Guide to Acceptance Sampling - PDF File

Description

ISBN 0-9635122-0-X – Electronic Format only (PDF file)
By: Dr. Wayne A. Taylor

Book Objective

This book shows how to reduce costs and improve the effectiveness of acceptance sampling in a manufacturing setting. It also serves as a basic introduction to acceptance sampling. The book is intended for the practitioner. It avoids complex mathematical formulas. Instead, extensive tables and powerful software are provided.

This book focuses on the core methods that are in common use. It also covers such practical issues as how to select samples, form inspection lots, and where to place inspections. Further, the role of acceptance sampling in today’s modern world is explored in detail.

Intended Audience

This book is designed for those individuals who select sampling plans and set sampling policy. This includes engineers, manufacturing and quality supervisors, and management.

No statistical background is required. As such, the text serves as an excellent introduction to acceptance sampling. It also includes important new material of interest to the expert including quick switching systems.

Comprehensive Tables

This book includes comprehensive tables of single sampling plans, double sampling plans, quick switching systems, and variable sampling plans all indexed using a common system. This makes it easy to select alternative double sampling plans, quick switching systems and variable sampling plans.

Accompanying Software

This book comes with a comprehensive set of DOS programs for selecting and evaluating different types of sampling plans. For those in the medical device and FDA regulated industries, this software is validated. These programs, while still available, have been replaced with the Windows program Sampling Plan Analyzer, sold as a separate product.

Important Advance

This book introduces an important new method called quick switching systems. Quick switching systems can reduce sampling costs by as much as 85% or provide equally dramatic improvements in protection. They also serve as a valuable tool for monitoring processes. Quick switching systems replace chain sampling plans and the switching system in Mil-Std-105E.

Software

The six DOS programs accompanying the book are for individuals purchasing the book Guide to Acceptance Sampling and the book serves as the user manual. Appendix A of the book provides full details on the programs. These programs, while still available, have been replaced with the Windows program Sampling Plan Analyzer, sold as a separate product.

Capabilities

The software consists of six programs that have the following capabilities:

Types of Sampling Plans:
- Attribute single sampling plans
- Attribute double sampling plans
- Quick switching systems
- Variables sampling plans with known and unknown standard deviations and both 1 or 2 specification limits.
Evaluates sampling plans including:
- OC curves
- AOQ curves
- ASN curves
- Percentiles (AQL, LTPD, RQL, LQ, UQL)
- AOQL
- ASN curves
Selects plans based on:
- AQL and LTPD
- AQL and AOQL
- AQL and sample size
- Economics

Validation Package

The software has been validated as required by the FDA for use in the pharmaceutical, medical device and diagnostic industries. A copy of this validation package can be downloaded below.

Requirements

The six programs run on a PC under DOS. They can be run in the DOS compatibility box under Windows 3.1, 95, 98, 2000, NT, XP, Vista, 7, 8 and 10. The current Version 1.2 are 32-bit programs that runs on 32-bit and 64-bit machines.
