Question: Discuss how you could set up one sided EWMA control charts
Discuss how you could set up one-sided EWMA control charts.
Answer to relevant QuestionsRework Exercise 9.4 using the standardized CUSUM parameters of h = 8.01 and k = 0.25. Compare the results with those obtained previously in Exercise 9.4. What can you say about the theoretical performance of those two CUSUM ...Use the data in Table 10E.1 to set up short-run charts using the DNOM approach. The nominal and x R dimensions for each part are TA = 100, TB = 60, TC = 75, and TD = 50. The data in Table 10E.8 are molecular weight measurements made every two hours on a polymer (read down, then across from left to right). (a) Calculate the sample autocorrelation function and provide an interpretation. (b) ...Set up a moving center line EWMA control chart for the concentration data in Exercise 10.20. Compare it to the residuals control chart in Exercise 10.20, part (c). To find the optimal , fit an ARIMA (0,1,1) (= EWMA = ...An x chart is used to maintain current control of a process. The cost parameters are a1 = $0.50, a2 = $0.10, a3 = $25, a′3 = $50, and a4 = $100. A single assignable cause of magnitude δ = 2 occurs, and the duration of the ...
