Bus crew scheduling using mathematical programming
This thesis describes a bus crew scheduling system, IMPACS, which has been demonstrated to be successful for a wide variety of scheduling conditions, and is at present in regular use by three British bus companies including the largest, London Buses Ltd. The background to the bus crew scheduling …

Disruptions and Robustness in Air Force Crew Scheduling
Air Force crew scheduling involves assigning pilots to flights to fulfill mission duties and complete training requirements. Because of complex qualification requirements, as well as crew rest and availability constraints, Air Force crew scheduling is a challenging combinatorial optimization …

Air Force Crew Scheduling: An Integer Optimization Approach
Air Force flight, training, and crew scheduling is a labor-intensive and largely manual process across all flying squadrons. Complex training requirements and dependencies, operational constraints, numerous qualifications, and unforeseen missions confound the schedule development process. We …

Weekly crew scheduling for freight rail engineers : a network approach
… aims to design robust weekly schedules for these crew members to alleviate the pressures associated with irregular and unpredictable work hours. The scheduling problem is formulated as a multi-commodity network flow problem on a directed time-space graph. Both the two-city and three-city cases are …

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling
… costs by managing their flights, aircraft, and crews effectively. This motivates the extensive use of analytical techniques to solve complex problems related to airline operations planning, which includes schedule design, fleet assignment, aircraft routing, and crew scheduling. The initial …

Facility/infrastructure Resource Scheduling
… devices, would allow near-optimal, dynamic crew scheduling. In addition to construction scheduling, the FIRS approach can directly assist disaster recovery and reconstruction planners and those in other time-sensitive dispatching domains.

Evolutionary algorithms for scheduling operations
… and processes, operations such as job and crew scheduling are still performed manually in the majority of workplaces. The linear programming techniques are not capable of automated production of a job or crew schedule within a reasonable computation time due to the massive sizes of …

Scheduling Strategies for Bus Operator Retention: A Mixed-Methods Evaluation of Bus Operator Preferences and 4-Day Workweek Feasibility
… work is significantly impacted by inflexible crew scheduling constraints. However, most studies focus on pay, benefits, and infrastructure, neglecting the importance of scheduling. This thesis aims to fill this gap by examining the potential for crew scheduling improvements to enhance the …

Decision support for the operational planning phase of the transit network planning problem
… interdependent sub-problems, such as the vehicle scheduling problem (VSP), the crew scheduling problem (CSP), and the crew rostering problem (CRP). While various mathematical models are available for integrating these problems, the general failure to incorporate staff transportation requirements …

Robust airline schedule planning : review and development of optimization approaches
… assignment, aircraft maintenance routing and crew scheduling. Almost all aircraft and crew schedule optimization models assume that flights, aircraft, crews, and passengers operate as planned. Thus, airlines typically construct plans that maximize revenue or minimize cost based on the …

Evaluating the robustness of crew schedules for rail transit systems
Crew scheduling has traditionally been the last step in the process of service planning, and it has traditionally aimed at minimizing manpower costs because it was assumed that the crew schedule does not directly impact service quality. There has been a growing recognition that crew schedules do in …

Learning-based Scheduling
… for representing a wide range of real-world scheduling problems. Despite their ability to model general scheduling problems, solving large-scale integer programs (IP) remains a computational challenge in practice. The incorporation of more complex objectives such as robustness to disruptions …

Integrated Aircraft Fleeting, Routing, and Crew Pairing Models and Algorithms for the Airline Industry
… allocating their resources of aircraft and crews so as to reduce operational costs. In practice, this is achieved based on demand forecasts and resource availabilities through a structured airline scheduling process that is comprised of four decision stages: schedule planning, fleet …

Discrete Two-Stage Stochastic Mixed-Integer Programs with Applications to Airline Fleet Assignment and Workforce Planning Problems
… itinerary-based demand. Because certain related crew scheduling regulations require early information regarding the type of aircraft serving each flight leg, the current practice adopted by airlines is to solve the fleet assignment problem using estimated demand data 10-12 weeks in advance of …
