The Effects Of A Modified Gantt Chart Depicting Schedule Risk, Joseph Allen Hope

Computational Modeling & Simulation Engineering Theses & Dissertations

The tools and methodologies used to manage projects continue to evolve. A popular project management tool for monitoring a project's schedule is the Gantt chart. The Gantt chart provides information about projected start and end times for each task of a project. A critical limitation of the Gantt chart, however, is its inability to depict uncertainty surrounding the project schedule, or project schedule risk. The present study investigated the effectiveness of three alternative formats for depicting schedule risk. The three presentation formats used were a table, a table with a traditional Gantt chart, and a table and a modified Gantt …

Risk Perception Regarding Energy Production: Factor Structure In A French Sample, Etienne Mullet, Anne Bertrand, Cécilia Lazreg, Sheila Rivière Shafighi

The University of New Hampshire Law Review

[Excerpt] "Considering that energy production is a key factor in the development of nations, it is important to have detailed information on the risks attributed by lay people to the different types of energy as well as the different stages of energy production. This study reports on the structure of risk perception with regard to energy production found among French participants. There have already been many investigations of risk perception related to energy production. . . .

The present study is a direct extension of the Mullet study. A similar, although more complete, set of items was used. These items …

Co-Operation In Health And Safety: A Game Theory Analysis, Sylvie Nadeau

The University of New Hampshire Law Review

[Excerpt] “Health and safety managers face complex challenges in today’s production environments. They are confronted with increasingly flexible, autonomous and polyvalent contexts. Asymmetry of information on the workplace is widespread because various intervening parties rely on information lacking conformity. Social partners generate and use information which supports or benefits their pursuit of differing goals. Ascertaining and controlling this information can prove both difficult and costly. When addressing health and safety issues, one intervening partner alters or changes behavior in response to changes introduced by the other side. Strategic behaviors result, based on post-contract opportunism (moral hazard) and alliances with partners …

Estimating Engineering And Manufacturing Development Cost Risk Using Logistic And Multiple Regression, John V. Bielecki

Theses and Dissertations

Cost Growth in Department of Defense (DoD) major weapon systems has been an on-going problem for more than 30 years. Previous research has demonstrated the use of a two-step logistic and multiple regression methodology to predicting cost growth produces desirable results versus traditional single-step regression. This research effort validates, and further explores the use of a two-step procedure for assessing DoD major weapon system cost growth using historical data, We compile programmatic data from the Selected Acquisition Reports (SARs) between 1990 and 2001 for programs covering all defense departments. Our analysis concentrates on cost growth in the research and development …

Outsourcing Information Technology And The Insider Threat, Valerie L. Caruso

Theses and Dissertations

As one of our nation's top critical infrastructures, telecommunications is an essential element of many aspects of our lives upon which we, as a society, are becoming increasingly dependent. Computers, digital telephone switches, and interconnected information technology (IT) systems impact finances, travel, infrastructure management, and missions of national defense. This research examined whether the trend in increased outsourcing of information technology systems is a significant contributing factor to a reportedly increasing amount of insider attacks. In light of changing social, global economic, and technological conditions, the paradigm in which risk analysis, management practices, and operational and personnel security practices are …

The Air Force Operational Risk Management Program And Aviation Safety, Matthew G. Cho

Theses and Dissertations

Aviation mishaps are extremely costly in terms of dollar value, public opinion, and human life, The Air Force drastically reduced Class A mishap rates in its formative years. The rate plummeted from 44.22 mishaps per 100,000 flight hours in 1947 to 2.33 mishaps in 1983 and has held steady around 1.5 mishaps since. The Air Force implemented the Operational Risk Management (ORM) program in 1996 in an effort to protect their most valuable resources: aircraft and aviators. An AFIT thesis conducted in 1999 by Capt Park Ashley studied the Army similar Risk Management (RM) program. Ashley concluded that since his …

Development Of An Aggregation Methodology For Risk Analysis In Aerospace Conceptual Vehicle Design, Trina Marsh Chytka

Engineering Management & Systems Engineering Theses & Dissertations

The growing complexity of technical systems has emphasized a need to gather as much information as possible regarding specific systems of interest in order to make robust, sound decisions about their design and deployment. Acquiring as much data as possible requires the use of empirical statistics, historical information and expert opinion. In much of the aerospace conceptual design environment, the lack of historical information and infeasibility of gathering empirical data relegates the data collection to expert opinion.

The conceptual design of a space vehicle requires input from several disciplines (weights and sizing, operations, trajectory, etc.). In this multidisciplinary environment, the …
