In addition to the increasing passenger demand, airline frequency competition is another reason for the growing demand for airport resources. By providing more flight frequency, an airline attracts more passengers. As a result, demand for flight operations often exceeds capacity at congested airports, resulting in delays and disruptions. At some congested airports, the limited airport capacity ...

The cost of ight crews is the second largest operating cost of an airline. Minimizing it is a fundamental problem in airline planning and operations, and one which has leant itself to mathematical optimization. We discuss several recent advances in the methods used to solve these problems. After describing the general approach taken, we discuss a new method which can be used to obtain approxima...

Airline maintenance task scheduling takes place in a disruptive environment. The stochastic arrival of corrective tasks and changes both fleet resource availability require schedules to be continuously adjusted. An optimal schedule ensures that all are executed before their due date an efficient (at minimum use ground-time) stable (limited number changes) manner. This paper is the first study a...

Scheduling landings of aircrafts is an essential problem which is continuously solved as part of the daily operations of an airport control tower. All planes in the airspace of an airport are to be assigned to landing slots by the responsible air-tra c controller. The support of this decision problem with suited optimization approaches has a long lasting tradition in operations research. Howeve...

Currently, flight delays are common and they propagate from an originating to connecting flights, leading large disruptions in the overall schedule. These cause massive economic losses, affect airlines' reputations, waste passengers' time money, directly impact environment. This study adopts a network science approach for solving delay propagation problem by modeling analyzing schedules histori...

Since the pioneering work of O’Kelly[5], designing an airline network has been an alluring topic in operations research studies, and seemingly hub location problems are main concerns in the literature, see [1] for recent survey. In this paper a different approach is taken to the design problem in an attempt to find a compact and efficient sub-network of the original airline network. In Fig. 1 J...

The Airline Operations Control Centre (AOCC) tries to solve unexpected problems that might occur during the airline operation. Problems related to aircrafts, crewmembers and passengers are common and the actions towards the solution of these problems are usually known as operations recovery. Usually, the AOCC tries to minimize the operational costs while satisfying all the required rules. In th...

The Airline Operations Control Center (AOCC) tries to solve unexpected problems that might occur during the airline operation. Problems related to aircrafts, crewmembers and passengers are common and the actions towards the solution of these problems are usually known as operations recovery. In this paper we present the implementation of a Distributed Multi-Agent System (MAS) representing the e...

This paper introduces the notion of policy as a basis for interaction for decision-support systems, and describes how policy was applied as the foundation of a decision-support tool to aid in diversion management in airline operations. A policy is an abstract, general, a priori statement of expressing a goal and an associated priority. Diversion management is the process of deciding which incom...
