- Abstract
- The article presents the results of forecasting the volume (size) of steel production in Poland based on selected adaptation models. The data used in forecasting were the annual size of steel production in the period from 2000 to 2017. Data on the size of steel production in Poland were obtained from reports of both the Polish Steel Association in Katowice (Poland) and the World Steel Association. The accuracy of predictions was determined by the values of real deviation of forecasted variable from forecasts (extinguished - ex post) using square root calculated from mean square error of apparent forecasts, ie RMSE - Root Mean Square Error and mean value of relative error of expired forecastsY. Forecasts can be used in making decisions in metallurgical enterprises for building production scenarios. (original abstract)
