Construction of AOQ curve and calculate AOQL value based on limiting fraction

Description

AOQL_grab_A provides the AOQ curve and calculates AOQL value based on limiting fraction of contaminated increments.

Usage

AOQL_grab_A(c, r, t, d, N, method, plim)

Arguments

c	acceptance number
r	nurber of primary increments in a grab sample or grab sample size
t	number of grab samples
d	serial correlation of contamination between the primary increments
N	length of the production
method	what sampling method we have applied such as 'systematic' or 'random' selection methods
plim	the upper limit for graphing the fraction nonconforming or proportion of contaminated increments

Details

Since P_{ND} is the probability of non-detection, p is the limiting fraction of contaminated increments and the outgoing contaminated proportion of primary increments is given by AOQ as the product pP_{ND}. The quantity AOQL is defined as the maximum proportion of outgoing contaminated primary increments and is given by

AOQL ={\max_{0\leq p\leq 1}}{pP_{ND}}

Value

AOQ curve and AOQL value based on on limiting fraction
