Maximum independent set in planning freight railway transportation

Evolutionary Freight Transportation Planning

In this paper, we present the freight transportation planning component of the INWEST project. This system utilizes an evolutionary algorithm with intelligent search operations in order to achieve a high utilization of resources and a minimization of the distance travelled by freight carriers in real-world scenarios. We test our planner rigorously with real-world data and obtain substantial imp...

Planning Robust Freight Transportation Operations

Freight Transportation Planning and Logistics

A well-functioning freight transportation system is an essential element in any successful economy. However, at the beginning of the new millennium, the prediction is that the demand for goods movement will outstrip the rate of improvements to the physical infrastructure. Marked growth in time-sensitive freight markets will tax demands on a system that already is operating near capacity in some...

Collaborative Planning in Intermodal Freight Transportation

Very few research efforts have been spent on the coordination of plans and operations of independent carriers in an intermodal transportation chain. The impact of this lack of collaboration and coordination is shown in an accordant scenario and first ideas are presented to overcome this situation following the principles of decentralized planning.

A mathematical model for hazmat and freight transportation in railway networks

In this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. In the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. It is assumed that the sequence of the trains in the network is known. The objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
