a

Summary Introduction

Interpretation:

An analytical expression for the OC curve as a function of p.

Concept Introduction:

Average Outgoing Quality curve is the curve that represents the quality of both the incoming as well as the outgoing material, assuming the hundred percnt inspections of rejected lots and also the inspected defective materials are either removed, revised or exchanged.

  $\text{AOP(p)}\text{=}\frac{{\text{P}}_{\text{d}}{\text{P}}_{\text{a}}\text{(N-n)}}{\text{N}}$

  ${\text{P}}_{\text{d}}$ = % defective in every lot in the series

  ${\text{P}}_{\text{a}}$ = Quality of incoming lots

N = lot size

n = sample size

b

Summary Introduction

Interpretation:

The value of p at which the AOQ curve is maximum
