The concept of flow has become particularly important in logistics and freight distribution. From a simple question of capacity, the issues of timing, frequency and punctuality are now of significant relevance in freight movements since they are part of supply chain management strategies. In particular, transport terminals and freight distribution centers have been the major elements permitting...

As state transportation planners seek to build or support sustainable transportation systems in an era of economic challenges, they find few publicly available rail analysis models for stakeholders to examine the environmental impacts, socio-economic effects and costs associated in investing in rail infrastructure. This paper, taken from a University Transportation Center Program (UTCP Region 6...

The full-truck-load route planning and scheduling with time appointment system falls in the class of Traveling Salesman Problem with Time Windows (TSPTW). In this paper, methods for improving the scheduling of intermodal trucks in deterministic and stochastic environments, where ISO containers need to be transferred between marine terminals, intermodal facilities, and end customers are investig...

This research is motivated by the extraordinary increase in the use of intermodal shipments in recent years for both domestic and global movement of freight. Three mathematical models, which explore the dynamics of intermodal hub-and-spoke networks, are presented. These models use transportation costs, fixed location costs, modal connectivity costs, modal transit times and service time requirem...

Today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchers due to the risk of this transit, which should be considered for development of industries and transportation. Therefore, a model that is useful should consider the risk and damage to humanitarian and environmental issues due to transit of hazmat materials. By considering the related cost, the r...

Queuing models are introduced for estimating container dwell times at rail intermodal terminals and transit times through rail line-haul corridors. These models are statistically calibrated on industry data. The intent of these models is to estimate changes in container flow times stemming from changes in infrastructure, staffing levels at terminals, or import volumes passing through given infr...

Intermodal transport, the combination and integration of several transport modes, with the use of loading units, is in most cases more environmentally friendly than unimodal road transport for the carriage of goods. The LAMBIT-model (Location Analysis Model for Belgian Intermodal Terminals) has been developed to analyse the market areas of existing and potential intermodal terminals. In the LAM...

In the management of container sea-rail intermodal transportation, dynamic pricing problem with uncertain conditions has significant impacts on the benefit and competitiveness of a multimodal transport operator. Based on the revenue management theory and the features of container sea-rail intermodal transport, this paper develops a two stages optimal model which integrates dynamic pricing and s...

The focus of our research is on rail transportation of intermodal containers. We address the problem of determining day-of-week schedules for both direct and indirect (via a hub) trains and allocating containers to these trains for the rail (linehaul) portion of the intermodal trip. The goal is to minimize operating costs, including a fixed charge for each train, variable transportation and han...
