For enhancement of mean monitoring power of the exponentially weighted moving average (EWMA) chart, a new median quartile double ranked set sampling (MQDRSS) based EWMA control chart is proposed and named as EWMA-MQDRSS chart. In order to study the performance of the developed EWMA-MQDRSS chart, performance measures; average run length, and the standard deviation of run length are used. The shift detection ability of the proposed chart has been compared with counterparts, under the simple random sampling and ranking based sampling techniques. The extensive simulation-based results indicate that the EWMA-MQDRSS chart performs better to trace all kinds of shifts than the existing charts. An illustrative application concerning monitoring the diameter of the piston ring of a machine is also provided to demonstrate the practical utilization of the suggested chart.

The proposed estimators are based on the information from two transformed auxiliary variables using simple random sampling without replacement. The expression for the mean square error and bias of the proposed estimators has been derived, and the conditions have been obtained under which these estimators are more efficient than the existing estimators. Empirical study has also been conducted to show the improvement in efficiency of the proposed estimators.

The class of ratio (including chain ratio) and regression estimators are further explored and expanded. Comparisons with other estimators suggested in the literature are also made.
