Beschreibung:
<p>In the present work, a process control plan based on two-sided gauging in a situation where the process average is liable to shift on either side of the aimed at value and the process variability is assumed to be controlled at a known level, has been developed by carrying out a sensitivity analysis on the performance indices of the plan with respect to the decision variables. The plan parameters (gauge-limits ond control limits) have been numerically obtained for n = 2(1)10, α = .005, .01, .025 and .05 assuming a normal model. A curtailed inverse sampling scheme has been suggested for the operation. The efficiency of the plan has been compared with that of the traditional X̄-chart.</p>
