Robust crew pairing : delays analysis and implementation of optimization approaches
… disturb airline operations, the development of robust schedules is becoming crucial. Increased traffic and poor weather are a few of the causes of airport congestion, rising delays and lengthening passenger trips. In this thesis, we identify the latest trend in the flight arrival and departure …

Disruptions and Robustness in Air Force Crew Scheduling
… pilot availability motivate the need for more robust schedules. Traditionally, this has been a manual, tedious, and time-consuming process. In this thesis, we leverage optimization techniques to improve the crew scheduling process. We start with a baseline integer program formulation. We …

Battery-Electric-Bus Transit System Design
… each charging configuration to find efficient robust schedules that can withstand the uncertainties of travel time and energy demand. Then, each scenario undergoes a single-charger failure simulation to assess the operational impact of energy supply disruptions. The simulation quantifies the …

Applications of Automatic Vehicle Location systems towards improving service reliability and operations planning in London
… (AVL) systems, have provided agencies with robust data collection and measurement systems and enabled the development of comprehensive planning and operations tools. This thesis reviews the impact of an AVL installation in London, and demonstrates how data recorded by this system may be used …

Design and Implementation of a Distributed Executive
… strategies to coordinate multiple robots’ schedules when communication is unreliable have been conservative, as they tend to favor prefixing the time for their actions, creating rigid and non-robust schedules. Such schedules can allocate excessive time to tasks as a safety measure, leaving …

A Systematic Framework for Machine Learning-Based Robust Project Scheduling Under Uncertainty
… project uncertainties and risks. Therefore, robust project scheduling approaches have been introduced to address this issue, through the incorporation of project buffers in the schedule. However, the majority of these approaches use arbitrary buffer sizing and allocation strategies which …

Weekly crew scheduling for freight rail engineers : a network approach
… long faced unpredictable and inflexible work schedules, leading to on-the-job fatigue, compromised safety and poor work-life balance. This paper aims to design robust weekly schedules for these crew members to alleviate the pressures associated with irregular and unpredictable work hours. The …

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling
… opportunities for passengers, hence yielding robust schedules while saving fleet assignment costs. A provision is also made for airlines to capture an adequate market share by balancing flight schedules throughout the day. Furthermore, demand recapture considerations are modeled to more …
