Systems and methods for multidimensional dynamic part average testing

An apparatus for performing dynamic parts average testing, the apparatus comprising:

• a processor;
• and
• a memory in communication with the processor for storing test data and instructions, wherein the processor executes instructions to perform a method of multivariate parts average testing, the method comprising:
• determining testing limits based on historic testing result data;
• testing a plurality of portions of a material according to the testing limits to obtain test results;
• computing multivariate statistics using the test results;
• computing mean or median values of the multivariate statistics;
• computing differences between the multivariate statistics and the mean or median values;
• updating the testing limits based on the mean or median values to produce updated testing limits;
• identifying a trend indicating an out of control material drift of the material based on the mean or median values and the updated testing limits;
• and
• halting testing of the plurality of portions of the material responsive to the identifying the trend.

One or more non-transitory computer-readable medium comprising program instructions stored thereon that are executable by one or more processors to implement a method comprising:

• determining testing limits based on historic testing result data;
• testing a plurality of portions of a material according to the testing limits to obtain test results;
• computing multivariate statistics using the test results;
• computing mean or median values of the multivariate statistics;
• computing differences between the multivariate statistics and the mean or median values;
• updating the testing limits based on the mean or median values to produce updated testing limits;
• identifying a trend indicating an out of control material drift of the material based on the mean or median values and the updated testing limits;
• and
• halting testing of the plurality of portions of the material responsive to the identifying the trend.
