Abstract
Statistical quality control relies heavily on the goodness of control chart limits. The more accurate those limits are, the more likely are to detect whether a process is in control. Various procedures have been developed to compute good control limits. This paper proposes variable control charts based on the percentiles of Exponentiated Lomax distribution (ELD) for mean, range and standard deviation. The percentiles of the distribution of mean, range and standard distribution were developed and are used to construct the control limits. The coverage probability of the control charts of ELD was compared with that of traditional shewhart control chart. The result shows that ELD performs better than the traditional shewhart control chart.
