US Customs embarked on a major modernization initiative of its Information Technology systems. Drawing in data from Customs trade systems, targeting inspectors review manifest information as well as strategic and tactical intelligence to determine which shipments and containers are “high-risk.” This entails a considerable level of communication and data sharing between various government agenci...

Transport networks with hub structure organise the exchange of shipments between many sources and sinks. All sources and sinks are connected to a small number of hubs which serve as transhipment points, so that only few, strongly consolidated transport relations exist. While hubs and detours lead to additional costs, the savings from bundling shipments, i.e. economies of scale, usually outweigh...

The brown treesnake (BTS) has been on Guam for about 50 years and in this period has caused extensive ecological, economic, and social damage. It has also repeatedly dispersed from Guam via the transportation network, arriving at numerous locations. However, the conditions snakes face in surface shipping are unknown, making assessment of the risk of snake survival impossible. To address this, w...

This paper investigates optimal replenishment lot size and optimal number of shipments for economic production quantity (EPQ) model with rework process using an algebraic approach. The classic EPQ model assumes a perfect quality production for all items produced and a continuous issuing policy for satisfying customer‟s demand. However, in a real life vendor-buyer integrated-production-inventory...

The fact that large manufacturing plants export relatively more than small plants has been at the foundation of much work in the international trade literature. We examine this fact using Census micro data on plant shipments from the Commodity Flow Survey. We show the fact is not entirely an international trade phenomenon; part of it can be accounted for by the effect of distance, distinct from...

Freimut Bodendorf ([email protected]) is Professor for Information Systems at the University of Erlangen-Nuremberg, Germany. Their research focuses on electronic markets. In the project FAN/EFFEKT (see references) research is conducted about efficient coordination in the service sector. Abstract Considering the way information is exchanged in the settlement phase for Trackin...

Coal is a principal fossil fuel driving economic and social development, and increases in global coal shipments have paralleled expansion of the industry. To identify the potential harm associated with chronic marine coal contamination, three taxa abundant in tropical marine ecosystems (the coral Acropora tenuis, the reef fish Acanthochromis polyacanthus and the seagrass Halodule uninervis) wer...

In recent years interorganizational communication and coordination have relied increasingly on the exchange of EDIFACT-messages. This is especially true for the logistics sector. In order for the sender to keep control over the forwarder's proper delivery process, status messages prove that certain milestones have been achieved. Taking into account that only a very small number of shipments fac...

This paper deals with the analysis of a multi-item, continuous review model of two-location inventory systems for repairable spare parts in which lateral and emergency shipments occur in response to stockouts. A continuous review basestock policy is assumed for the inventory control of the spare parts. The objective is to minimize the total costs for inventory holding, lateral transshipments an...
