Acceptance Sampling Software
New: Version 3 of TP105 & TP414 for Windows

visitors=Hit Counter

The goal -- to prevent the use of existing materials, products, processes, and services of off-grade quality. (Glossary)

The software develops acceptance sampling plans based on their operating characteristic curves.

These programs perform the statistical calculations for the sample size and decision rules of acceptance sampling plans. They use the two-point method , in which you specify two points of the operating characteristic curve. (OC-Curve)

See the tutorial for a detailed description of the operating characteristic curve.

Typical Uses: The most frequent applications of this software involves the design of decision rules for accepting and rejecting material and processes related to manufacturing, engineering, and laboratory. For manufacturing applications, the plans are used for incoming, in-process, and outgoing materials.

Two-Point Method: These three programs develop acceptance sampling plans by the two-point method. They design decision rules which consist of the sample size and acceptance limit(s). When you specify two points on the Operating Characteristic (OC) Curve, the program determines the decision rule which satisfies that curve. Thus the terms: two-point method. It allows you to assure that acceptance decisions meet the probabilities or risks that you choose.

Reverse of the Two-Point Method: In the reverse procedure, you specify a decision rule and the program calculates its OC-Curve. This feature allows you to use a "trial and error" approach, and to analyze existing sampling plans to determine the level of protection that they provide.

Sequential Sampling Plans: These programs will also develop sequential sampling plans by the two-point method. A sequential decision rule can be developed to match the OC-Curve of any fixed sample size decision rule.

Performance Curves: These programs will list and plot the OC, AOQ, ASN, and ARL curves of any decision rule.

Statistically Based: These three programs use both the Consumer's Risk and the Producer's Risk.
