Abstract:
Apparatus and methods controlling a process producing segments of product wherein a destabilizing event of a particular type periodically destabilizes the process, resulting in product or process deviation from a target parameter associated with a number of segments of the product, from segment number to segment number n. The method associates, with respective ones of the n units of product, deviation amounts corresponding to historical deviation amounts for the respective so-numbered units of product in past occurrences of the particular type destabilizing event, and applying to selected ones of the n segments of product correction factors derived from respective associated historical deviation amounts for the respective units of product, thereby making pro-active adjustments to respective ones of the n units of product, upon occurrence of the destabilizing event. Preferred methods include applying the correction factors to each of the n units of product. Preferred correction factors are registration factors.
