9. LOSE CALCULATION Downtime losses Reduced speed losses
A = Availability; T = Operating time (P-D); P = Planned operating time; D = Downtime
Reduced speed losses
E = Performance efficiency; C = Theoretical cycle time; N = Processed amount (quantity)
Poor quality losses
R = rate of quality products; Q = nonconformitives
Equipment effectiveness
EE = equipment effectiveness; OEE = overall equipment effectiveness
