المستخلص: 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 (σˆ) estimator in the Process Capability Indices to justify the efficiency. Concluded that in this study, Downton estimator have better property than the other (σˆ) estimator because that the process Capability Indices values based on Downton estimator greater than the process Capability Indices values based on (σˆ) 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 (σˆ) estimator.
