A military effectiveness analysis and decision making framework for naval ship design and acquisition

Hootman, John C. (John Christian), 1979- January 2003 (has links)
Thesis (S.M. in Naval Architecture and Marine Engineering; and, S.M. in Ocean Systems Management)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2003. / This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. / Includes bibliographical references (p. 93-100). / This research develops a new framework for performing military effectiveness analyses and design tradeoff decisions. It provides an extensive survey of literature for effectiveness analysis and multi-criteria decision making to develop a single consistent philosophy for such analyses. This philosophy is applied to a requirements and effectiveness analysis case study of a conventional submarine that is performed using Response Surface Methods to facilitate design space visualization and decision maker interaction. Measures of Merit are developed and applied to the case study. The resulting requirements space and methods to visualize and explore it in a decision making context are presented and discussed Lastly, a framework is proposed that would facilitate the concurrent consideration of requirements and effectiveness analyses with design and technology forecasting to create a Unified Tradeoff Environment that would provide decision makers with pertinent information to facilitate better informed requirements derivation and design selection. / by John C.

Legacy Computing Markup Language (LCML) and LEGEND -- LEGacy Encapsulation for Network Distribution / LEGEND

Geiger, Stephen Kurt January 2004 (has links)
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2004. / Includes bibliographical references (p. 131-133). / The rapid increase of computing power and emergence of distributed computing technologies such as Grid computing create new opportunities for scientific computing. One of the challenges faced in harnessing the emerging computational power is how to effectively use traditional command-line driven "legacy" codes within a networked framework; and a related challenge is how to make the operation of such codes a more user-friendly process. In this work a specification for an XML-based Legacy Computing Markup Language (LCML) is developed. This language can be used to create a parametized encapsulation of command-line driven codes and their associated files. Such an encapsulation can then be viewed and edited with a program developed to process LCML descriptions. The program LEGEND (LEGacy Encapsulation for Network Distribution) is under development as a Java implementation of such a program. LEGEND demonstrates that a validating graphical user interface can automatically be generated from an LCML description. Some issues related to the encapsulation of legacy programs and use of LCML and LEGEND are discussed, as well as the possibilitites for the integration of these technologies with Sun Grid Engine (SGE) and Globus software. / by Stephen Kurt Geiger. / S.M.

Responses of floating wind turbines to wind and wave excitation

Lee, Kwang Hyun January 2005 (has links)
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2005. / Includes bibliographical references (leaf 55). / The use of wind power has recently emerged as a promising alternative to conventional electricity generation. However, space requirements and public pressure to place unsightly wind turbines out of visual range make it desirable to move large wind farms offshore and into deeper coastal waters. A necessary step for the deployment of wind turbines into deeper waters is the development of floating platform systems. This thesis will present a general technical description of two concept designs for floating wind turbine systems, and make a preliminary evaluation of their performance in wind and waves. A new approach to computing the nonlinear wave excitation is also presented. / by Kwang Hyun Lee. / S.M.
