Abstract
The 1990 Naval Sea Systems Command Ship Design, Acquisition and Construction (DAC) Study provides a stepping stone for the implementation of improvements towards optimizing ship performance, cutting acquisition costs,andreducingdesigncycletime. Withrespecttoperformance,significantadvancesincomputingpower coupled with customer oriented design (QFD, AHP. evolutionary optimization, etc) provide both improvements and direct means to measure effectiveness of improvements. As for cost, implementation of world class building and design techniques (concurrent engineering, group technology. CAD/CAM/CAE. etc) coupled with higher fidelity costingmethods(ACEIT.PODAC.etc)providesavingsanddirectmeasuresofeffectiveness. Cycletime improvementshavealsobeenimplemented(IPTs.OpenSystemArchitecture,3-DProductModels,etc). However, ship design managers have been unable to identify and quantify' design process effectiveness with respect to the impact of those proposed cycle time improvements. In order to understand the impact of cycle time improvements, it is necessary to examine the mechanisms which have lead to increased cycle time including external influences (such as increasmg technological complexity and budgetary pressures), internal process delays (information flow delays and approval delays) and feedback processes (design iteration, error propagation and design change.) Modeling of such mechanisms, using the methods of System Dynamics, provides a means to study past programs (in particular, the DDG-51 Destroyer program of the 1980s), and to study the anticipated savings that can be generated with the introduction of process improvements. Of particular interest in modeling the naval ship design process with System Dynamics is the flow of design information. Traditional process analysis methods based on the design spiral represent the progression of design tasksasalinearprocess. However,actualdesigndatapropagation(afundamentalpropertyresultingfromthe physical and architectural relationships of total ship systems) shows the process to be highly non-linear. These non- linearities are captured by system dynamics, providing a simulation tool that more fully captures the impacts of process improvements as they relate to the naval ship design process.

    Active Control of Adaptive Optics System in a Large Segmented Mirror Telescope 

    Nagashima, M.; Agrawal, B.N. (2012);
    For a large Adaptive Optics (AO) system such as a large Segmented Mirror Telescope (SMT), it is often difficult, although not impossible, to directly apply common Multi-Input Multi-Output (MIMO) controller design methods ...
