Abstract
Methods and apparatus to define stages for multi-variate batch control analytics are disclosed. An example method includes determining, with the processor, a current stage in a current batch process based on a current value of a batch stage parameter. The current value of the batch stage parameter determined based on process control data associated with process parameters in the current batch process. The current stage determined independent of batch events defined by at least one of a start or an end of procedures, unit procedures, operations, or phases in a batch recipe. The example method further includes applying, with the processor, a model to the current batch process, the model corresponding to the current stage.
