Abstract

A system of case-based reasoning for sensor prediction in a technical process, especially in a cement kiln, method and apparatus therefore, and wherein the system provides accurate predictions of the cement kiln behavior for a limited period into the future. The invention utilizes a method of case-base-reasoning (CBR) for the task of sensor value prediction. An apparatus for implementing the method is characterized by a database (100) in which the relevant time interval data are stored, a test generator (101) and an optimisation unit (102-104) for the selection and optimisation of the time interval data.
