Claim:
1. A method comprising: calculating, using a processing device, an unbiased estimation of a plurality of independent model intercepts based on a state space model associated with a manufacturing facility; determining whether to perform a pilot run in the manufacturing facility; upon determining that the pilot run is to be performed, generating an indication that the pilot run is to be performed; receiving pilot run data in response to the pilot run being performed; estimating a delta offset, corresponding to equipment maintenance, for each of the plurality of independent model intercepts, wherein each delta offset corresponds to a difference in the delta offset's respective independent model intercept before and after equipment maintenance was performed, wherein the equipment maintenance was performed after the unbiased estimate of the plurality of independent model intercepts was calculated and before the pilot run was performed; and updating a state of the state space model based on the received pilot run data and on the estimated delta offsets.
