Abstract
This paper deals with the optimal designing of a two-stage chain sampling plan of type ChSP (0,2) by considering the double sampling plan as the reference plan indexed through Acceptable Quality Level (AQL), Limiting Quality Level (LQL), Indifference Quality Level (IQL) and its operating ratio. Poisson unity values have been tabulated to facilitate the operation and construction of the plan. The tables are constructed by considering the various combinations of acceptable and limiting quality levels.
