The Perception Of Travel Agents As To Passenger Acceptance Of The High Speed Civil Transport In Commercial Airline Service: A Study Of Tomorrow's Transpacific Air Travel, James H. Starnes Iii Dec 1993

The Perception Of Travel Agents As To Passenger Acceptance Of The High Speed Civil Transport In Commercial Airline Service: A Study Of Tomorrow's Transpacific Air Travel, James H. Starnes Iii

Master's Theses - Daytona Beach

Through a cooperative effort between NASA, Boeing Commercial Airplane Group, Douglas Aircraft Company, GE Aircraft Engines, and Pratt & Whitney, technology for a new-generation supersonic transport aircraft is being developed. To determine if air travelers will choose this aircraft, the High Speed Civil Transport (HSCT), as their mode of air transportation on transpacific routes, a self-developed questionnaire was sent to randomly selected travel agents in the Los Angeles, California area. The questionnaire examined criteria that passengers use to select transpacific flights, including fare, schedule, flight time length, and comfort. Results indicated that all passengers will be attracted to supersonic air …

Demonstration Of Improved Software Support Labor Estimation For Air Force Operational Flight Programs Through Functional Orientation, Ronald R. Warner Jr., Darrel L. Wright Dec 1993

Demonstration Of Improved Software Support Labor Estimation For Air Force Operational Flight Programs Through Functional Orientation, Ronald R. Warner Jr., Darrel L. Wright

Theses and Dissertations

This study demonstrated two approaches to improve current software support effort estimation models for aircraft software. Both approaches involved a functional orientation not used by existing models. The first approach demonstrated how to orient a model to reflect the block change cycle modification process and how to represent support effort changes over time in order to improve effort estimation accuracy. Current software models do not reflect the support environment or the temporal characteristics of aircraft software support. The second approach demonstrated how to calibrate a model by properly selecting source data in order to increase accuracy. Support calibration is not …

An Evaluation Of Aircraft Maintenance Performance Factors In The Objective Wing, Mark A. Gray, Margaret M. Ranalli Sep 1993

An Evaluation Of Aircraft Maintenance Performance Factors In The Objective Wing, Mark A. Gray, Margaret M. Ranalli

Theses and Dissertations

Prior to 1992, organizational maintenance was aligned under a - separate maintenance organization. In 1992, the Air Force restructured into Objective Wings with organizational maintenance aligned under the flying squadrons. This study looks at the impact of this reorganization on maintenance performance factors. The researchers developed maintenance performance models using regression and principal component analysis. Mission Capable Rate and Total Not Mission Capable Maintenance Rate are used as dependent variables. A comparison of key maintenance performance indicators and model predictions before and after the reorganization is accomplished. Based on the results of this analysis, the researchers conclude that there is …

An Econometric Analysis Of The Nw/Klm Corporate Alliance, S. Koo Boon Aug 1993

An Econometric Analysis Of The Nw/Klm Corporate Alliance, S. Koo Boon

Master's Theses - Daytona Beach

This thesis investigates whether a corporate alliance between international air carriers is beneficial, considering the changes in the global air transport system. Dividing the research method into three phases, the author first lists and identifies the recent changes in world air transport trends. Then, the author defines the different types of alliances and studies the advantages and disadvantages of these corporate alliances. Finally, a multiple regression analysis is performed using the KLM/Northwest Airlines alliance as a case analysis.

Scheduling Air Mobility Command's Channel Cargo Missions, Gregory S. Rau Mar 1993

Scheduling Air Mobility Command's Channel Cargo Missions, Gregory S. Rau

Theses and Dissertations

Through the use of a linear programming model, this research revised the initial schedule for AMC's channel cargo missions to eliminate any excess delay enroute by minimizing the cumulative, weighted time-in-system for all cargo, according to a given cargo flow. In fact, the revised schedule minimizes any assigned nonnegative weighting of the time-in-system, due to the properties of equivalent measures of performance. When combined with Step One of a proposed two-step process for revising AMC's channel mission schedule, this research can be used to improve the current schedule based on Step One's cargo flow. By carefully defining the notation and …

The Use Of Simulation To Evaluate Strategic Aeromedical Evacuation Policy And Planning, Charles W. Wolfe Jr. Mar 1993

The Use Of Simulation To Evaluate Strategic Aeromedical Evacuation Policy And Planning, Charles W. Wolfe Jr.

Theses and Dissertations

Strategic aeromedical evacuation (AE) of casualties from the theater of operations to the CONUS during wartime is a complex operation that involves the integration of medical personnel and policies with airlift concepts and capabilities. Military analysts within the Air Mobility Command Analysis Group (AMC/XPY) have traditionally used deterministic linear programming techniques to estimate the number of aircraft the United States Air Force (USAF) requires for given contingency scenarios. However, this group has yet to develop a stochastic approach to validate their resource recommendations, and more importantly, to study the interrelationships between key factors comprising strategic aeromedical evacuation. As the possibility …

Patient Scheduling And Aircraft Routing For Strategic Aeromedical Evacuation, Michael J. Loftus Mar 1993

Patient Scheduling And Aircraft Routing For Strategic Aeromedical Evacuation, Michael J. Loftus

Theses and Dissertations

The objective of this study is to develop an approach that would assign patients to aeromedical evacuation aircraft and route each aircraft to a single CONUS airport. The goal is to minimize total patient wait time. A heuristic algorithm is developed which exploits the structure of the problem. The first subproblem solved is the assignment of aircraft to airports. This subproblem is solved using integer programming and the results are input into the second subproblem. The second subproblem is the patient to aircraft assignment problem. This subproblem minimizes patient wait time and is solved using network flow programming. The two …

Models For The Optimization Of Air Refueling Missions, Clayton H. Pflieger Mar 1993

Models For The Optimization Of Air Refueling Missions, Clayton H. Pflieger

Theses and Dissertations

This research follows A. Yamani's work on the problem of minimizing total fuel costs for airlift missions that require in-flight refueling. Yamani's major assumptions were removed and the resulting enhanced formulation was applied the the original problem and the related problem of maximizing allowable cabin load. This optimization is accomplished selecting the rendezvous point and initial fuel for each aircraft. The formulation considers a C-141B airlifter refueled once by a KC-135E tanker. Flight is assumed to be at constant altitude and follow great-circle routes. The fuel costs of climb and cruise flight are modeled as functions of gross weight, while …
