The Liner Shipping Fleet Repositioning Problem (LSFRP) poses a large financial burden on liner shipping firms. During repositioning, vessels are moved between services in a liner shipping network. The LSFRP is characterized by chains of interacting activities, many of which have costs that are a function of their duration; for example, sailing slowly between two ports is cheaper than sailing qu...

The shipping sector is a significant contributor to emissions of air pollutants in marine and coastal regions. In order to achieve sustainable shipping, primarily through new regulations and techniques, greater knowledge of dispersion and deposition of air pollutants is required. Regional model calculations of the dispersion and concentration of sulfur, nitrogen, and particulate matter, as well...

As a technology based on database, statistics and AI, data mining provides biological research a useful information analyzing tool. The key factors which influence the performance of biological data mining approaches are the large-scale of biological data and the high similarities among patterns mined. In this paper, we present an efficient algorithm named IRTM for mining frequent subtrees embe...

We introduce an approach to learn discriminative visual representations while exploiting external semantic knowledge about object category relationships. Given a hierarchical taxonomy that captures semantic similarity between the objects, we learn a corresponding tree of metrics (ToM). In this tree, we have one metric for each non-leaf node of the object hierarchy, and each metric is responsibl...

Late Acceptance Hill Climbing (LAHC) has been shown to be an effective local search method for several types of optimization problems, such as on certain types of scheduling problems as well as the traveling salesman problem. We apply LAHC to a central problem in the liner shipping industry, the Liner Shipping Fleet Repositioning Problem (LSFRP). The LSFRP involves the movement of vessels betwe...

Traditional automotive supply chains are contrasted to the way automotive supply chains may be organised in the future in order to discuss the changing role of shipping companies. A shipping company’s core capabilities, business relations and service portfolio define its role. In the next few years, the traditional shipping companies may have to evolve from highly specialized, asset-based opera...

This paper quantifies how international trade affects CO2 emissions and analyzes the welfare consequences of regulating the CO2 emissions from shipping. To this end the paper describes a model of trade and the environment, compiles new data on the CO2 emissions from shipping, and estimates key parameters using panel data regressions. Results show that the benefits of international trade exceed ...
