Industrial heating furnaces can conduct simultaneously several different, often closely inter-related high temperature processes. When controlling such individual processes using local control loops mutual influence of these processes on each other should be taken into account. The need to take into account the interaction is particularly important in optimizing control loops as this influence is appears in displacement (drift) of static characteristics of optimized processes due to actions made in the process of disturbances from other control loops. Introduction of processes interaction makes additional requirements for the implementation of control loops for individual process parameters, including requirements for algorithms of optimizing paths
