The purpose of this paper is to analyze spatial competition, congestion and flows of container imports into the United States. An intermodal network flow model is developed and used to analyze congestion in the logistics system for container imports. The results indicate that congestion exists...

This paper analyzes the intermodal transportation network of containerized imports to the United States. An optimization model is developed that integrates international and North America inland transport networks. The results indicate optimal ship size, route, port, and interior shipping...

The rapid growth of container shipments has exacerbated congestion at ports and railway corridors. The purpose of this paper is to analyse congestion in the logistics channels for container imports into the United States. A spatial stochastic optimisation model was specified which optimises...

ABSTRACT Changes in grain handling technologies and favorable terms on rail services are encouraging construction of state of the art grain handling facilities. Given these are high fixed and low marginal cost operations that are becoming increasingly vertically interdependent, the investments...

Changes in crops, increased demand, reductions in natural gas prices, and spatial competition among producers and imports are affecting the nitrogen fertilizer industry. A spatial competition model of the US nitrogen fertilizer industry was developed to determine the likely future spatial...

Wheat protein is one of the most important specifications used in domestic and import purchase contracts and is used partly as a proxy for functional quality. The purpose of this article is to analyse the demand for wheat delineated by protein class. A choice-based econometric model is specified...
