ABSTRACT:
A system for performing statistical process control. A storage device stores a plurality of SPC charts, specifying data collected from a system during testing. A controller categorizes the SPC charts into a plurality of groups based on characteristics thereof. A detector determines whether the charts in any of the groups violate a preset rule. An alarm generator generates alarm information identifying the chart violating the rule.
