Method and program product to optimize manufacturing test time of electrical devices

Method comprising:

• (a) generating a test management matrix containing a plurality of locations with each location identifying at least one test to be executed in testing operability of devices in electrical machines;
• (b) selecting at least one of the locations;
• (c) providing, as inputs to said test management matrix, preferred aggregate test levels and characteristics associated with qualities of parts used to manufacture said machines, the characteristics including green, white, yellow and red;
• and
• (d) executing the at least one test on the devices to check the operability of said devices.

• selecting one of the characteristics;
• and
• selecting the at least one location at a point whereat the selected preferred aggregate test levels and selected one of the characteristics intersect;
• and
• (d) executing the at least one test on the devices to check the operability.

Method comprising:

• (a) generating a test management matrix containing a plurality of locations with each location identifying at least one test to be executed in testing operability of devices in electrical machines;
• (b) selecting at least one of the locations;
• (c) the selecting step including:
• selecting a preferred aggregate test level;
• selecting a characteristic representing quality of parts used to manufacture said devices;
• plotting on the test management matrix the selected preferred aggregate test level and the selected characteristic;
• and
• selecting said at least one location at the intersection of said selected preferred aggregate test level and said selected characteristic;
• and
• (d) executing the at least one test on the devices to check the operability of said devices.

A method for testing machines including the acts of:

• (a) providing a test management matrix with locations indicating tests to be executed;
• (b) partitioning a manufacturing period into multiple sub-periods;
• (c) for each sub-period permitting execution of a predefined test level;
• (c1) classifying parts based upon quality;
• (d) selecting one of the predefined test levels;
• and
• (e) using parts quality classification and selected predefined test level to select a location in said test management matrix.

A program product including:

• a media on which computer program is recorded, said computer program including a code set that provides a test management matrix with locations identifying tests to be executed on a product under test;
• a code set that partitioned a predefined period into multiple sub-periods;
• a code set that associates a sub-period with predefined test level;
• a code set that classifies parts based upon quality;
• a code set to select one of the predefined test levels;
• and
• a code set that uses a selected predefined test level and parts quality classification to select a location in the test management matrix.
