, the article uses quality management methods to evaluate and measure the
performance and capabilities of machines in the company's line. After using Fishbone
and FMEA tools, the root causes of product delays and quality loss were identified,
specifically defects in wood such as shake, knot and wane. The company has made
efforts to improve performance and achieved positive results such as increasing the
sigma level from 3.2 to 3.53, the defect rate has exceeded the company's previously set
target of 2.1%. In addition, the article determined that downtime was not part of the
production plan when production was taking place and was beyond the factory's ability
to predict, causing the line's operating capacity to decrease, and at the same time reduced
ability to meet customer needs. | en_US |
