A method includes determining queue times associated with operations of a sequence recipe. The operations are associated with production of substrates in a substrate processing system. The method further includes generating a schedule based on the queue times. The method further includes transmitting the schedule to a controller of the substrate processing system. The controller is to control the substrate processing system to produce the substrates based on the schedule.

A method includes identifying a bottleneck operation of a plurality of operations in a sequence recipe. The plurality of operations are associated with transporting and processing a plurality of substrates in a substrate processing system. The method further includes determining, based on the bottleneck operation, a takt time for the plurality of substrates. The takt time is an amount of time between a first substrate entering the substrate processing system and a second substrate entering the substrate processing system. The method further includes determining a plurality of queue times. Each of the plurality of queue times corresponds to a respective operation of the plurality of operations. The method further includes causing, based on the takt time and the plurality of queue times, the plurality of substrates to be processed by the substrate processing system.
