This paper presents an approach for solving the bus crew scheduling problem which considers early, day, and late duty modes with time shift and work intensity constraints. Furthermore, the constraint with the least crew number of a certain duty e.g., day duty has also been considered. An optimization model is formulated as a 0-1 integer programming problem to improve the efficiency of crew sche...

Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportuni...

We propose, optimize and validate a methodological framework for estimating the extent of the crewpropagated delays and disruptions (CPDD). We identify the factors that influence the extent of the CPDD, and incorporate them into a robust crew scheduling model. We develop a fast heuristic approach for solving the inverse of this robust crew scheduling problem to generate crew schedules that are ...

This article reports on the wellness of selected cabin crew members at a South African airline. The aviation industry introduces a great amount of potential environmental stressors to cabin crew. The purpose of the research was to explore the wellbeing of cabin crew and the stressors related to their working environment. As primary safety officers on board an aircraft, cabin crew perform a vita...

An airline crew rostering problem is a large-scaled and complex optimization problem that assigns crew members to the flight duties while satisfying agreements with the labor union, the government regulations, the carrier’s own policies, and other requirements. The traditional crew rostering problem considers only minimizing the total perdiem in order to reduce the airline expense. This paper p...

The ability to generate crew pairings quickly is essential to solving the airline crew scheduling problem. Although techniques for doing so are well-established, they are also highly customized and require significant implementation efforts. This greatly impedes researchers studying important problems such as robust planning, integrated planning, and automated recovery, all of which also requir...

Delays occurring during a crew’s duty may propagate to subsequent tasks, leading to cancelation of certain trains in the worst case. Instead of the original crew, a move-up crew may take over the rest of the delayed crew’s duty, which is then on time. In this paper, we address both the problem of how to create robust crew schedules yielding many of such move-up crews, as well as the problem of ...

Few studies of cancer mortality and incidence among flight crew have included a detailed assessment of both occupational exposures and lifestyle factors that may influence the risk of cancer. In this issue, Kojo et al. (Risk factors for skin cancer among Finnish airline cabin crew. Ann Occup. Hyg 2013; 57: 695-704) evaluated the relative contributions of ultraviolet and cosmic radiation to the ...

Crew management is concerned with building the work schedules of crews needed to cover a planned timetable. This is a well-known problem in Operations Research and has been historically associated with airlines and mass-transit companies. More recently, railway applications have also come on the scene, especially in Europe. In practice, the overall crew management problem is decomposed into two...

Airline crew scheduling is a comparably well-studied field in Operations Research. An increasing demand for higher crew satisfaction arises; especially after most relevant cost factors have been optimized to their greatest extent, mostly with secondary or little regard on quality-of-life criteria for the involved crew members. One such criterion is team-orientation. Independent from the chosen ...
