Reconsider the data in Exercise 9.4. Suppose the data there represent observations taken immediately after a process adjustment that was intended to reset the process to a target of µ0 = 8.00. Set up and apply an FIR CUSUM to monitor this process.
Answer to relevant QuestionsThe data in Table 9E.3 are temperature readings from a chemical process in C, taken every two minutes. (Read the observations down, from left.) The target value for the mean is 0 = 950. (a) Estimate the process ...Consider a modified control chart with center line at µ = 0 and σ = 1.0 (known). If n = 5, the tolerable fraction nonconforming = 0.00135, and the control limits are at three-sigma, sketch the OC curve for the chart. ...Consider the molecular weight data in Exercise 10.16. Construct a EWMA control chart on the residuals from the model you fit to the data in part (c) of that exercise. Let = 0.1 and L = 2.7 (approximately the same as a ...Consider the temperature data in exercise 10.24. Set up a CUSUM control chart on the residuals from the model you fit to the data in part (c) of that exercise. Compare it to the individuals chart you constructed using the ...An x chart is used to maintain current control of a process. The cost parameters are a1 = $2, a2 = $0.50, a3 = $50, a′3 = $75, and a4 = $200. A single assignable cause of magnitude δ = 1 occurs, and the duration of the ...
