Overall equipment efficiency

*Overall equipment efficiency” is used as an indicator of how well equipment is used in batch/lot production.

The overall equipment efficiency is obtained in relation to losses that can impede equipment efficiency. The magnitude of stoppage loss is expressed as availability, that of performance loss as performance rate, and that of defect loss as quality products rate ratio. The product of the three ratios is called “overall equipment efficiency.” Overall equipment efficiency = Availability Í performance rate Í quality products rate.

Empirically, the targets have been 90% or higher in the case of availability, 95% or higher in the case of performance rate, and 99% or higher in the case of quality products rate. The overall equipment efficiency has been targeted at 85% or higher.

Generally the overall equipment efficiency of a plant before introduction of TPM ranges between 40% – 60%.When this ratio is raised to 85% or more. A 1.5 – 2-fold production increase can be attained with the existing facilities. Or if, output is kept constant, production is possible with only 1/2 -2/3 of the present equipment

Seven major losses that can equipment effectiveness

In TPM, 16 major losses are addressed as problems hampering production system effectiveness. Of these, the following seven losses are addressed as the ones that impede equipment effectiveness:

  • Failure losses
  • Set-up/adjustment losses
  • Cutting blade change losses
  • Start-up losses
  • Minor stoppage/idling losses
  • Speed loss
  • Defect and rework losses
  • Reference →16 major losses

Sixteen major losses

In TPM, every effort is made to maximize production system effective and explore to keep all losses hampering such effectiveness to zero. These are 16 losses that hamper production system effectiveness hence they are called “16 major losses that hamper effectiveness.

Seven major losses that can hamper equipment effectiveness

  • Failure losses
  • Set-up/adjustment losses
  • Cutting blade change losses
  • Start-up losses
  • Minor stoppage/idling losses
  • Speed losses
  • Defect and rework losses

Losses than can impede machine operability:

  • SD (Shutdown) losses

Five major losses than can impede man’s efficiency:

  • Management losses
  • Motion losses
  • Arrangement losses
  • Losses resulting from lack of automated systems
  • Monitoring and adjustment losses
