The environment in which airlines operate is uncertain for many reasons, for example due to the effects of weather, traffic or crew unavailability (due to delay or sickness). This work focuses on airline reserve crew scheduling under crew absence uncertainty and delay for an airline operating a single hub and spoke network. Reserve crew can be used to cover absent crew or delayed connecting cre...

Airline crew scheduling is a very important part of the operational planning commercial airlines, but it linear integer programming problem with multi-constraints. Traditionally, airline determined by solving pairing (CPP) and rostering (CRP), sequentially. In this paper, we propose new heuristic solver based on parallel genetic algorithm an innovative algorithm, which improves traditional inte...

INTRODUCTION Crew familiarity, in terms of having recent operational experience together as a crew, is seen as an important safety-related variable. However, little evidence exists to unpack the underlying processes with respect to familiarity. This study investigated the relationships between crew familiarity, non-technical performance, and error management. METHOD Data were collected during...

Traditional methods model the billion-dollar airline crew scheduling problem as deterministic and do not explicitly include information on potential disruptions. Unfortunately, the effort used to optimize crew schedules and reduce crew costs is often wasted as flight schedules are often disrupted. Consequently, airlines spend a great deal of time and money optimizing crew schedules in the plann...

The crew scheduling problem in the airline industry is extensively investigated in the operations research literature since efficient crew employment can drastically reduce operational costs of airline companies. Given the flight schedule of an airline company, crew scheduling is the process of assigning all necessary crew members in such a way that the airline is able to operate all its flight...

STUDY OBJECTIVE To study crew referrals to out-patient port services from 3 passenger ships during 12 months (2004), with focus on dentist appointments. The median number of crew on Ship A was 561, on Ship B 534 and on Ship C 614. METHODS Crew referrals were registered continuously and after each cruise segment recorded in the ship's doctor's medical cruise report, from which the data were re...

Introduction “Camp Torpomoen” is an annual training camp for HEMS crew in Norwegian Air Ambulance. The main goal is to improve medical treatment of the sick and injured patient. To obtain this, the crew practice in Medical Simulation, team training in a patient scenario, creating realistic environments. The objective for this study was to observe and rate the non-technical skills of the crew in...

In some urban transportation companies driving periods are short when compared with the total duty time, leading to long non-driving periods that can be used as cover time. This paper presents the Crew Timetabling Problem, an extension of the Crew Scheduling Problem in which crew timetables are obtained by levelling the cover crew resources. An objective function for this problem is proposed in...

This study analyzes techniques instructor pilots (IPs) use to facilitate crew analysis and evaluation of LOFT performance. We analyzed IP facilitation and crew participation for 36 debriefing sessions conducted at five U.S. airlines. For this analysis we developed a rating instrument called the Debriefing Assessment Battery (DAB) and demonstrated that it can be used reliably. IP facilitation sk...
