| (54) | Improvements in or relating to computers for use in sampling procedures |
| (57) A computer is disclosed for use in sampling procedures for testing samples of a batch
of articles comprising a memory into which is entered one or more tables of data identifying
a sample code by batch size and inspection level. Also entered in the memory is a
file table of data representing a sampling plan identifying sample size and acceptance
and rejection parameters by the sample code and an acceptable quality level. The sample
code is identified by means for entering data representing the batch size and a predetermined
inspection level. Means is provided for entering data representing a predetermined
acceptable quality level and for utilising the identified sample code to identify
the corresponding sample size and acceptance and rejection parameters. A visual display
responds to the identified sample size to display this sample size. Means is provided
which responds to the identified acceptance and rejection parameters to derive and
store a value having a magnitude which is a function of such parameters. Means is
provided for entering into the computer sample data representing the acceptance and
rejection of each sample article tested and comparison means is provided to compare
the entered sample data with the derived and stored value to provide a first signal
representing batch acceptance or a second signal representing batch rejection. |
