Abstract

In Poland problem related to lack of rolling stock occurred recently. This article presents a comparison between two forecasting methods of realized transport work and transported freight mass by railway. The obtained results are also compared on a monthly and quarterly data basis. Knowing the exact values of forecasts railway carriers can plan the number of rolling stock. The calculations show that using the data as a monthly basis, the most reliable results can be obtained using the Holt model, while calculating data for quarterly basis results is closer to the real values using the Winters model.

Abstract

This article considers factors of number of sidings and the occurrences of transit traffic and presents a comparison of selected railway lines in Poland. Multi-criteria analysis methods were used, like the zero unitarization method and the technique for order preference by similarity to ideal solution method. The comparison made it possible to arrange the selected railway lines in the order from the most to the least useful. The obtained results showed also that zero unitarization method is limited only to the analysis of all lines on which transit traffic occurs or all lines without transit traffic. The comparison of all lines is possible using the technique for order preference by similarity to ideal solution method.
