碩士 / 國立交通大學 / 運輸科技與管理學系 / 90 / In recent years, transoceanic containerships are built larger and larger so as to lead to the formation of marine hub-and-spoke network. In the networks, large ships run between hub ports, while small ships are used as feeders between feeder ports.
In the networks, the factor for the liner to operate depends on the ability to produce the profit. A containership berths more ports will not only increase the operation costs, but also generate the revenue. The critical point is the effect of trade off (revenue - cost) will benefit for the containership routing. However, the previous models were unable to provide the liner with the selection of the hubs in order to seed maximum profit. The main purpose of this paper is, therefore, to propose a hub-and-spoke model of routing containerships to solve the problem.
The model consists of two parts. One, Model 1 decides the location of hub ports. The other, Model 2 assigns adequate feeders on the branch network. The total sum of two objective values in models is the maximum profit. The concept of HEUR 1 which O’Kelly proposed in 1987 is used to solve the function of Model 1. Model 2 decides the number of feeders on branch network, given the loop type routing to match with the traffic flow. This paper ends with an application of the real Trans-Pacific routing and the sensitivity analysis.
