This study analyzes the performance of a combined Shewhart-EWMA control chart based on double median ranked set sampling (DMRSS), for efficient monitoring of changes in process mean level. The numerical performances of the proposed scheme were evaluated in terms of the average run length (ARL), standard deviation of run length, the average ratio ARL and average extra quadratic loss. Results show that the use of a well-structured sampling method on the combined scheme has greatly enhanced the performance of the scheme in detecting all kinds of shifts in a process. We present a comparison of the proposed scheme with some location charts for monitoring changes in a process. Practical application of the proposed scheme is also demonstrated using real industrial data.
