US Patent 9429939 Multivariate monitoring of a batch manufacturing process

A method, controller, and system for monitoring a manufacturing process are described. Measured values of multiple variables, including dependent variables, manipulated variables, or both, are received. Future values of the manipulated variables, future values of the dependent variables, or both, are predicted. A multivariate analysis is performed on a combination of (1) the measured values of the variables and (2) the future values of the manipulated variables, the future values of the dependent variables, or both, to generate multivariate statistics.
