Abstract:
The purpose of this research was to enhance the efficiency of the filing Sanitary Wear
Clean Liquid line in the chemical manufacturer factory due to the broken machine and the
lack of well maintenance management problems. After the problems were analyzed, it was
found that there were two causes of problems. The first cause was the inefficient productive
maintenance management which were lack of the standard and the appropriate machinery
maintenance control effected the defective machine in the production line. The second cause
was the inefficiency of machine resulted from the background of machinery which were old
and lack of well maintenance as well as the chemical faced.
The data was collected to analyze the causes of the machine failure and found out the
solutions. Then the machine was repaired and the rate of loading time of machine was
increased. The sudden broken machinery was improved by using automatic maintenance
system. The productive maintenance system was set up by determining the detail of the
maintenance planning. The indicator index of this research were Overall Equipment
Effectiveness (OEE), Mean Time between Failure (MTBF) and Mean Time to Repair (MTTR).
After the implementation to improve the Overall Equipment Effectiveness of the Filing
Line machine, it appeared that the frequency of broken machinery was lower. The rate of
loading time of machine increased. The productive maintenance system was better. The
knowledge and skills of staff was higher. Therefore, the Overall Equipment Effectiveness
(OEE) of the product line increased from 73.70 % to be 84.10 %. The MTBF value increased
from 5670 minutes to be 7146 minutes or increased for 21.59 % and MTTR value decreased
from 14 minutes to be 11 minutes or decreased for 21.43 %.
