Acceptance Sampling Plans for Export Quality Manufacturing having Weibull Lifetimes
D. P. Raykundaliya , Christian Sanjay , Divecha Jyoti
Abstract
In this paper, we develop zero modified binomial-Weibull life test sampling plan (ZMBWLSP) suitable for acceptance/ rejection of lots with export quality constraint. For economical plans, we make use of the historical information and design it based on Exponential Weighted Moving Average (EWMA) statistic and Modified Exponential Weighted Moving Average (MEWMA) statistic. Ready to use tables of optimum sample size and acceptance number for various quality and shape parameters are given for lots to have specified 50th sample quantile (median life) whose every item has a lifetime greater than the 10th quantile time. The 10th quantile time truncated ZMBWLSPs are demonstrated through two real-life examples. R codes are provided in the appendix for self-construction of the plans as per the users’ choice.
