Container Arrivals Forecasting Practice And Experience At Marine Terminals, Alexios C. Sideris
Container Arrivals Forecasting Practice And Experience At Marine Terminals, Alexios C. Sideris
Theses
The advent of the container traffic in maritime transportation has led during its 40-year long history to novel perceptions and operation planning requirements for the port container terminal. A major requirement in this respect refers to the efficiency of the operations in the container transfer between the different modes. The current study presents a methodology on the development of a forecasting tool to access the service demand patterns at a marine terminal on per day basis. A set of forecasting models was introduced and their implementation difficulties were explored. The main effort in this approach was to replicate the distribution …
Optimizing Rail-Truck Intermodal Drayage Operations, Wen Zhang
Optimizing Rail-Truck Intermodal Drayage Operations, Wen Zhang
Theses
This thesis presents a case study of the trucking (or drayage) portion of rail-truck intermodal freight transportation. The approach used was to examine in detail the current costs and potential for improvement at one New Jersey intermodal terminal. The analysis is conducted using a mathematical programming model to find an optimal scheduling plan for the drayage operation. To solve the model more efficiently, a modification is made to explore the special structure of the original problem which has a sparse constraint matrix. The model is solved first with an objective function that minimizes the total cost of the operation, and …
Reducing Rail-Truck Freight Intermodal Drayage Costs, David Moy Jr.
Reducing Rail-Truck Freight Intermodal Drayage Costs, David Moy Jr.
Theses
In rail-truck intermodal transport, a highway truck-trailer or container is moved by truck from a shipper to a rail terminal in the shipper's vicinity, and by rail in line haul between rail terminals. Upon being unloaded at the destination rail terminal, the container is delivered to a receiver (consignee) by truck. The highway portion of the move, or drayage, accounts for a relatively high percentage of total origin to destination cost, and it limits severely the competitiveness of intermodal service with door-to-door truck service. The approach used in this thesis is to examine in detail the current costs and potential …
