Program for item-by-item sequential sampling by attributes

Abstract EN

This computet program, which is written in BASIC Language for an IBM-PC or compatible computer, generates solutions to sequential sampling problems.

Given the acceptable quality level, the producer's risk, the lot tolerance fraction defective and the consumer's risk.

the program produces all or one of the following: i ) Graphical representation of the plan (provided the computer has the color graphics capability).

ii) Table of acceptance and rejection numbers.

iii) Operational characteristic curve.

iv) Average sample number curve.

Furthermore, the program has a unique feature of calculating the values of probability of acceptance and average sample number for any value of proportion defective between acceptable quality level and lot tolerance fraction defective.
