Analysis Of Aircraft Arrival Delay And Airport On-time Performance
While existing grid environments cater to specific needs of a particular user community, we need to go beyond them and consider general-purpose large-scale distributed systems consisting of large collections of heterogeneous computers and communication systems shared by a large user population with …

Analysis of airline schedule padding on U.S. domestic routes
… faces the risk of arriving late because flight times are subjected to many sources of variability. These can be weather conditions and airspace congestion, imbalances between airport demand and capacity, fleet and crew availability, technical failures and delays in maintenance, and other airline …

Coordination, Matchmaking, And Resource Allocation For Large-scale Distributed Systems
… delay were developed. The models use the Airline On-Time Performance Data from the Federal Aviation Administration (FAA) and the Surface Airways Weather Data from the National Climatic Data Center (NCDC). Multivariate regression, ANOVA, neural networks and logistic regression were used to detect …

Evaluating airline delays : the role of airline networks, schedules, and passenger demands
… a framework for analyzing airlines' operational performances under different strategic decisions. A detailed study is conducted to compare differences between a major U.S. legacy carrier and a major U.S. low-cost carrier in terms of their scheduling practices, flight-based delays and on-time …

The impact of Amtrak performance in the Northeast Corridor
The performance of Amtrak's Acela and Regional services in the Northeast Corridor (NEC) is a topic that, while frequently discussed as substandard by some travelers, has received minimal attention in the compendium of open source research literature. Amidst leading discussions in U.S. Congress to …

The Effect of Airport Delays on the Evolution of the U.S. Air Travel Network
An investigation is made into the question of how U.S. airlines respond to airport-based delays at domestic airports using data from the FAAs On-Time Performance database and aircraft inventories for major U.S. Airlines. Three delay mitigation techniques are studied: increasing aircraft size, …

Modeling end-to-end order cycle-time variability to improve on-time delivery commitments and drive future state metrics
… accelerating investments to simplify and improve one of the core competencies it was founded on, customer experience. One goal within this initiative is to increase the percentage of orders that are ontime to a committed Estimated Delivery Date (EDD). EDDs for products vary greatly with the …

A Multi-Objective Affinity-Based Savings Algorithm for Improving Processes in Centralized Warehousing Operations
<p>Traditional approaches to improving material management processes in warehousing operations tend to focus on one of three major areas: facility design, order picking and sorting, and order batching. In an effort to improve total system savings, a new affinity function is developed and applied to …

Incorporating traffic patterns to improve delivery performance
Traffic, construction and other road hazards impact the on-time performance of companies that operate delivery fleets. This study examines how incorporating traffic patterns in vehicle route development compares with standard, deterministic methods. We seek to understand how using historical data …

Empirical investigations of properties of robust aircraft routing models
… schedule planning process is an important component of airline operations, and it involves considerably complex problems. This research focuses on the aircraft routing phase. We introduce the concept of robustness in aircraft routing problems, and find solutions that can stand uncertainty. We …

Robust crew pairing : delays analysis and implementation of optimization approaches
With increasing delays and airport congestion that 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 …

Rethinking the hub and spoke airline strategy : an analysis and discussion of American Airline's decision to depeak its schedule at O'Hare International Airport
… that began in early 2000 was exacerbated not only by the terrorist attacks in the United States on September 11, 2001, but also by other pressures for strategic change. Continued growth and competition of low cost carriers coupled with changing purchasing habits of passengers have led industry …

Sustainable transport at MIT : improving area bus services
… each member of the MIT community makes a decision about how they will travel to school or work. Using the Commuter Habit Survey and information regarding local bus services as guides, this report analyzes the existing transportation options available to MIT students, staff, and faculty. People …

Affecting Change Synergistically: An Interpretative Case Study of Leadership Relationships at Southwest Airlines
… becomes increasingly more important to move beyond what we have come to know as leadership--great man and position/authority-based, excellent management. Instead, what organizations are in need of is a postindustrial model of leadership. Rost defined 21st century leadership as "an influence …

Designing new performance-based incentive regimes for operating contracts in the Province of Gipuzkoa, Spain
… world have introduced competitive bidding in concessions for providing bus service, often resulting in reduced costs for service. The main caveat to this approach is that without proper oversight by the authority, operators may reduce quality to cut costs and maximize profits. To counter this, …

The framework of direct and indirect effect of project risk response-related measures on project performance in managing construction delay
Project performance can be enhanced via proper risk management, particularly with the development of risk response measures. Though delay issues have been explored in many studies, to date, no study has attempted to measure how delay factors and risk measures are associated with the project …

Planning for robust airline operations : Optimizing aircraft routings and flight departure times to achieve minimum passenger disruptions
Airlines typically construct schedule plans based on the assumption that every flight leg departs and arrives as planned. Because this optimistic scenario rarely occurs, these plans are frequently disrupted and airlines often incur significant costs in addition to the originally planned costs. …

Essays in industrial organization
This thesis consists of three empirical essays in industrial organization. The first chapter examines the welfare effects of intertemporal price discrimination in market for airfare using a novel structural model of dynamic consumer search. I model how consumers search for airline tickets over time …

Forecasting linehaul transit times & on time delivery probability using quantile regression forests
with delays on the road and variabilities introduced by the major participants in the process, ie: distribution centers, drivers, etc. These sources of variability also make it difficult to measure the impact changes in transit time have on on-time performance. This paper focuses on trying to …

Estimating the true extent of air traffic delays
… been adjusted to take into account airspace congestion and yield better on-time performance. In that context, delay measures that are using scheduled times as a benchmark are of very limited use in assessing airport and airspace system congestion, since delay has already been built into the …
