Despite air transport being the safest way to travel, accidents still happen, which incur massive costs and many consequences for industry society. The main objective of this research is determine financial impact crashes by distinguishing between fatal non-fatal events their effect on market stock price involved companies airlines manufacturers. This study also aims contribute literature about...

This paper is the second of two papers entitled “Airline Planning Benchmark Problems”, aimed at developing benchmark data that can be used to stimulate innovation in airline planning, in particular, in flight schedule design and fleet assignment. The former has, to date, been under-represented in the optimization literature, due in part to the difficulty of obtaining data that adequately reflec...

Through implementation of its 2000 pharmaceutical reform, the South Korean government expected to reduce the cost of medications and improve service levels, medical appropriateness of care, and drug effectiveness. However, despite the reform's lofty goals, unintended consequences have distorted the supply of medical services and spending. These consequences have included increasing the use of u...

The ongoing debate about vaccine passport policies for dealing with COVID-19 has necessitated analyzing its effectiveness in the airline and tourism industry. This study was purposed to analyze how passports are evaluated by multiple stakeholders, such as investors passengers leisure/vacation purposes. findings of first show that implementation is positively investors. results second highlight ...

In this paper, a stochastic programming approach is applied to the airline network revenue management problem. The airline network with the arc capacitated single hub location problem based on complete–star p-hub network is considered. We try to maximize the profit of the transportation company by choosing the best hub locations and network topology, applying revenue management techniques to al...

The maintenance of aircraft components is crucial for avoiding aircraft accidents and aviation fatalities. To provide reliable and effective maintenance support, it is important for the airline companies to utilise previous repair experience with the aid of advanced decision support technology. Case-based reasoning (CBR) is a machine learning method that adapts previous similar cases to solve c...

Purpose: The network strategies used by airline carriers have been a recurring subject in air transport research. The aim of this paper is to investigate the relationship between the different operational characteristics of the airline and its route network configuration. Design/methodology/approach: The two main airline carrier typologies Full-Service and Low-Cost carriers – are analysed using...

We proposed a new Small-World network (called n-Star network in which average path-length L becomes absolutely small) inspired by ants’ collective behavior. As one of the real-world applications using this network, it is shown that reorganization of the world airline network is possible in the next generation. In addition, it not only has the characteristic that is more immune from random failu...

Background The 2015 Germanwings Flight 9525 disaster, in which 150 people were killed after the co-pilot may have intentionally crashed the plane in a suicide attempt, highlights the importance of better understanding the mental health of commercial airline pilots. However, there have been few systematic reviews investigating the topic of mental health in commercial aviation. This systematic re...
