Why losses occur?• Operation exceeds its standard timing • Non-value adding operation is performed• Machine is idle when it should have given the rated output• Machine and or man do not give the rated output• Additional time, money and energy than the specified norms

OEE – Overall Equipment Effectiveness
OEE = Availability X Performance X Quality
Availability = 77% Performance = 95% Quality = 92%
77% x 95% x 92%

Planned Maintenance• Recoding present status• Improve weakness.• Information system• Preventive maintenance• Predictive maintenance system

Quality Maintenance• Detect the defect after it has been produced
• Prevent defects from being produced in the first place
