document: Computer program for calculating the p-value in testing process capability index C/sub pmk / Many process capability indices , including C/sub p / , C/sub pk / , and C/sub pm / , have been proposed to provide numerical measures on the process potential and performance . Combining the advantages of these indices , Pearn et al. -LRB- 1992 -RRB- introduced a new capability index called C/sub pmk / , which has been shown to be a useful capability index for processes with two-sided specification limits . In this paper , the authors implement the theory of a testing hypothesis using the natural estimator of C/sub pmk / , and provide an efficient Maple computer program to calculate the p-values . They also provide tables of the critical values for some commonly used capability requirements . Based on the test , they develop a simple step-by-step procedure for in-plant applications . The practitioners can use the proposed procedure to determine whether their process meets the preset capability requirement , and make reliable decisions
