    Tradeoff studies are the core technology of the system engineer during the early design effort. The system engineer creates tools to analyze performance, reliability, human interfaces, and cost. The entire life of the system is fixed by the system engineers' imagination during the initial design. After drawings are released, the principal activities of the system engineer are the resolution of int... View full abstract»

    Proper implementation of system engineering (SE) concepts and principles requires a breakdown of the overall SE process into specific activities and tasks. For maximum effectiveness, appropriate SE practices and methods should be identified, selected, adapted, and then applied in an integrated manner. A systematic approach to identify relevant practices and methods, as a function of the phase of t... View full abstract»

    A process for developing originating requirements is described. Originating requirements are the cornerstone upon which the systems engineering process is based. These requirements do not just appear, but involve a great deal of work using several important systems engineering tools: the operational concept, the external systems diagram, and the objectives hierarchy. In addition, this work provide... View full abstract»

    Intelligent transport systems (ITS) are members of an emerging class of systems which have highly distributed architectures and are equally distributed in their development, procurement, and management. Important characteristics of such systems include: (1) the lack of a client with ownership and developmental responsibility for the system, (2) considerable uncertainty in system purposes and a rec...

  • Statistical interpretation of absolute system performance requirements

    Publication Year: 1997 , Page(s): 626 - 631
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1284 KB)  

    For critical functions within a system, many times a customer specifies stringent performance requirements parameters in absolute terms. Strictly interpreted, these requirements must be met 100% of the time. Ideally, the system has to be tested for all possible combinations of input parameters for such functions. This is cost-prohibitive, especially in the case of complex systems for which it is n... View full abstract»

    The world has changed dramatically in the past ten years due to many political, technical, and cultural imperatives. One of the key areas both affected by these changes as well as the center of the transformations is the ability to transport people and cargo quickly, efficiently, and safely anywhere in the world. Modern jet transports represent one of the largest and most complex design problems k... View full abstract»

    The 777 Airplane Information Management System (AIMS) has successfully completed its first year of airline revenue service. This in-service success follows a development and integration program that was an exceptional challenge, primarily due to the system size, technical innovation, and aggressive program schedule. Honeywell and Boeing had to work closely together to complete the design and devel... View full abstract»

    The 777 Airplane Information Management System (AIMS) was one of the largest avionics systems development programs ever undertaken by Boeing for a commercial airplane. The scope and complexity of AIMS provided many system engineering challenges in all program phases. Traditional strategies had to be reviewed and updated to meet new demands. The 777 Working Together initiative, which emphasized com... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2163 KB)  

    The value of systems engineering and a vision of automation to aid the search for near optimal system designs is described. Realizing that vision requires application of modeling to system development and the definition of systems engineering itself. The approach is a synthesis of systems engineering best practices with the rigor of software engineering. The basic abstractions and processes requir... View full abstract»

    During the last ten years scientists in diverse fields such as economics, biology, and systems science have been asking the question, "What is it that makes some systems complex?" The traditional reductionist/mechanistic paradigm has failed to answer this system complexity question satisfactorily. An expansionist/context-sensitive system (CSS) paradigm, that includes the traditional reductionist/m... View full abstract»

    The author discusses the value of the now-released Swerling (1996) paper (ibid., pp. 698-709) in which chi-square target models replace the now-obsolete Swerling models and the merits of the papers by Xu & Huang (ibid., pp. 710-14) and Johnston (ibid., pp. 715-20). View full abstract»

    The chi-square family of signal fluctuation distributions is defined. Rules are given for embedding the Swerling cases, and other cases of interest, in this family. Probability of detection curves are presented for the chi-square family of fluctuations, including cases whose probability of detection curves cannot be bracketed by the Swerling cases and the non-fluctuating case. The work of Weinstoc... View full abstract»

    In this paper, we point out the drawbacks of conventional target fluctuation models used in radar target modeling. It is usually difficult for us to statistically model a real target by a conventional target model which has an analytical probability density function (pdf) expression, because there are very few parameters which can be used to approximate in conventional target models the pdf of the...

    It is a very common custom to use extremely simple target models in specification for radar, radar system design, performance analysis, comparison, and evaluation. While the use of rudimentary models simplifies the work, their use can only result in ultimate disappointment of the radar user, severe illness in the course of the radar development and testing, followed by major surgery, and sometimes...

    Increasing scientific evidence strongly supports the conclusion that the major extinctions in the history of life on Earth were caused by the impact of large near-Earth-orbit objects (NEOs) and that these impacts will continue. Although the annual likelihood of this threat from asteroids and comets is extremely low, the consequences are so disastrous they have no precedent in human history. Altern... View full abstract»
