The Economic Partnership Agreements (EPAs) between the group of African, Caribbean and Pacific (ACP) countries and the European Union could serve as an opportunity to accelerate global and regional trade integration of ACP countries. Moreover, the European Commission intends to use EPAs as a tool for development and the eradication of poverty in ACP countries. To achieve their potential develop...

The airline industry in the United States has been one of the hardest-hit (economic victims of the terrorist attacks on September 11, 2001. In an effort to reduce operating cost to better adapt to the decreasing demand, American Airlines (AA) has introduced de-peaking strategies at two of its major hubs: Chicago O’Hare and Dallas/Fort Worth International Airports. In this paper, American Airlin...

Air Traffic Flow Management (ATFM) is a challenging operations research problem whose importance keeps escalating with the unabated growth of the airline industry. In the presence of inclement weather, the problem becomes particularly serious and leads to huge monetary losses and delays1, Yet, despite massive efforts on the part of the U.S. Federal Aviation Administration (FAA), airline compani...

Airline operations depend on the complex control of many expensive, tightly-constrained, interdependent resources such as crews and aircraft. Operations research (OR) has played an important role in developing planning tools for this complex system. In recent years, however, the already intense pressure on the airline industry has dramatically increased due to rising fuel costs, competitive pri...

The New York metroplex airports (JFK, LGA, EWR) provide air transportation service to this critical international economic hub. In the summer of 2007 the flights servicing the NYC metroplex airports experienced excessive delays and cancellations that added significant costs to doing business in New York. These delays can be attributed to changes in daily airport capacity (due to weather) and to...

This paper introduces an eecient adaptation of the branch-and-bound technique that solves real-world rostering problems for airline crews. The eeciency of the algorithm is based on the exploitation of rostering-speciic properties (e.g. variable selection, branching strategy and cutting-planes), an approach that shortens the solution process and outperforms standard techniques. Furthermore, we f...

In airline schedule planning models, the demand and price information are usually taken as inputs to the model. Therefore schedule and capacity decisions are taken separately from pricing decisions. In this paper we present an integrated scheduling, fleeting and pricing model for a single airline where these decisions are taken simultaneously. This integration enables to explicitly model supply...

Airline crew scheduling is a comparably well-studied field in Operations Research. An increasing demand for higher crew satisfaction arises; especially after most relevant cost factors have been optimized to their greatest extent, mostly with secondary or little regard on quality-of-life criteria for the involved crew members. One such criterion is team-orientation. Independent from the chosen ...

For reasons of tractability, the airline scheduling problem has traditionally been sequentially decomposed into various stages (e.g. schedule generation, fleet assignment, aircraft routing, and crew pairing), with the decisions from one stage imposed upon the decision-making process in subsequent stages. Whilst this approach greatly simplifies the solution process, it unfortunately fails to cap...

Ref2: The following is a review of the manuscript, “The effects of convection on new particle formation in the free troposphere: Case studies” by Benson et al. This review pertains to a revised version of the manuscript. The case studies in this revision are improved and provide a clearer representation of the relationship between air history and new particle formation. However, the discussion ...
