Abstract:
1. A computing system for monitoring activity in an automated fabrication facility occurring as part of a manufacturing process in which work-in-process material lots undergo events including multiple manufacturing operations and intermediate storage operations, the computing system comprising: a computer operably coupled to a manufacturing execution system database having data relating to events including: loading and unloading of the work-in-process material lots from manufacturing equipment; loading and unloading of work-in-process material lots from storage equipment; transfer of the work-in-process material lots via an automated material handling system; beginning and completion of individual manufacturing operations; requests for the transfer of the work-in-process material lots by the automated material handling system; and the computer also being operably coupled to an automated material handling system database having data relating to movement of the work-in-process material lots between the manufacturing operations and the storage operations; and a solver product operatively installed on the computer for processing information regarding timing of the events and information regarding operation of the automated material handling system to generate a report regarding performance of the automated fabrication facility, wherein the report identifies information regarding a sequence of events having occurred in the manufacturing process.
