Optimization-based decision support system for crew scheduling in the cruise industry

Crew members on cruise ships are hired in a global labor market, and a major cost for cruise lines is moving crew members 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 scheduling system that implements a two-stage planning process that first determines overbooking levels for the number of crew to offer contracts to, and then second, a goal integer programming formulation to minimize the movement cost of assigning crew to ships while maintaining adequate crew levels and a desired crew region composition. We solve actual-sized problems characteristic of the cruise industry in a reasonably short amount of time. Experiments comparing the actual crew movement costs to the system’s projected crew movement costs show that the scheduling system can consistently reduce the movement costs in the range of 9–23%, better maintain desired crew levels, and better maintain desired crew region composition.

An integrated logistics support system for training crew medical officers in advanced cardiac life support management.

The purpose of this paper is to present an approach for the development of an integrated logistics support system for training space flight crew medical officers in advanced cardiac life support (ACLS). The most practical approach to deal with this problem has been determined to be the training of one or more of the crew members on the mission as crew medical officers (CMO's). If this approach is taken, there are a number of problems that must be addressed. The basic approach presented in this paper is to develop a performance quality index for ACLS tasks and use this index to monitor and control the performance of crew members throughout their tenure as CMO's. The control tool of the system is based on an integrated learning and forgetting model used to forecast CMO performance level at a given point during flight training. The model represents an aid for trainers in determining a training regime and maintaining the performance standards. A performance evaluator and trainer is also developed to help in the establishment of trainee performance level during training or retraining. All of these tools were evaluated using either expert opinion questionnaires or experimental results. In conclusion, the results presented provide the tools required for an integrated logistics support system for training ACLS personnel.

Operational airline reserve crew planning

Airlines are continually faced with the challenge of efficient utilization of their cockpit crew resources. In addition to regular flying crews, some airlines have to maintain significant reserve staffing levels to meet contractual obligations and provide smooth daily operations. Reserve crews are required to cover trips remaining unassigned due to disruptions during daily operations. Airlines using a bidline system to award crew work schedules require additional reserves to cover scheduling conflicts, which result in trips dropping out of optimized bidlines. Whenever reserves are unavailable to cover these trips during daily operations, the airline has to pay a premium to cover these trips using regular pilots. The resulting operating expenses can be significant. Furthermore, inefficient utilization of reserves can cause excessive long-range crew staffing resulting in additional training and new hire expenses. In this paper, we propose a new optimization strategy to increase reserve crew utilization and build monthly reserve crew work schedules by addressing the issue of scheduling conflicts and daily operational reserve requirements.     

Models and Algorithms for Integration of Vehicle and Crew Scheduling

This paper deals with models, relaxations, and algorithms for an integrated approach to vehicle and crew scheduling for an urban mass transit system with a single depot. We discuss potential benefits of integration and provide an overview of the literature which considers mainly partial integration. Our approach is new in the sense that we can tackle integrated vehicle and crew scheduling problems of practical size.We propose new mathematical formulations for integrated vehicle and crew scheduling problems and we discuss corresponding Lagrangian relaxations and Lagrangian heuristics. To solve the Lagrangian relaxations, we use column generation applied to set partitioning type of models. The paper is concluded with a computational study using real life data, which shows the applicability of the proposed techniques to practical problems. Furthermore, we also address the effectiveness of integration in different situations.
