Abstract

Acceptance Sampling plans are the practical tools for quality assurance applications involving product quality control. Using Trigonometric ratio, one can get a better plan which has an OC curve similar to ideal OC curve. The approach of trigonometric ratio method by considering the tangent of the angle between the lines joining the points (AQL, 1 -α)(LQL,β ). This paper introduces a procedure and tables for the selection of Three Stage Chain Sampling Plan (0, 1, 2) with Repetitive group sampling plan using Trigonometric ratio, involving producers and Consumers quality levels. A table and methods are given for the construction of plans indexed by using trigonometric ratio.

Keywords and Phrases

Acceptable Quality Level, Indifference Quality Level, Limiting Quality Level and Three Stage Chain Sampling Plan, Minimum Angle method, Repetitive Group Sampling plan.
