Abstract
In this article, we have proposed runs rule-based control charts,namely, Improved Synthetic Control Chart’ (ISCC-x̄) and ‘Improved Group Runs Control Chart’(𝐼𝐺𝑅𝐶𝐶 −X̄) to detect shift in the process mean of a univariate production process. In zero state and also in steady state, it is numerically illustrated that 𝐼𝑆𝐶𝐶 −X̄ and 𝐼𝐺𝑅𝐶𝐶 −X̄ perform significantly better as compared to the related charts.
