Large-Scale Airline Crew Recovery Using Mixed-Integer Optimization and Supervised Machine Learning
Transportation ScienceAirlines take a variety of actions to recover schedules of their aircraft, crew, and passengers from operational disruptions. Aircraft are typically recovered first, followed by crew recovery, and then passenger recovery. This paper aims to repair disrupted crew schedules while ensuring the feasibility of previously decided aircraft recovery plans and ...

AbstractThe StratEx program used a self-contained space suit and balloon system to loft pilot Alan Eustace to a record-breaking altitude and skydive from 135,897 feet (41,422 m). After releasing from the balloon and a stabilized freefall, the pilot safely landed using a parachute system based on a modified tandem parachute rig.

Journal of Modelling in Management, 2022
Purpose Airline scheduling is an extremely complex process. Moreover, disruption in a single flight may damage the entire schedule tremendously. Using an efficient recovery scheduling strategy is vital for a commercial airline. The purpose of this paper is to present an integrated aircraft and crew recovery plans to reduce delay and prevent delay ...

Tree Crew Perspectives on Wood Product Recovery from Utility Vegetation Management
Arboriculture & Urban Forestry, 2020Utility vegetation management generates large quantities of wood that require disposal. To explore opportunities for reducing wood waste and promoting wood recovery, we evaluated the perceptions and experiences of utility-contracted tree crews regarding a wood recovery program.

Optimal airline crew recovery considering flight time constraint and paring rule
Proceedings 2011 International Conference on Transportation, Mechanical, and Electrical Engineering (TMEE), 2011This article has proposed a crew recovery methods based on previous researches. After taking into account of the current assignment and other rules, we created a mathematical model to solve this problem. As we can determine the scope of the crew recovery, lingo solver is more convenient.

Inter-Fleet and Intra-Fleet Models of Pilot and Flight Attendant for the Crew Recovery Problem
2010 International Conference on E-Product E-Service and E-Entertainment, 2010This paper investigates the intra-fleet and inter-fleet model for the solution of crew scheduling problem during airline irregular operations. The intra-fleet model is widely adopted in the airline industry where flight is grouped together and works typically within a fleet. The inter-fleet model on the other hand, splits of flight attendant groups and

The Civil Aviation Crew Recovery Time-Space Network Model Based on a Tabu Search Algorithm
2017In order to reduce cost of airlines when disruption of crew scheduling happens, a mathematical programming model of crew scheduling recovery is constructed under the usage of airline crew. In the proposed model, the objective is to minimize the usage of airline crew,moreover, the estimated delay costs are considered as chance constraints.

Crew and aircraft recovery through a multi-agent airline electronic market
2006Airline companies do not collaborate when dealing with problems that arise during their own operational control plan. These problems are related with aircrafts, crew members and passengers and the actions towards the solution of these problems are usually known as operations recovery.
