    Advanced Information Processing System (AIPS) is a computer systems philosophy, a set of validated hardware building blocks, and a set of validated services as embodied in system software. The goal of AIPS is to provide the knowledgebase which will allow achievement of validated fault-tolerant distributed computer system architectures, suitable for a broad range of applications, having failure probability requirements of 10E-9 at 10 hours. A background and description is given followed by program accomplishments, the current focus, applications, technology transfer, FY92 accomplishments, and funding

    DDG-1000 missile integration: a case study

    Get PDF
    This thesis is a case study that examines missile development and integration for the DDG-1000 program. In particular, it analyzes various programmatic decisions through the lens of systems engineering standards, articles in scholarly journals, established government acquisition guidelines, and case studies of government and commercial engineering projects. Four risks were identified. First, failure to establish top-level requirements that reflect DDG- 1000 specific needs introduces the potential for the missiles to fail performance or safety evaluations. Second, late requirement changes imposed by the government increase the potential for costly rework and schedule delays if integration issues surface during testing. Third, a use as is decision (meaning that legacy missile requirements were applied to the DDG-1000 missile effort) could result in an inadequate system architecture and/or late identification of system incompatibilities. Finally, organizational and funding issues have hampered the establishment and efficiency of engineering change control and integration management. The thesis recommends: that DOD acquisitions continue to emphasize and enable rigorous application of system engineering early in the acquisitions process; that all programs perform a thorough flow-down of requirements even if utilizing legacy systems; and that all funding for weapon development be placed in the control of the Program Executive Office for Integrated Warfare Systems.http://archive.org/details/ddgmissileintegr1094541425Lieutenant Commander, United States NavyApproved for public release; distribution is unlimited

    Advanced information processing system: The Army fault tolerant architecture conceptual study. Volume 2: Army fault tolerant architecture design and analysis

    Get PDF
    Described here is the Army Fault Tolerant Architecture (AFTA) hardware architecture and components and the operating system. The architectural and operational theory of the AFTA Fault Tolerant Data Bus is discussed. The test and maintenance strategy developed for use in fielded AFTA installations is presented. An approach to be used in reducing the probability of AFTA failure due to common mode faults is described. Analytical models for AFTA performance, reliability, availability, life cycle cost, weight, power, and volume are developed. An approach is presented for using VHSIC Hardware Description Language (VHDL) to describe and design AFTA's developmental hardware. A plan is described for verifying and validating key AFTA concepts during the Dem/Val phase. Analytical models and partial mission requirements are used to generate AFTA configurations for the TF/TA/NOE and Ground Vehicle missions

    A methodology for topside design and integration in preliminary warship design.

    Get PDF
    This thesis investigates warship topside design and integration and proposes a methodology that provides, during the preliminary design stages, an enhanced topside design capability above that currently available. The feasibility of such a system is demonstrated through a number of individual investigations and ship design studies for both conventional and unconventional naval vessels. A recommended implementation of the methodology, integrating it with the recently produced layout system, is proposed as the way forward. Topside design is a complex task resulting from the requirement to locate all the necessary equipment on the weatherdeck and superstructure of a warship whilst minimising interactions. The current tools and design methodologies fail to cohesively address design issues at the concept stage. This is often due to the specialist nature of the analyses, which require detailed definitions only available later in the design process as well as expert knowledge in the application of the techniques. The proposed methodology provides guidance as different design solutions are developed and evaluated, allowing earlier identification of potential problems. It operates in an 'open' manner providing the naval architect with the flexibility to investigate and analyse the design as it evolves without dictating design decisions or requiring expert application knowledge. The major issues that need to be considered during preliminary warship design are discussed. Current design methods and the shortfalls associated with each of them are considered. A methodology is outlined detailing the principles that are applicable and the important components and characteristics of any solution identified. The major aspects in topside integration are investigated and design tools proposed and evaluated. A framework for the integration of these tools is developed which is suitable for implementation using current computer technology. The suitability of this framework to incorporate other less complex but important topside design issues is evaluated and appropriate techniques identified

    Assessment of avionics technology in European aerospace organizations

    Get PDF
    This report provides a summary of the observations and recommendations made by a technical panel formed by the National Aeronautics and Space Administration (NASA). The panel, comprising prominent experts in the avionics field, was tasked to visit various organizations in Europe to assess the level of technology planned for use in manufactured civil avionics in the future. The primary purpose of the study was to assess avionics systems planned for implementation or already employed on civil aircraft and to evaluate future research, development, and engineering (RD&E) programs, address avionic systems and aircraft programs. The ultimate goal is to ensure that the technology addressed by NASa programs is commensurate with the needs of the aerospace industry at an international level. The panel focused on specific technologies, including guidance and control systems, advanced cockpit displays, sensors and data networks, and fly-by-wire/fly-by-light systems. However, discussions the panel had with the European organizations were not limited to these topics
