This paper discusses a decision support system for airline and railway crew planning. The system is a state-of-the-art branch-and-price solver that is used for crew scheduling and crew rostering. We briefly discuss the mathematical background of the solver, of which most part is covered in the Operations Research literature. Crew scheduling is crew planning for one or a few days that results in...

Next to fuel costs, crew costs are the largest direct operating cost of airlines. Therefore much research has been devoted to the planning and scheduling of crews over the last thirty years. The planning and scheduling of crews is usually considered as two problems: the crew pairing problem and the crew assignment (rostering) problem. These problems are solved sequentially. In this paper we foc...

Modern aircraft have thousands of parts, systems, and components that need to be recurrently inspected or replaced. To keep the fleet airworthy, maintenance planners schedule checks for each associated tasks. In practice, these two complex problems are solved following experience planners, resulting in sub-efficient solutions. This paper presents first decision support system (DSS) developed op...

Airports are important infra-structures for the air transportation business. One of the major operational constraints is the peaks of passengers in specific periods of time. Airline companies take into consideration the airport capacity when building the airline schedule and, because of that, the execution of the airline operational plan can contribute to improve or avoid airport peaks problems...

The airline industry has shown significant growth in the last decade according to some indicators such as annual average global air traffic passenger demand and rate transport fleet. This inevitable progress makes challenging forces companies produce a range of solutions that increase consumer loyalty brand. These reduce high costs encountered operations, prevent delays planned departure times,...

This paper presents several very interesting diagnostics for a comprehensive process-oriented validation of CCMs and CTMs in the upper troposphere/lower stratosphere (UTLS) and their application to the GMI CTM. It hence is a valuable contribution to ongoing validation activities within the different communities (e.g. QUANTIFY or CCMVal). However, the presentation and discussion of some diagnost...

Broadly defined, revenue management (RM) is the process of maximizing revenue from a fixed amount of perishable inventory using “market segmentation” and “demand management” techniques. While RM is not new (in fact it is as old as commerce, e.g., haggling in a market can be considered a form of RM), the theory and practice of RM have seen significant scientific and practical advances in the las...

The competitors in the airline industry often rely on pricing strategy to capture more sales as a main mean of competition. Thus, dynamic pricing is often utilized to maximize profit while allowing better pricing against competition at the same time. In order for dynamic pricing to be effective, airline company has to take in consideration both internal and external information. Tactical pricin...

Changes in the U.S. domestic airline route system have increased competition between international gateways. To assist in understanding this phenomenon, a system of models that predicts airline passenger flows resulting from different airline gateway hubbing strategies has been developed. The calibrated rnodels predict baseline passenger Mows quite accurately. The system was then used to projec...
