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

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 Ploce 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.
