Abstract
The publication presents the prognostic methodology used in forecasting of quantity of steel production. On the basis of empirical data (yearly steel production) from period 2000 - 2017, forecasts of steel production for Poland until 2022 were estimated. The prognostic methodology in the first step consisted in: determining separate forecasts for: steel production in total and BOF steel and EAF steel. In the second step the equations were used: total steel production – (minus) BOF steel = (is) EAF steel and total steel production – (minus) EAF steel = (is) BOF steel. The forecasting methodology adopted was possible because the sum of BOF and EAF processes is the total production (100 %) in the steel sector in Poland.
