PICHET KAEWSAITHOM : THE APPLICATIONS OF RELIABILITY BASED MAINTENANCE FOR REDUCING DOWNTIME IN THE SAMPLE PAPER FACTORY.
THESIS ADVISOR : ASST.PROF.PRACHUAB KLOMJIT, D.Eng., 165 pp.
The objective of this study aimed to reduce downtime because of machine breakdown and to schedule the preventive maintenance plan based on the reliability based maintenance theory for the machine components of a case study. The research methodology include procedure as following the priority of critical components in the paper machine, analysis the root cause and failure mode by using failure mode and effect analysis (FMEA), simulating the failure patterns of component parts from historical data, calculating the suitable reliability parameters and scheduling the preventive maintenance interval and optimization. The result of this study can be concluded that the downtime loss because of breakdown in MC1, MC2, and MC3 can be decreased in 2,196 minutes/month, 4,025 minutes/month, and 1,929 minutes/ month or failure rate can be reduced 5.68%, 10.04%, and 4.94% accordingly. Moreover the machine availability has been increased in 80.20%, 80.02%, and 81.00% respectively. The statistical test was selected to review and analyze the result of study that it reaches to significant level at 0.05 for all 3 machines which P-Value less than the significant level (P < α).
