| Summary | Nowadays containership liner service is the major way to transport containers by sea. In order to offer better service and spend less cost, shipping carriers are facing the containership routing problem. This problem has become more complicated because shipping carriers not only design one containership line, but also bundle of lines that construct a liner service network. For instance, a major shipping carrier may have seven containership lines for the trans-pacific service. Furthermore, containership lines can be operated by shipping carriers themselves as well as with help of consortium, leasing or exchanging container slots from other carriers. This paper makes an attempt to develop an optimization model to assist shipping carriers to solve this containership routing problem. The optimization model is formulated as a multicommodity network design problem, which takes ship flows and container flows into account. That is, if containership lines are designed, ships will periodically visit en route ports in their lines, and containers can be unloaded or loaded in these ports and transported from their origins to their destinations. Furthermore, designed containership lines are divided into oceangoing ones and feeder ones. This optimization model is tested by some test cases. The results seem promising. This model is expected to help shipping carriers to solve the containership routing problem. |
