Evaluation of Two Process Yields in Acceptance Sampling Plans

Abstract

Competitive activities always support improvement in quality. In this study, a repetitive group sampling plan is designed to compare the two process yield indices of respective suppliers. A ratio statistic of two yield indices is proposed for estimated linear profiles under normal assumptions. The operating characteristic function is derived by using the distribution of the ratio statistic. Designed parameters are optimized to minimize the sample size required.

Product Acceptance Determination by Two Suppliers with Linear Profiles

“…Aslam et al [22] designed a sampling plan using EWMA statistic when quality of interest follows the normal distribution. More details on the applications of the sampling plans can be seen in [23][24][25][26][27][28][29][30][31][32]. Also, some of the sampling plans have been developed based on EWMA statistic (see for example [33][34][35][36][37][38][39][40][41][42][43].…”

Design of a New Synthetic Acceptance Sampling Plan

“…Aslam et al [13] proposed a mixed repetitive sampling plan using a process capability index. Butt et al [14] proposed the plan for the process yield. Balamurali et al [15] designed a mixed variable plan using the process capability index.…”
