The raison d’etre for the air transportation system is the movement of passengers and cargo. Consumer information for airline passengers and regulatory consumer protection of airline services provide measures of performance using the percentage of on-time flights, and the percentage of cancelled flights. Researchers have shown that these “flight-based” metrics are a poor proxy for measuring the...

Delay management for public transport consists of deciding whether vehicles should wait for delayed transferring passengers, with the objective of minimizing the overall passenger discomfort. We model the underlying transportation network as a directed acyclic graph, where edges represent trains, and weighted paths represent passenger flows. Given initial delays of some of the passenger paths, ...

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...

OBJECTIVE The history and etiology of airline passenger misconduct are discussed and relevant medico-legal and management implications reviewed. METHOD The medical literature was reviewed and supplemented with internet searches for relevant information. Organizations including the Federal Aviation Administration, International Air Transport Association, Transportation Safety Board of Canada, ...

Disruptions in airline operations can result in infeasibilities in aircraft and passenger schedules. Airlines typically recover aircraft schedules and disruptions in passenger itineraries sequentially. However, passengers are severely affected by disruptions and recovery decisions. In this paper, we present a mathematical formulation for the integrated aircraft and passenger recovery problem th...

This paper reviews three different approaches to determine the torsion stiffness of an automotive chassis and presents a Finite Element Analysis based method to estimate a vehicle’s torsion stiffness. As a case study, a typical sedan model is analyzed and the implementation of the presented methodology is demonstrated. Also presented is a justification of assuming linear torsion stiffness when ...

PURPOSE To develop and compare effective strategies for depleting graft-derived passenger leukocytes that include antigen-presenting cells from corneal buttons and to assess the effectiveness of this strategy in promoting graft survival using a high-risk (HR) model of corneal transplantation. METHODS Corneal buttons harvested from C57BL/6 mice were used in three ex vivo strategies of passenge...

This paper aims to develop a multi-objective model for scheduling cargo trains faced by the costs of tardiness and earliness, time limitations, queue priority and limited station lines. Based upon the Islamic Republic of Iran Railway Corporation (IRIRC) regulations, passenger trains enjoy priority over other trains for departure. Therefore, the timetable of cargo trains must be determined based...
