Abstract

Process capability is the long-term performance level of the process after it has been
brought under statistical control. In other words, process capability is the range over
which the natural variation of the process occurs as determined by the system of
common causes.
Robust estimator is an estimator which is insensitive to changes in the underlying
distribution and also resistant against the presence of outliers.
In this paper proposes the using Downton estimator in the process capability indices
and compare with (ˆ ) estimator in the Process Capability Indices to justify the
efficiency. Concluded that in this study, Downton estimator have better property than
the other   ˆ estimator because that the process Capability Indices values based
on Downton estimator greater than the process Capability Indices values based on
  ˆ estimator. We also found the process Capability Indices based on Downton
estimator can be used as an alternative instead of the process Capability Indices
values based on   ˆ estimator
