Establishing A Benchmark Of Fuel Efficiency For Commercial Airline Operations, Samuel Chandra, Chetan K. Chitgopeker, Ben Crawford, John Dwyer, Yi Gao
Journal of Aviation Technology and Engineering
Fuel efficiency is vital for commercial airlines as fuel is one of the most costly items for airline operations. This study aims to compare fuel efficiencies of selected airlines around the globe and to build a benchmark of fuel efficiency that can be referred to by airlines. By using data on fuel consumption and traffic output collected from various sources including airline annual reports, environmental reports and sustainability reports, this study calculated fuel efficiencies measured by liters of fuel consumed per revenue tonne kilometer (RTK) for the selected airlines in the calendar year 2011 or financial year 2010–2011. Airlines ...

The Impact Of Budget Constraints On Flexible Versus Dedicated Technology Choice, 2014 Singapore Management University
The Impact Of Budget Constraints On Flexible Versus Dedicated Technology Choice, Onur Boyabatli, Tiecheng Leng, L. Beril Toktay
Research Collection Lee Kong Chian School Of Business
This paper studies the flexible-versus-dedicated technology choice and capacity investment decisions of a multi-product firm under demand uncertainty in the presence of budget constraints. The firm operates under a capital budget for financing the capacity investment, and an operating budget, which is uncertain in the capacity investment stage, for financing the production. We investigate how the tightening of the capital budget and a lower financial exibility in the production stage (the likelihood of having sufficient operating budget) shape the optimal technology choice. We find that the dominant regime is one where dedicated technology should be adopted for a larger investment ...
State Space Modelling Of Dynamic Choice Behavior With Habit Persistence, 2014 University of Tennessee, Knoxville
State Space Modelling Of Dynamic Choice Behavior With Habit Persistence, Kang Bok Lee
In this dissertation, I present a new approach to capturing dependence across time in dynamic choice data. To achieve this, I develop a state space dynamic choice model and a novel algorithm to fit the data. Instead of capturing dependence in outcomes through lagged response variables, referred to as state dependence, I introduce a lagged utility term through the latent state equation. The lagged utility term captures habit persistence, which has not been explored directly in earlier models (Heckman, 1981b). The autoregressive nature of the lagged utility provides a significantly richer summary of prior utility than a lagged outcome variable ...
Predicting The Uptake Of A University’S Offers Of Places, 2014 Kwantlen Polytechnic University
Predicting The Uptake Of A University’S Offers Of Places, Stephen Peplow
All Faculty Scholarship
Institutions such as Universities spend considerable resources in recruiting and following up on applicants. Unfortunately, much wastage results from the sending out of follow-up letters to students who never arrive, and who perhaps had applied only as a form of insurance; and also in hiring instructors and scheduling classes when the attendance is uncertain. In a competitive market, a predictive model of the uptake of offers made might well be helpful. Kwantlen Polytechnic Unviersity is featured in the article.

Assessing Customer Service In Airports – Models From The Uae, Aman Gupta, Mohammed Arif, Phillip A. Richardson
International Journal of Aviation, Aeronautics, and Aerospace
Customer service at airports has become a key priority for airport operators given the high degree of competitions. This paper uses an airport customer service model to analyze three examples from the United Arab Emirates (UAE). Passenger interviews, statistical information, customer feedback and other forms of information have been utilized to learn more about the customer view on the quality of service offered at these three airports. Detailed qualitative analysis of these case studies has highlighted some key issues in the area of customer service and identifies some opportunities for improvement.

Assortment Planning Of Automotive Products: Considerations For Economic And Environmental Impacts Of Technology Selection, Ali Taghavi, Ratna Babu Chinnam
Industrial and Systems Engineering Faculty Research Publications
A manufacturer’s assortment is the set of products that the company offers to its customers. Assortment planning considerably affects both the sales revenue and product offering costs for the company and it had experienced growing attention across different industries over recent decades. In this study, we propose a modeling framework that seeks to identify the optimal assortment for a manufacturer of configurable products (in particular, automobiles). Our model accounts for environmental considerations (Corporate Average Fuel Economy requirements, tail-pipe emissions, and greenhouse gas emissions related to the production of the fuel used to power the vehicle) during assortment planning. We ...

