Resumen
This article presents the issue of availability of transport services on the Odra Waterway. The study involved the analysis of the number of days of maintaining the transit depth between years 1982 and 2005 on the three sections of the Odra. On this basis the actual navigable day intervals for two representative barges BM-500 and BP-500 were determined. The analysis shows the relationship between the mass of transported cargo and the number of navigable days. The results are the basis for further work on developing decision-making models supporting the implementation of innovative transport processes.
