The use of generalized evaluation of costs and engineering metallurgical process quality for selection of rational control mode for a ladle furnace unit, taking into account the production quality and acceptability of equipment operating procedure, is suggested in the paper. An assumption is accepted that a large-scale plant technologist is interested in acquiring quality products in the process of non-emergency equipment operation with no traceable, controllable over-expenditure of resources. On this assumption it is advisable to use generalized cost evaluations determined on the basis of current expenditure-planning standards ratio for the process optimization. The calculated relation between generalized process quality and cost evaluations of different process durations are used in the training simulation for metallurgical personnel and in management guidelines for changing general operation duration of steel processing. It is shown that integration of generalized evaluations of quality and expenditures in the process of education of technical personnel at metallurgical works is the special feature of the developed software. It should be mentioned that the best education results can be achieved in the case of joint usage of generalized evaluations and the system of information support of process simulation, paying attention to causes and sequences of arisen tendencies.