Indefinite Knapsack Separable Quadratic Programming: Methods And Applications, 2014 University of Tennessee, Knoxville
Indefinite Knapsack Separable Quadratic Programming: Methods And Applications, Jaehwan Jeong
Quadratic programming (QP) has received significant consideration due to an extensive list of applications. Although polynomial time algorithms for the convex case have been developed, the solution of large scale QPs is challenging due to the computer memory and speed limitations. Moreover, if the QP is nonconvex or includes integer variables, the problem is NP-hard. Therefore, no known algorithm can solve such QPs efficiently. Alternatively, row-aggregation and diagonalization techniques have been developed to solve QP by a sub-problem, knapsack separable QP (KSQP), which has a separable objective function and is constrained by a single knapsack linear constraint and box constraints ...

Elements Of The Nordic Leadership Framework, Origins, And Transferability, 2014 Syracuse University
Elements Of The Nordic Leadership Framework, Origins, And Transferability, Maggie H. Chen
Syracuse University Honors Program Capstone Projects
Leadership styles can be classified into different buckets based on previously developed leadership framework theories such as transformational, transactional, charismatic, and democratic leadership. This thesis explores the characteristics that define the Nordic style of leadership from a cross-cultural perspective. Under the assumption that the four Nordic nations: Denmark, Finland, Norway, and Sweden share a similar set of leadership practices, my capstone investigates the linkage between the Nordic national cultures and the influences on the leadership approach. The four small, but powerful nations are the homes to many corporations recognized for their highly innovative solutions to meet consumer needs. Nordic leaders ...
Segmenting Segmentation: A Taxonomy Bridging Theory And Practice Of Strategic Consumer Segmentation, 2014 Kennesaw State University
Segmenting Segmentation: A Taxonomy Bridging Theory And Practice Of Strategic Consumer Segmentation, Andrew Thomas Thoeni
Dissertations, Theses and Capstone Projects
Beginning with Chamberlin’s explanations of market variation in 1933, segmentation has been formally studied for eighty years. While more than 2,700 studies have been published (most as studies on statistical methods of segmentation), scant evidence has been gathered on the role market segmentation plays in strategy formulation and what has been presented has not been adequately classified to provide a basis for further comparative study. Based on Resource-Advantage theory, this dissertation defines a taxonomy of strategic segmentation that depicts how a firm’s view of a market relates to its assumed heterogeneity of the market and how a ...

Value Of Information Analysis: The State Of Application. Environment Systems & Decisions, 2014 University of Massachusetts Boston
Value Of Information Analysis: The State Of Application. Environment Systems & Decisions, Jeffrey Keisler, Eric Chu, Zachary Collier, Nina Sinatra, Igor Linkov
The value of information (VoI) is a decision analytic method for quantifying the potential benefit of additional information in the face of uncertainty. This paper reviews the prevalence of VoI applications reported in the peer-reviewed literature from the years 1990–2011. We categorize papers’ applications across the types of uncertainties considered, modeling choices, and contexts of social importance (such as health care and environmental science). We obtain and analyze statistics on the range of applications and identify trends and patterns in them, and conclude with an interpretation of what these mean for researchers and practitioners as they pursue new efforts ...

An Experimental Investigation Of Outsourcing Through Competition, 2014 University of Massachusetts Boston
An Experimental Investigation Of Outsourcing Through Competition, Ehsan Elahi, Roger Blake
Our research uses laboratory experiments to examine the theoretical results of competition between suppliers in an outsourcing setup. We consider a supply chain in which a single buyer needs to outsource the manufacturing of a product among N potential suppliers. The buyer allocates demand to suppliers not on the basis of price, but rather on service. We analyze the levels of service suppliers will decide to provide when competing on three different criteria specified by the buyer. For the first, suppliers compete by providing the buyer a specific service level (fill-rate), and for the second by maintaining a specific quantity ...
