The importance of "broader" economic effects of transportation infrastructure has recently become apparent. "Broader" refers to impacts beyond the geographic boundaries within which the infrastructure investments are undertaken. Approaches to estimate "broader" impacts in production and cost...

This paper studies job assignments for automated guided in container terminal settings under various conditions of uncertainty. An introduction to their operation is provided, along with a flexible dispatching algorithm, suitable for real-time control of AGVs. Using these concepts a new AGV...

Using data from online customer ratings, we explore how the relationships between logistics performance and customer loyalty are affected by risk characteristics of products and efficiencies of the websites. Risk is defined in terms of price and ambiguity of products. Efficiency is interpreted...

This paper reports on an empirical study that examined a suite of distribution and logistics services commonly used to manage inbound materials en route to plants. The sourcing decision is examined through the lenses of transaction cost economics and the resource-based view of the firm and the...

Analytical modeling and insights, numerical experiments, and real-world tour data are used to understand the impact of congestion on urban tour characteristics, carriers' costs, and distance/time traveled. This paper categorizes tours into three classes based on their tour efficiency and...

A train slot selection model based on multicommodity network flow concepts is developed for determining freight train timetables for scheduling rail services along multiple interconnected routes. The model seeks to minimize operating costs incurred by carriers and delays incurred by shippers...

This paper studies the heterogeneous fixed fleet vehicle routing problem (HFFVRP), in which the fleet is composed of a fixed number of vehicles with different capacities, fixed costs, and variable costs. Given the fleet composition, the HFFVRP is to determine a vehicle scheduling strategy with...

In this paper, we present a regression-based methodology that can estimate the Less-than-Truckload (LTL) market rates with high reliability using an extensive database of historical shipments from continental United States. Our model successfully combines the quantitative data with qualitative...

A block is the basic unit of storage space in container terminals. This study proposes two methods for optimizing the block size, by considering the throughput requirements of yard cranes (YCs) and the block storage requirements. To estimate the YC performance, cycle-time models of various...
