Optimal allocation is one of the most active research areas in operation research using binary integer variables. The allocation of multi constrained projects among several options available along a given planning horizon is an especially significant problem in the general area of item classification. The main goal of this dissertation is to develop an analytical approach for selecting projects that would be most attractive from an economic point of view to be developed or allocated among several options, such as in-house engineers and private contractors (in transportation projects). A relevant limiting resource in addition to the availability of funds is …
Identifying And Prioritizing Critical Success Factors For Fixed Base Operators In The United States: A Mixed Method Approach, Yu Wang
Open Access Dissertations
Fixed Base Operators (FBOs) are major service providers for the general aviation (GA) sector, which closely connect the public with the aviation industry. However, over the past decade, the U.S. GA industry has experienced a decline in the numbers of registered aircraft, pilots, and airports. Due to the fact that FBOs significantly contribute to the aviation industry, further research studies regarding the FBO-sector at a national level are needed. The purpose of this dissertation was to identify and prioritize the critical success factors (CSFs) that promote the success of FBO operations in the United States.

Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock
Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock
Senior Honors Theses
This thesis examines the movement of environmentalism, and its impact on architecture and construction. During an interview with a professional architect, a basis for research of sustainable design was devised, when he explained that “good” architecture attempts to holistically integrate the external and built environment. Presently, the main measurement for sustainability is energy efficiency. Therefore, architects constantly implement new technology in an attempt to unify both the external and built environment in an energy efficient manner. Furthermore, this thesis provides an environmental and financial cost analysis of implementing sustainable design and build. Research shows that the life cycle and up-front …

Civil Engineer Company Grade Officer Training Needs Analysis For Contingency Operations, Brian S. Greszler
Theses and Dissertations
In terms of active duty personnel, the USAF is the smallest it has ever been since its creation in 1947. With fewer personnel to accomplish essential tasks, the training of Airmen is more important than ever. Outdated and irrelevant training can lead to gaps in the knowledge of trainees. The purpose of this research was to analyze the training needs of Civil Engineer (CE) Company Grade Officers (CGOs) in the contingency environment. This was done by first conducting a Job Analysis (JA). The JA resulted in a list of 36 critical tasks and 58 important Knowledge, Skills, and Abilities (KSAs). …
The Welfare Effects Of Nationalization In A Mixed Duopoly Public Transport Market, Feifei Qin, Xiaoning Zhang, Eoin Plant
The Welfare Effects Of Nationalization In A Mixed Duopoly Public Transport Market, Feifei Qin, Xiaoning Zhang, Eoin Plant
Articles
Recently, many cities have launched new rail transit lines. Once these new rail transit lines start commercial operation, they will play important roles as competitors to conventional bus services. In this paper, the effects of nationalization on equilibria have been studied in a mixed duopoly public transport market, in which one publicly-owned rail transit operator competes with one private bus operator. Two numerical case studies show the nationalization of a rail transit company is always socially desirable both in Bertrand pricing game in the short run and in Nash non-cooperative game in the long run.

Project Risk Propagation Modeling Of Engineering, Procurement And Construction, Alireza Atin
Wayne State University Dissertations
The construction industry is complicated since it involves a variety of stakeholders, challenging environmental issues, huge investments, complex economic and political factors, and other features which may cause an uncertain and unpredictable environment for construction projects. Impacts of risk events can transfer from one phase (source) of a construction project to another phase (target) very quickly and can cause more damage in other phases. Thus, two surveys were conducted to understand the risk propagation phenomena among the engineering, procurement, and construction phases. We conducted two surveys and analyzed data acquired by using sensitive analysis and binary logistic regression modeling. Risk …
