A flight-leg-based crew recovery model for disruptions management: A Tabu Search approach [PDF]

International Journal of Research in Industrial Engineering
Airlines face severe challenges due to various types of flight disruptions, such as natural disasters, bad weather, technical issues, or crew absence, which the flight recovery process can alleviate their adverse effects. This paper proposes a new flight-

A cohort study of the recovery of health and wellbeing following colorectal cancer (CREW study): protocol paper [PDF]

BMC Health Services Research, 2012
Background The number of people surviving colorectal cancer has doubled in recent years. While much of the literature suggests that most people return to near pre-diagnosis status following surgery for colorectal cancer, this literature has largely ...

An Iterative Approach to Robust and Integrated Aircraft and Crew Scheduling [PDF]

, 2010
In airline scheduling a variety of planning and operational decision problems have to be solved. We consider the problems aircraft routing and crew pairing: aircraft and crew must be allocated to flights in a schedule in a minimal cost way.

Scheduling airline reserve crew using a probabilistic crew absence and recovery model [PDF]

Journal of the Operational Research Society, 2019
Airlines require reserve crew to replace delayed or absent crew, with the aim of preventing consequent flight cancellations. A reserve crew schedule specifies the duty periods for which different reserve crew will be on standby to replace any absent crew.

Improving Crew Overboard Recovery for Commercial Fishing in the Gulf of Mexico

Journal of Agromedicine, 2023
Occupational fatality rates in the commercial fishing industry in the United States remain more than 20 times higher than the national average. The burden of commercial fishing fatalities due to unintentional falls overboard is highest in the Gulf of Mexico (GOM) shrimp fishery.

Spectral Clustering Approximation For Large Scale Crew Disruption Data Of An Airline Company For Intelligent Crew Recovery

Journal of Soft Computing and Decision Analytics, 2023
In the airline industry, after fuel costs, the crew costs con- stitute airlines’ second-highest cost items. For this reason, an airline needs to manage the valuable crew resource effi- ciently. Deviations from plans are fact in airline business and fixing deviations from crew schedules that occurred during operations by minimizing the crew-related ...

Aviation Crew Recovery Experiences on Outstations

Transport and Aerospace Engineering, 2016
Abstract ACMI flight crews spend considerable time away from home on outstations. This study suggests that this long term stay carries its own considerations in regards to rest recovery with practical implications for Fatigue Risk Management as prescribed by ICAO.
