The progressive integration of automation technologies in commercial transport aircraft flight decks -the “glass cockpit” -has had a major, and generally positive, impact on flight crew operations. Flight deck automation has provided significant benefits, such as economic efficiency, increased precision and safety, and enhanced functionality within the crew interface. These enhancements, howeve...

Limitations that humans impose on task execution are rarely integrated into simulations of complex systems, often resulting in loss of outcome fidelity. In this paper we discuss how discrete-event simulation has been used to model the impact of human interactions in U.S. Navy and Coast Guard programs. These models of planned U.S. Navy and U.S. Coast Guard vessels have been used to estimate crew...

We propose a branch-and-price algorithm to solve the integrated multidepot vehicle and crew scheduling problem. An integer mathematical formulation that combines a multicommodity network flow model with a set partionning model is presented. We solve the corresponding linear relaxation using a column generation scheme. Two branching strategies are tested over benchmark instances available in the...

Timely detection and response to catastrophic events during the launch and ascent phase of the Ares I launch system is of paramount importance to crew safety. This requires an abort system capable of detecting and confirming conditions that may lead to catastrophic failure, notifying the crew of the problem, and responding in time to allow the crew to escape safely. The Ares I Abort Failure Det...

The late detection of the kick (the entrance of underground fluids into oil wells) leads to oil well blowouts. It causes human life loss and imposes a great deal of expenses on the petroleum industry. This paper presents the application of adaptive neuro-fuzzy inference system designed for an earlier kick detection using measurable drilling parameters. In order to generate the initial fuzzy inf...

AIM The aim of this study was to describe and compare the self-assessed occupational health among female nurses, cabin crew and teachers, in relation to their working environment. BACKGROUND Similarities between the three occupations, i.e. predominantly female and service-oriented, render them interesting in comparison with respect to health and working environment. METHODS The participants...

There are quite a few solutions for crew scheduling, including some commercial applications. The same happens for aircraft scheduling and for flight scheduling including revenue management. However, the airline operations problem did not receive the same attention as the other airline scheduling problems. In this paper we introduce this problem and report the work we are doing in the developmen...

The number of crew members in commercial flights has decreased to two members, down from the five-member crew required 50 years ago. One question of interest is whether the crew should be reduced to one pilot. In order to determine the critical factors involved in safely transitioning to a single pilot, research must examine whether any performance deficits arise with the loss of a crew member....

The integrated vehicle-crew-roster problem with days-off pattern aims to simultaneously determine minimum cost vehicle and daily crew schedules that cover all timetabled trips and a minimum cost roster covering all daily crew duties according to a pre-defined days-off pattern. This problem is formulated as a new integer linear programming model and is solved by a heuristic approach based on Ben...
