Determination of product acceptance for two suppliers with linear profiles

Abstract

In the supplier management, it is necessary to compare the performances of two suppliers using linear profiles. In this study, the determination procedure for product acceptance was designed using the Exponentially Weighted Moving Average (EWMA) statistic based on the process-yield index applied to the linear profiles of two suppliers. The design parameters of the proposed plan were also determined to satisfy both the producer's and consumer's risks. The efficiency of the proposed sampling plan was compared to that of the sampling plan developed based on Wang's test statistic in terms of the sample size required for selecting a better supplier. To this end, a real example was presented to explain the proposed sampling plan. ? 2021 Sharif University of Technology. All rights reserved.
