This paper proposes a model to address the design problem of a regional logistics network. In the proposed model, the decision variables include the location and size of logistics parks. The interaction between the logistics authority and logistics users as well as the effects of economies of scale and CO2 emission taxes on the logistics network design are explicitly considered. The proposed mo…
This paper investigated if differences of the profits of the Korean and other global shipping companies were affected by the shipping route specialization. A panel data model was applied to nine shipping companies during the 2009-2015 period, to determine to what extent freight rate, bunker fuel prices, scale economies and chartered vessel ratios affected the profits. The results showed freight…
Korean shipping companies have seriously contemplated on pursuing economies of scale in order to tap the potential that Korea can generate for the seaborne cargo volume and fleet capacity, despite of latent pros and cons associated with the economies of scale. This paper shows the concentration ratio of the top four liner shipping companies in Korea is well below that of the global counterpart.…
Conventionally, shipping companies have invested in large ships to achieve economies of scale. More recently, high speed ships have been proposed as a means of achieving timely service for customers and improving shipping performance. Yet another solution offered here is to boost the cargo handling speed at port allowing for a higher number of annual round trips. Both the cost efficiency and ti…
