Abstract:
1. A method for identifying an incompatible combination of manufacturing tools in a manufacturing facility, the method comprising: receiving measurements of products that were subject to a manufacturing process involving a plurality of manufacturing tools, said measurements pertaining to a performance characteristic of each product; evaluating whether each manufacturing tool implemented in said manufacturing process individually performs normally, on average, when implemented in a sequential combination with other tools, based on the received measurements; responsive to evaluating each manufacturing tool implemented in said manufacturing process individually performs normally, evaluating whether a first combination of the manufacturing tools operating together in a sequential process perform normally based on the received measurements, said evaluating said first combination comprising: generating a notification message, based on the evaluating that each manufacturing tool individually performs normally but the first combination of the tools perform abnormally, wherein a computing system including at least one processor and memory device performs one or more of: the receiving, the evaluating whether each manufacturing tool individually performs normally, the evaluating whether the first combination of the manufacturing tools together perform normally, and generating the notification message.
