ABSTRACTThis paper suggests that many system development problems are due to the inadequacies of the mandated notations being used to support systems analysis and design An executable “behavior diagram” notation is proposed for describing system functionality which eliminates the deficiencies of the existing system analysis notations, yet can be displayed in those notations to strengthen the Systems Engineering process. The way in which this notation supports a separation of concerns for attacking large problems is also described. Finally, the role of automation is discussed to achieve increased system development productivity and reliabil

摘要:

AbstractBecause of the urgent schedule imposed on environmental issues, the Pond Waste Management Project (PWMP) implemented a tailored systems engineering (SE) approach for managing, integrating, and documenting its activities and for ensuring that both state and federal requirements for treating and storing low‐level radioactive mixed‐waste sludge would be met. This tailored approach focused on seven essential activities: system requirements, project plan, SE plan, configuration management plan, risk assessment, best management practices plan, and operational readiness rev

摘要:

AbstractThe fundamental concepts and process of systems engineering as they apply in the context of the National Aeronautics and Space Administration are described. In particular: Systems and systems engineering are defined, and the objectives of systems engineering are discussed. The doctrine of successive refinement is presented, and the associated spiral model of the systems engineering process is described. The various phases of the project cycle for major systems acquired by NASA are examined.This paper is based on material being prepared for the first draft of theNASA Systems Engineering Handbook. Consequently, the authors are seeking constructive criticism.

摘要:

AbstractThe Department of Defense acquisition process has gone through a decade of change intended to improve war fighting capabilities, to field products with a shorter cycle time, and to lower system life cycle costs. The intensity of change has increased during 1991 in response to the short comings of prior changes to correct acquisition problems and to deal with declining budgets, changing threats, and reduced manpower. The focus of this paper is on the major changes taken to re‐energize systems engineering. In addition, issues are highlighted that have resulted from several technical documents under revision at the same time without a formal integration or lead effort. This paper calls for someone in authority to take the lead to ensure that conflicting signals are not given to industry by the several different standards under revision. Harmonization is imperative if the rising expectations of defense and public leaders are to be realized in an environment of shrinking manpower and fiscal resource

摘要:

ABSTRACTIncreased competitive forces in domestic and foreign markets continue to cause government and industry to pursue strategies to achieve a competitive edge in the global marketplace. The premise of this paper is that an essential element for achieving a competitive edge is the practice of “World Class Systems Engineering” (WCSE).This author's view is that WCSE is a prerequisite to delivering total quality products and services. Less than WCSE can be expected to manifest itself in diminished “bottom‐line” results.This paper: (1) offers some observations on the current state of Systems Engineering; (2) provides a description of five essential elements of WCSE; and (3) asserts nine actions to achieve WCSE.To achieve WCSE, requires total quality management, or in the words of Dr. Malcolm Currie, Chairman and CEO, Hughes Aircraft Company “cmi” (Continuous Measurable

摘要:

ABSTRACTAcademic institutions, industry, and other components of our society are continuing a long standing trend toward fragmenting and specializing the arts and sciences related to the development of complex systems. The absence of an effective countervailing force encouraging generalism poses serious problems for American industry. Several examples exist illustrating how this trend can be turned around.

摘要:

ABSTRACTThe importance of Systems Engineering in the Aerospace Industry makes training in this field vital. Since such training is limited at Colleges, the industry must do it. The Lockheed two year training program includes courses to broaden the technical knowledge base, Systems Engineering Process training&on‐the‐job training assignments. The program includes careful student selection, the use of mentors, key subject seminars, and special student group eve

摘要:

AbstractNASA has instituted a Systems Engineering Training Program as part of its Program and Project Management Training Initiative (PPMI). The PPMI has several elements, including Project Management, Program Control, Human Development and Systems Engineering. PPMI also includes special training such as Source Evaluation Boards, SRM&QA, TQM, and Program/Project Management shared experience workshops. The Systems Engineering Training Program develops and delivers systems engineering courses NASA‐wide. In addition, the program includes an intercenter working group which holds monthly videocons to exchange information on system engineering techniques and practices NASA‐wide. A NASA Systems Engineering Handbook is being developed which will:Represent a basic NASA‐tailored systems engineering process.Provide reference pointers to material on systems engineering techniques, technologies and practices.Provide documentation of material which will be used in the courses offered by

AbstractA new way of portraying the technical aspect of the project cycle clarifies the role and responsibility of system engineering to a project. This new three dimensional graphic illustrates the end‐to‐end involvement of system engineering in the project cycle, clarifies the relationship of system engineering and design engineering, and encourages the implementation of concurrent engineer
