Abstract
In industrial continuous cooking systems, yields are seldom measured on-line. In this study, profiles for lignin, carbohydrates and total yield are constructed using physical model. The yield profiles are utilized for two kinds of digesters: conventional and Downflow Lo-Solids cooking processes. The total yield is also predicted using fuzzy clustering model.
