We consider a container routing problem with stochastic time variables in a sea-rail intermodal transportation system. The problem is formulated as a binary integer chance-constrained programming model including stochastic travel times and stochastic transfer time, with the objective of minimising the expected total cost. Two chance constraints are proposed to ensure that the container service ...

A significant and growing volume of global trade travels on container ships, and each year larger ships are introduced. For this reason, the Container Stowage Problem, a fundamental problem in marine cargo transportation involving the optimal assignment of shipping containers of various types to specific storage locations in container ship at each port in order to maximize loading and unloading...

In this paper, a spatial information-theoretic model is proposed to locate sensors for detecting source-to-target patterns of special nuclear material (SNM) smuggling. In order to ship the nuclear materials from a source location with SNM production to a target city, the smugglers must employ global and domestic logistics systems. This paper focuses on locating a limited set of fixed and mobile...

Shipmasters may have to perform unberthing without tugboat assistance when a tsunami warning is issued. Keeping this in mind, we studied emergency unberthing without tug assistance by conducting numerical simulations and full‐mission ship maneuvering simulator (SMS) experiments. A panamax class medium‐sized bulker and a pure car carrier (PCC) were used as test ships. In the...

The Inland Container Transportation Problem describes the movement of full and empty containers among a number of terminals, depots and customers in a hinterland region. A trucking company with a homogeneous fleet of trucks has to serve customers which either receive goods by inbound containers or ship goods by outbound containers. While keeping given hard time constraints the total operating t...

A set of agricultural suppliers with low demands can save on long-haul transportation costs by consolidating their product. We consider a system with stochastic demand and a single consolidation point near the suppliers. We propose a look-ahead heuristic that takes advantage of economies of scale by aiming to ship larger quantities. We experimentally compare the heuristic's performance against ...

As a comparatively cost effective, clean, and safe method of transportation, international shipping offers an important means of moving goods internationally and enables other activities such as leisure cruising.1 Many factors contribute to the development of international shipping. As an example, the evolution of ship propulsion has progressed from sailing ships to steam ships powered by coal ...

This article describes the evolution of the coastal economy in Alabama and examines the driving forces of the sustainable economy in a historical context. The input-output model was applied to assess the direct and secondary effects of output and employment in the coastal region. Results suggest that state industries are heavily dependent on waterfront-related activities in this area, which hav...

The speed optimization problem over a path aims to find a set of speeds over each arc of the given path to minimize the total cost, while respecting the time-window constraint at each node and speed limits over each arc. In maritime transportation, the cost represents fuel cost or emissions, so study of this problem has significant economic and environmental impacts. To accommodate different fu...

The adaptor protein, downstream of tyrosine kinases-1 (Dok-1), and the phosphatase SHIP are both tyrosine phosphorylated in response to T cell stimulation. However, a function for these molecules in T cell development has not been defined. To clarify the role of Dok-1 and SHIP in T cell development in vivo, we compared the T cell phenotype of wild-type, Dok-1 knockout (KO), SHIP KO, and Dok-1/S...
