AOQ: Average outgoing quality

In LTPDvar: LTPD and AOQL Plans for Acceptance Sampling Inspection by Variables

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)=≤ft(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	sample size
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

single value
