Current society develops faster and faster every day with customers' demands increasing rapidly. Decreasing time for product development and enhancing customer satisfaction are becoming more significant. In the business world, there is no industry that could exist without an efficient supply chain. In the fierce competitive environment of today, the supply chain must address potential problems and risks that may exist and assure continuous improvement.

One common supply chain management practice in many industries is to apply lean methodology to the supply chain model in order to maximize the customers' value and eliminate waste. By eliminating waste, the process can …

Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler

Stephan Manning

This article examines how multinational corporations (MNCs) shape institutional conditions in emerging economies to secure access to high-skilled, yet lower-cost science and engineering talent. Based on two in-depth case studies of engineering offshoring projects of German automotive suppliers in Romania and China we analyze how MNCs engage in ‘active embedding’ by aligning local institutional conditions with global offshoring strategies and operational needs. MNCs thereby contribute to the structuration of field relations and practices of sourcing knowledge-intensive work from globally dispersed locations.Our findings stress the importance of institutional processes across geographic boundaries that regulate and get shaped by MNC activities.

A Mechanism Design Approach To Bandwidth Allocation In Tactical Data Networks, Ankur Mour

Open Access Theses

The defense sector is undergoing a phase of rapid technological advancement, in the pursuit of its goal of information superiority. This goal depends on a large network of complex interconnected systems - sensors, weapons, soldiers - linked through a maze of heterogeneous networks. The sheer scale and size of these networks prompt behaviors that go beyond conglomerations of systems or `system-of-systems'. The lack of a central locus and disjointed, competing interests among large clusters of systems makes this characteristic of an Ultra Large Scale (ULS) system. These traits of ULS systems challenge and undermine the fundamental assumptions of today's software …

Measuring Changes In International Production From A Disruption: Case Study Of The Japanese Earthquake And Tsunami, Cameron A. Mackenzie, Joost R. Santos, Kash Barker

Cameron A. MacKenzie

The earthquake and tsunami that struck Japan on March 11, 2011 caused a tremendous loss of life and property. The disaster also disrupted global supply chains, which was blamed for anemic growth in the global economy. A multiregional input-output model can quantify the international impacts on production due to changes in demand from companies reducing their orders because of a disruption. Using the input-output model to conceptualize a supply chain, we present a unique method for calculating indirect production losses caused by disabled production facilities. Methods for calculating the possible transfer of demand to industries in other countries are also …

Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha

USF Tampa Graduate Theses and Dissertations

Cap-and-trade is the most discussed CO₂ emissions control scheme in the U.S. It is a market-based mechanism that has been used previously to successfully reduce the levels of SO₂ and NO_x emitted by power generators. Since electricity generators are responsible for about 40% of the CO₂ emissions in the U.S., the implementation of CO₂ cap-and-trade will have a significant impact on electric power generation systems. In particular, cap-and-trade will influence the investment decisions made by power generators. These decisions in turn, will affect electricity prices and demand. If the allowances (or emission permits) created by …

The Effects Of Congressional Elections On Future Equity Market Returns, Vincent Louis Ovlia, David Lee Enke, Michael C. Davis

Engineering Management and Systems Engineering Faculty Research & Creative Works

As the primary entity responsible for new legislation, Congress is capable of enacting legislation that may affect future market returns. To examine potential effects, the percentage of the House of Representatives and Senate controlled by a political party is examined. Additionally, the effect on returns in a change in the percentage of seats gained or lost in Congressional elections is analyzed. To test both theories, a modified “partisan view” model is adopted. Results point to the fact that equity markets perform better in situations in which power is distributed between political parties.

Previous study has identified decision variables and throughput simulation models of port operation. However, none of these models have been utilized to investigate port's recovery from a security disruption and in evaluating recoverability investments. The method of research includes analysis of recorded disruptions, identification of impediments to recovery and investment criteria for recoverability. This article provides managers insight into including security and continuity of operation in managing various types …

Using Value-Focused Thinking To Evaluate The Effectiveness Of Air Force Utility Privatization, Carlos Braziel

Theses and Dissertations

The majority of the Air Force s stateside utility systems are old, obsolete, and unreliable. The cost to upgrade and repair these systems is currently estimated at over $4 billion. In response, the Air Force began efforts to convey ownership of these utility systems to the private sector through privatization efforts. However, privatization critics believe that newly privatized entities of government will cost the public more money and provide a lower level of service. Therefore, independent audits are a necessity to ensure government initiatives, meet their intended goals. However, the Air Force currently lacks an effective auditing tool to ensure …

Approximation Model Building For Reliability & Maintainability Characteristics Of Reusable Launch Vehicles, Resit Unal, W. Douglas Morris, Nancy H. White, Roger A. Lepsch, Richard W. Brown

Engineering Management & Systems Engineering Faculty Publications

This paper describes the development of parametric models for estimating operational reliability and maintainability characteristics for reusable launch vehicle concepts, based on vehicle size and technology support level. A reliability and maintainability analysis tool (RMAT) and response surface methods are utilized to build parametric approximation models for rapidly estimating operational reliability and maintainability characteristics such as mission completion reliability. These models that approximate RMAT, can then be utilized for fast analysis of operational requirements, for lifecycle cost estimating and for multidisciplinary design optimization.

