Determination Of Quick Switching System-Ss (Two Single Sampling Plans) Using Poisson Distribution

Abstract

Quick Switching Systems (QSS) are generally employed in making acceptance/rejection decisions during inspection process of any manufactured product. Based on the past results, the number of units and the acceptance criteria may be varied in QSS hence provide additional protection during poor quality time and reduction in inspection cost during good quality time. This article focuses on protection provided by QSS-SS (two single sampling plans) using Poisson distribution during the time of constant and changing quality. QSS-SS are compared with Single Sampling Plan, Double Sampling Plan and Quick Switching System where QSS -S, where QSS-SS was given by Taylor in the year 1992 and showed the efficiency with QSS (Romboski).
