Functions

AOQ2 Function

computes average outgoing quality for a double-sampling plan.

Syntax

AOQ2(replacement,)

where

replacement

has the value 'REP' or 'NOREP', respectively, depending on whether nonconforming items are replaced with conforming items.

is the lot size, where .

is the acceptance number for the first sample, where .

is the rejection number for the first sample, where .

is the acceptance number for the second sample, where .

is the size of the first sample, where and .

is the size of the second sample, where and .

is the proportion of nonconforming items produced by the process, where .

Description

The AOQ2 function returns the average outgoing quality for a Type B double-sampling plan in which nonconforming items are replaced with conforming items (replacement is 'REP') or not replaced (replacement is 'NOREP'). For details on Type B double-sampling plans, see Types of Sampling Plans.

For replacement, the average outgoing quality is

     

and for no replacement, the average outgoing quality is

     

where, in both situations,

Examples

The first set of statements results in a value of 0.0148099904. The second set of statements results in a value of 0.0144743043.