Telecommunications And Its Practical Application, Athol, Massachusetts, Center For Economic Development

Center for Economic Development Technical Reports

Rural areas have been experiencing a transition in their economic and social structure. Traditional industries such as agriculture, manufacturing, and resource extraction have been declining. The result has been a displacement of labor in rural areas and instability within rural economies. Upwards of three quarters of rural counties have experienced outmigration in the last decade. Per capita income in rural areas is only two-thirds that of their urban counterparts, and rural poverty rates exceed those in urban areas. Rural areas have traditionally considering how the quality of their education, health, and government services can be incorporated into their overall development …

Assisting Defense Conversion Technology Transfer Efforts. A Case Study Of Ohio's Miami Valley, Marissa C. Salvador

Theses and Dissertations

Major changes in the geopolitical environment and the social and economic needs of the United States have resulted in resources being shifted away from national defense. Although the expected decrease in defense spending should not be harmful in macroeconomic terms, it can be devastating locally. To mitigate the effects of the drawdown, individual states and local communities must search for ways to bolster their local economies. One avenue that can be pursued to enhance future economic growth is the transferring of technologies to the commercial sector. Intermediary organizations have emerged to facilitate the process of technology transfer by serving as …

Information Technology And Wealth: Cybernetics, History And Economics, Elin Whitney-Smith

Engineering Management & Systems Engineering Theses & Dissertations

Capitalism developed where and when it did because there was high information access. There was high information access because of a major advance in information technology--the press. Where the technology was not controlled by the "powers that be" there was economic growth and a shift in the entire social structure. Where it was controlled there was no structural change and there was economic ruin. The development of capitalism is a major step change in economic growth. It is also a major change in the way people organize themselves into groups.

Rebirth Of The Downtown Industrial District--Key To Revitalization, Chester Smolski

Smolski Texts

"Residents were there by the hundreds to welcome home one of their noteworthy product of a previous era. 'Old 299' had just returned from the Panama Canal Zone to its final resting place in the New Paterson Museum, a fitting climax for the 2-6-0 'Mogul' type steam locomotive that was born here in 1906. And June 6, 1979 marked the gala return of one of the few remaining American-made locomotives that were so instrumental in the construction of the Panama Canal by this nation in the period from 1904 to 1914, after earlier unsuccessful attempts by the French."

Economics And Net Energy Analysis: Is A New Analytical Technique Needed For Energy Decision Making?, William J. Kruvant

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The paper attempts to evaluate the claims of Net Energy Analysis (NEA) against those of economics in a reasonably comprehensive way. The principal problems of NEA concern system boundaries, aggregation across fuels, valuing external effects, valuing human labor and valuing time. These problems seriously limit the contribution Net Energy Analysis can make to allocation decisions, and allocation Is the central problem of energy policy.

The Impact Of Changing Net Returns On Minimum Energy Requirements For Grain Farms, James B. Kliebenstein, Robert M. Finley, Douglas C. Farthing

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

With sources of energy more restricted and higher priced, optimal combinations of enterprises must logically be considered on the basis of energy efficiency. One method of ascertaining this efficiency is to optimize solutions for given levels of income on the basis of energy used (e.g., the objective function was in terms of energy kilocalories). In general, soybeans were most feasible at lower levels of income regardless of farm size and labor circumstance. As income levels increased, double-cropping (wheat soybeans) was first substituted and finally corn at highest income levels.

Non-Cash Incentives And Worker Motivation, Daniel Franklin Cole

Masters Theses

"A problem of growing concern in the United States deals with the poor results of the nation's businesses in terms of productivity. The U.S. is now suffering the worst decline in productivity in a generation. While part of this decline can be attributed to economic conditions, data indicates that the labor force could be more productive if it wanted to do so. A study has shown that 52% of all workers feel they aren't producing at full capacity. Alienation of the American worker is identified as one of the most important contributors to this problem.

Because it is often difficult …
