The influence of the non-stationary state on the bulk-cargo terminal operation

Abstract

In this paper was discussed a process of unloading of bulk cargo by queuing theory with bulk arrival of units to the system (composition of barge). limited waiting queue and cancelation (cancelation is related to the whole composition of barge). The period of work of the system until stationary state is reached (non-stationary work order), and stationary order of work of the system were analysed as well. Non-stationary state criterion is given.

U radu je analiziran proces istovara rasutih tereta modelom teorije redova čekanja sa grupnim dolaskom jedinica u sistem (sastava barži), ograničenim redom čekanja i otkazom (otkaz se odnosi na celokupan sastav barži). Analiziran je period rada sistema do postizanja stacionarnog režima (nestacionarni režim) kao i stacionarni režim rada sistema. Dat je kriterijum nestacionarnosti.
