Abstract

Problem solving in continuous industrial processes is often a time-consuming task where the readings from many online measurements have to be studied simultaneously. To aid the process operators of a lime kiln in this task, an application utilizing case-based reasoning (CBR) was developed. One of the factors affecting system design was the number of training cases available, which was quite small for a CBR application. The diagnostic accuracy of the system was significantly improved with weight factor optimization, where the cost function was defined to find a suitable balance between false positives and false negatives. The results indicate that there are economically profitable possibilities in using the CBR approach and tools in everyday pulp & paper production processes.
