Continuous growth in air cargo deliveries and increasing competition is necessitating freight forwarders to develop innovative solutions to improve performance and reduce costs. This study considers a freight forwarder's operational implementation of alternative access airport policy in a multi-airport region for air cargo transportation. Given a set of heterogeneous air cargo customers, the fo...

The SECAIR project provides an event-driven architecture for dealing with spatio-temporal requirements. It adopts a multi-sensor data fusion process to handle with event streams emitting continuously location based data regarding a vast number of different business objects. It is therefore well-suited for business activity monitoring, supporting managers at analysing and processing complex even...

Both the single-airport ground-holding problem (GH) and the multi-airport ground-holding problem can be extended by the addition of banking constraints to accommodate the hubbing operations of major airlines. These constraints enforce the desire of airlines to land certain groups of flights, called banks, within fixed time windows, thus preventing the propagation of delays throughout their enti...

Deep convolutional neural network (CNN) achieves outstanding performance in the field of target detection. As one of the most typical targets in remote sensing images (RSIs), airport has attracted increasing attention in recent years. However, the essential challenge for using deep CNN to detect airport is the great imbalance between the number of airports and background examples in large-scale...

Multi-modal logistics chains are those transportation processes in which different modes of transportation are involved for the delivery of goods. These modes are adopted in consecutive legs, which have to be synchronized. An example scenario is the delivery of goods from a production center in New York, USA, to a plant in Utrecht, the Netherlands. The transportation chain consists of two legs:...

African regional organizations’ increasing activity in security policy is usually approached through the concept of a ‘security community’, which can only partially clarify their difficult situation. A multilevel governance model is suggested as a more useful approach in a situation where economic cooperation is weak, member states’ principles of governance diverge, and they themselves might be...

Net product entry is procyclical, which amplifies fluctuations in consumer welfare over the cycle if consumers have love for variety. Using barcode-level data covering grocery expenditures in 26 major cities, I establish that differences in city-level product entry are largely uncorrelated with local economic conditions. I provide evidence that city-level changes in product variety over the bus...

Researches in crowd simulation tend to study systems which are more and more complex, large and realistic. Several models are using multi-agent based simulation in which agents are modeling pedestrians. In this case the system’s environment is a key concept which represents and manages the virtual world in which the agents are living. This paper proposes the definition of a multi-level environm...

European transport policy promotes intermodality as a means of improving efficiency and sustainability. This study looks into passenger air-rail intermodality at airports which are directly integrated into long-distance rail networks and focuses on intermodal journeys in which the rail trip doesn’t serve the purpose of city-centre to nearby airport access, but rather makes up a substantial leg ...
