Abstract

In the management of suppliers, it is an important task to compare the performance of two suppliers using the linear profiles. In this paper, the product acceptance determination procedure is designed using a EWMA statistic based on the process-yield index applied to the linear profiles of two suppliers. The design parameters of the proposed plan are determined to satisfy both the producer’s and consumer’s risks. The efficiency of the proposed sampling plan is compared with the sampling plan developed based on the Wang’s test statistic in terms of the sample size required for the selection of a better supplier. A real example is given to explain the proposed sampling plan.
