AOQ {LTPDvar}

Average outgoing quality

Description

Average outgoing quality is the mean fraction defective after inspection when the fraction defective before inspection was p, lot size is N and plan (n,k) is used for sampling inspection. The average outgoing quality (assuming that all defective items found are replaced by good ones) is approximately

AOQ(p)=\left(1-\frac{n}N\right)\!\cdot p\cdot\!L(p;n,c).

Usage

AOQ(p,n,k,N, type=c("exact", "napprox","ewmaSK","ewma2"),lam=1)

Arguments

p

fraction defective before inspection

n

k

critical value

N

lot size (number of items in the lot)

type

type of operating characteristic, see OC, default value "exact"

lam

smoothing parameter for the EWMA statistic, default 1

Value
