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, 2010
This 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

Verification and Validation Plan of Flight Performance Requirements for Human Crewed Spacecraft Parachute Recovery Systems

21st AIAA Aerodynamic Decelerator Systems Technology Conference and Seminar, 2011
The Crew Exploration Vehicle Parachute Assembly System (CPAS) is engaged in a multi-year design and test campaign aimed at qualifying a parachute recovery system for human use on the Orion Spacecraft. Orion has parachute flight performance requirements that will ultimately be verified through the use of Monte Carlo multi-degree of freedom flight ...

Solid waste management and resource recovery during the 4-crew 180-day CELSS integrated experiment

Life Sciences in Space Research
In order to explore the management and treatment methods of solid waste in the Controlled Ecological Life Support System (CELSS) of future lunar bases, during the 4-crew 180-day integrated experiment, the Solid Waste Management and Treatment System (SWMTS) was built, in which the treatment of recyclable solid waste such as inedible plant parts and ...

Crew and aircraft recovery through a multi-agent airline electronic market

2006
Airline 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.
