AQLSchemes - Retrieving Acceptance Sampling Schemes
Functions are included for recalling AQL (Acceptable
Quality Level or Acceptance Quality Level) Based single,
double, and multiple attribute sampling plans from the Military
Standard (MIL-STD-105E) - American National Standards
Institute/American Society for Quality (ANSI/ASQ Z1.4) tables
and for retrieving variable sampling plans from Military
Standard (MIL-STD-414) - American National Standards
Institute/American Society for Quality (ANSI/ASQ Z1.9) tables.
The sources for these tables are listed in the URL: field. Also
included are functions for computing the OC (Operating
Characteristic) and ASN (Average Sample Number) coordinates for
the attribute plans it recalls, and functions for computing the
estimated proportion nonconforming and the maximum allowable
proportion nonconforming for variable sampling plans. The
MIL-STD AQL Sampling schemes were the most used and copied set
of standards in the world. They are intended to be used for
sampling a stream of lots, and were used in contract agreements
between supplier and customer companies. When the US military
dropped support of MIL-STD 105E and 414, The American National
Standards Institute (ANSI) and the International Standards
Organization (ISO) adopted the standard with few changes or no
changes to the central tables. This package is useful because
its computer implementation of these tables duplicates that
available in other commercial software and subscription online
calculators.
