The objective of this paper is to identify some of the main issues in freight transportation
planning and operations, and to present appropriate Operations Research models and …

The aim of this paper is to present a survey of recent optimization models for the most
commonly studied rail transportation problems. For each group of problems, we propose a …

Freight transportation is a vital component of the economy. It supports production, trade, and
consumption activities by ensuring the efficient movement and timely availability of raw …

Intermodal transport between road and rail, also known as combined transport, has received
a large interest in recent years as part of a possible solution for a sustainable and efficient …

We propose a dynamic model for optimizing the flows of flatcars that considers explicitly the
broad range of complex constraints that govern the assignment of trailers and containers to …

We present the main freight transportation planning and management issues, briefly review
the associated literature, describe a number of major developments, and identify trends and …

In this article, we discuss the state of the practice in optimization systems to distribute empty
railcars to shippers by two major US freight railroads, BNSF and CSX. We describe the …

Dynamic fleet management problems (with a homogeneous fleet) are classically formulated
as dynamic networks, or linear programs with side constraints. Recently, a new dynamic …

We study the deployment planning problem (DPP) that may roughly be defined as the
problem of the planning of the physical movement of military units, stationed at …

Dynamic fleet management problems with multiple equipment types and limited substitution
can be modeled as dynamic, multicommodity network flow problems. These problems are …
