The influence of the ship storage occupancy capacity of a feeder ship on the optimal capacity and on the considered economic indicators

Predmet ovoga znanstvenog rada je analiza utjecaja promjene popunjenosti skladišnog kapaciteta broda na optimalni kapacitet i razmatrane ekonomske pokazatelje feeder broda. Rezultati istraživanja pružaju brodarskom poduzeću mogućnost da u skladu s novonastalim ili pretpostavljenim poslovnim prilikama na određenoj liniji poduzme odgovarajuće poslovne poteze s ciljem povećanja efikasnosti pomorskoprijevozne usluge. Korištenjem modela za određivanje optimalnog kapaciteta feeder broda u radu je izvedena analiza utjecaja promjene količine tereta na relaciji između luke Rijeke kao regionalne hub luke i mogućih perifernih luka, Zadra, Splita i Ploča na optimalni kapacitet feeder broda koji bi opsluživao pretpostavljeni feeder servis. Ujedno je primjenom navedenog modela određen trend kretanja vrijednosti ekonomskih pokazatelja (rentabilnosti i ekonomičnosti) za prethodno definirani optimalni kapacitet na razmatranom plovidbenom pravcu. Također, primjenom modela u radu je izvedena i prikazana analiza promjene kapaciteta uslijed smanjenja omjera količine jediničnog tereta i skladišnog kapaciteta broda.The subject of this scientific work is to analyze the influence of the ship storage occupancy capacity variation on the optimal capacity as well as the considered economic indicators of a feeder ship. The results of the research have provided to a shipping company the possibility to take appropriate business moves in accordance with new or predicted business opportunities on a specific line aiming at improving the sea transport service efficiency. By using a model to determine the optimal capacity of a feeder ship, the paper aims at analyzing the influence of the change in the amount of cargo between the port of Rijeka, as a regional hub port, and the possible peripheral ports of Zadar, Split and Ploče on the optimal capacity of a feeder ship operating in the presumed feeder service At the same time, by using ditto model, a specific trend in the movement of economic indicator values (cost-effectiveness and economic justifiability) is determined for the previously defined optimal capacity on the considered route. Moreover, an analysis of the capacity changes due to the reduction in the cargo quantity and ship storage capacity ratio is carried out and presented in this paper by using the same model
