Abstract: A method includes identifying a target substrate process operation start time. The start time corresponds to a time of initiation of one or more substrate process actions. The method further includes providing to a model first one or more parameters of a gas transfer system associated with the substrate process operation. The method further includes obtaining first output from the model. The first output includes an indication of a first preemptive time period for initiation of first one or more gas delivery actions. The method further includes updating a process recipe. The process recipe is updated in accordance with the first preemptive time period. Updating the process recipe is to cause the first one or more gas delivery actions to deliver a first process gas to a process chamber within a threshold time window of the substrate process operation start time.
