SYSTEM AND METHOD FOR VISUALLY REPRESENTING TIME-BASED DATA
A method performed by one or more computers for processing and displaying time-based data. The method includes storing manufacturing information including information about items, tests, test stations, and results of tests, in a database; sorting the stored manufacturing information in chronological order; tabulating a distance matrix with the sorted information, the distance matrix indexed by one or more of said items, said different tests, and said test stations; and displaying on a display monitor the distance matrix as a graph comprising of a plurality of test steps depicted as a series of diagram nodes and including tests or test stations, test transitions between each test step depicted as a series of arrows and including values for respective test transitions, test step descriptions corresponding to each respective test step, and test results corresponding to said each respective test step.
1 . A method performed by one or more computers for processing and displaying time-based data, the method comprising:
storing manufacturing information including information about items, tests, test stations, and results of tests, in a database;
sorting the stored manufacturing information in chronological order;
tabulating a distance matrix with the sorted information, the distance matrix indexed by one or more of said items, said different tests, and said test stations; and
displaying on a display monitor the distance matrix as a graph comprising of a plurality of test steps depicted as a series of diagram nodes and including tests or test stations, test transitions between each test step depicted as a series of arrows and including values for respective test transitions, test step descriptions corresponding to each respective test step, and test results corresponding to said each respective test step.
2 . The method of claim 1 , further comprising incrementing the values in the tabulated distance matrix to indicate passing of an item through a test step.
3 . The method of claim 1 , wherein said values for respective test transitions include one or more of the group consisting of count of test steps having a certain test result, count of all test steps, count of items with said certain test result, count of all items, and percentage of items having said certain test result relative to items not having said certain test result.
4 . The method of claim 1 , wherein said values for respective test transition include one or more of the group consisting of a first-pass-yield indicating a first test result of an item at a test step, and time between tests.
5 . The method of claim 1 , wherein each of said test steps includes one or more of the group consisting of a test type, location of a test station, an test station type.
6 . The method of claim 1 , wherein said test steps depicted as a series of diagram nodes are displayed horizontally across said display monitor.
7 . The method of claim 1 , wherein said test steps represent test stations only and are depicted as a series of diagram nodes are displayed vertically across said display monitor.
8 . The method of claim 1 , wherein each of said test steps represent a test containing all information related to said test type.
9 . The method of claim 1 , wherein each of said test steps represent a single physical test station showing the items flowing in and out of the test station as the items being tested.
10 . The method of claim 1 , wherein said displayed test results include pass or fail.
11 . The method of claim 1 , further comprising depicting repair results for the items corresponding to respective test steps.
12 . The method of claim 1 , further comprising dynamically repositioning one or more of said displayed series of diagram nodes including the information associated with said one or more of said displayed series of diagram nodes.
13 . The method of claim 1 , further comprising filtering selected data to prevent display of said selected data.
