Figure 1. Operating Characteristic curves and Average Sample Number for LQAS and MC-LQAS.

A) Operating Characteristic curve for LQAS design with n = 15,d = 7, and α = β = 0.20; B) Operating Characteristic curves for low (dashed-dotted), medium (dashed), and high (solid) categories for MC-LQAS design with n = 15, d₁ = 1, d₂ = 7, and δ₁ = δ₁ = δ₁ = δ₁ = 0.20; C) Average Sample Number for semi-curtailed (solid) and curtailed (dashed) LQAS with n = 15 and d = 7; D) Average Sample Number for semi-curtailed (solid) and curtailed (dashed) MC-LQAS with n = 15, d₁ = 1, and d₂ = 7.
