In airline industries, the aircraft maintenance cost takes up about 13% of the total operating cost. It can be reduced by a good planning. Spare parts inventories exist to serve the maintenance planning. Compared with commonly used reorder point system (ROP) and forecasting methods which only consider historical data, this paper presents two non-linear programming models which predict impending...

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...

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...

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...

Airline cargo transportation is the preferred system as fastest way today. However high costs also lead to prices. Therefore, pricing one of issues that businesses should pay most attention when planning. Although competition over price a competitive factor do not want enter, this situation has become inevitable due intensity competition. To cope with situation, it beneficial for constantly mea...

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...
