The members of the committee responsible for the report were chosen for their special competencies and with regard for appropriate balance. The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encour- ages education and research, and recognizes the superior achievements of engineers. Dr. William A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. William A. Wulf are chairman and vice chairman, respectively, of the National Research Council. This study was supported by Contract No. NASW-4938 between the National Academy of Sciences and the National Aeronautics and Space Administration.

Generated for lgavrila@ub.ro on Tue Aug 26 05:14:37 2003 http://books.nap.edu/catalog/9597.html Economic pressures in the global economy are forcing aerospace and other high-technology industries to improve engineering performance in order to remain competitive. These improvements include faster insertion of new tech- nologies, lower design and development costs, and shorter development times for new products. One way to help real- ize improvements in project design and management on a global scale is through the development and application of advanced engineering environments (AEEs). AEEs would incorporate advanced computational, communications, and networking facilities and tools to create integrated virtual and distributed computer-based environments linking researchers, technologists, designers, manufacturers, suppli- ers, and customers. Significant progress has been made during the last 15 years in the application of computer-aided design, engineer- ing, and manufacturing systems. Building on that success, government, industry, and academia now have a historic opportunity to develop and deploy AEE technologies and systems. For example, the National Aeronautics and Space Administration (NASA) has initiated both near-term and far- term projects related to AEEs. As part of these efforts, NASA’s Chief Engineer and Chief Technologist requested that the National Research Council and the National Acad- emy of Engineering conduct a two-phase study to assess the current and future national context within which NASA’s plans must fit (see Appendix A). The Advanced Engineering Environments Committee was appointed to carry out this task (see Appendix B). The results of Phase 1, which focused on the near term (the next 5 years), are documented in this report. The results of Phase 2, which will focus on the far term (5 to 15 years), will be documented in the Phase 2 report. As described herein, the committee validated that AEEs could contribute to important objectives related to the devel- opment of complex new systems, products, and missions. However, advancing the state of the art enough to realize these objectives requires a long-term effort and must over- come a number of significant technical and cultural barriers. Much remains to be done in the near term, as well, both to v Preface lay the foundation for long-term success and to achieve near- term improvements in areas where technology has matured enough to improve the effectiveness of current practices. This report has been reviewed by individuals chosen for their diverse perspectives and technical expertise, in accor- dance with procedures approved by the National Research Council’s Report Review Committee. The purpose of this independent review is to provide candid and critical com- ments that will assist the authors and the National Research Council in making the published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge. The content of the review comments and draft manu- script remain confidential to protect the integrity of the deliberative process.
