OBJECTIVES To study crew sick leave aboard and medical sign-off during one year (2004) among crew on a passenger ship doing worldwide cruising. Methods - Patient data were registered continuously during the year and reviewed afterward. RESULTS There was an average of 612 crew members (22% women) aboard. There were 6378 recorded crew visits (=17.5 per day), 3705 of which directly involved the ...
Job is one of the most important issues in the discussion of human resources, and since the discussion of job stress in the flight crew and its relationship with the performance of the flight crew is very important and vital. This research is about recognizing and developing a model for job stress among the cabin crew of Mahan Airline. The qualitative research methodology has been followed by q...
Operational use of high speed crafts (HSC)s may lead to physical harmful effects on crew and as a result, performance reduction will be anticipated. The purpose of current research is a human factors analysis in the HSCs. In this paper, First we recognized the crew ergonomic difficult in an Iranian sea organization by a field survey (whit collaborate of 57 crew). Validity and reliability of res...
A fermion realization of compact symplectic algebra provides a natural framework for studying pairing correlations of many-body interactions in nuclei. Here, we use quantum deformation concept in order to describe pairing correlations in atomic nuclei. While the nondeformed limit of the theory provides a reasonable and overall description of certain nuclear properties and fine structure effects...
We present a Lagrangian-based heuristic for the well-known Set Covering Problem (SCP). The algorithm was initially designed for solving very large scale SCP instances, involving up to 5,000 rows and 1,000,000 columns, arising from crew scheduling in the Italian Railway Company, Ferrovie dello Stato SpA. In 1994 Ferrovie dello Stato SpA, jointly with the Italian Operational Research Society, org...
This paper discusses a decision support system for airline and railway crew planning. The system is a state-of-the-art branch-and-price solver that is used for crew scheduling and crew rostering. We briefly discuss the mathematical background of the solver, of which most part is covered in the Operations Research literature. Crew scheduling is crew planning for one or a few days that results in...
Crew members on cruise ships are hired in a global labor market, and a major cost for cruise lines is moving crewmembers from their home cities to the cruise ship’s departure port. Complicating the crew scheduling problem is the uncertainty due to no-shows, terminations, and other reasons for crew to terminate their contract prematurely. To address this problem, this paper describes a schedulin...
