Abstract :
This paper presents the graphical evaluation and review technique (GERT) exploration of performance measures for lot
acceptance sampling procedures having attribute characteristics following life tests based on percentiles of Rayleigh Distribution and
henceforth determining optimum sampling size. The advantageous implications of GERT analysis in this framework is primarily to
visualize the dynamics of the sampling inspection system and secondly, critical analysis of sampling procedure characteristics. The
formula of operating characteristics (OC) function and average sample number (ASN) function is derived and illustrated numerically.
Lastly, tables have been provided to determine the optimum sample size assuring certain mean life or quality of the product
