Group acceptance sampling plan based on truncated life tests using extended odd Weibull exponential distribution with application to the mortality rate of COVID-19 patients

Abstract

This study examines group acceptance sampling plans for many items evaluated together, with the product lifetime following the extended odd Weibull exponential (EOWEx) distribution. Significant design parameters are derived when the consumer risk and the test termination period have been established. Different quality levels are used to define the values of the operational characteristic function. The minimum ratios of the specified average life to the real average life are also computed at the risk of the designated producer. The results of this study provide a foundation for future research on a wide variety of situations at the micro-quality level, where the items follow varied probability distributions under the extended odd Weibull exponential scheme. The mortality rate of COVID-19 patients in the UK is used to display the group acceptance sampling plan for the EOWEx distribution. The performance of the presented sampling plan is compared to the ordinary sampling plan when the quality of the product follows the EOWEx distribution.
