Abstract
The goal of presented work is an attempt to design an industrial control system that uses the production data registered in the past during the regular production cycle. The main idea of the system is processing of the production data in order to find some registered past cases of production that are similar to the present production period. If the found production past case fulfills the requirements of the given quality criterion, the registered control signals corresponding to that case are considered as the pattern for the actual control. Such approach is consistent with the core assumption of Case-Based Reasoning, namely that similar problems have similar solutions. The paper presents preliminary results of the implementation of the CBR system to industrial control of the oxidizing roasting process of sulphide zinc concentrates.
