Abstract
Industrial systems produce a lot of information for operators. Increased mesurement information flow might cause difficulties for the operators to observe the process states and faulty process operation. In this study, measurements and statistical variables are combined by fuzzy logic to generate key factors in several points in the continuous cooking digester. The overall diagnosis system combines the key factors into one system which is used in the operational purposes and as a helping tool for process condition monitoring.
