Effective design and manufacturing, both of which are necessary to produce high-quality products, are closely related. However, effective design is a prerequisite for effective manufacturing. This new book explores the status of engineering design practice, education, and research in the United States and recommends ways to improve design to increase U.S. industry's competitiveness in world markets.
As the Department of Defense continues development of the future warrior system, the difficulty of moving rapidly from design to manufacturing for complex technologies is becoming a major concern. In particular, there are communication gaps between design and manufacturing that hinder rapid development of new products important for these future military developments. To help address those concerns, DOD asked the NRC to develop a framework for "bridging" these gaps through data management, modeling, and simulation. This report presents the results of this study. It provides a framework for virtual design and manufacturing and an assessment of the necessary tools; an analysis of the economic dimensions; an examination of barriers to virtual design and manufacturing in the DOD acquisition process; and a series of recommendations and research needs.

Intelligent manufacturing control for improved reliability and greater precision. Building a workforce with the multidisciplinary skills needed for competitiveness. This sound and accessible analysis will be useful to manufacturing engineers and researchers, business executives, and economic and policy analysts.
Conventional wisdom holds that high wages, high capital costs, and worker inflexibility have cost America its ability to compete in the world manufacturing marketplace. This book demonstrates that U.S.-based manufacturing can compete in terms of quality, product features, and timely deliveryâ€"the real measures of competitiveness in the 1990s. The committee identifies attributes that attract manufacturers to given locations and assesses the attractiveness of the United States as a location for different kinds of manufacturing. The volume dispels myths that have guided management decision making in the past and offers recommendations to promote the United States as a manufacturing site. The volume discusses new approaches to understanding and controlling costs. With case studies from three important industriesâ€"consumer electronics, semiconductors, and automobilesâ€"the book explores factors in site location decisions, highlighting advantages the United States can offer as a manufacturing site over low-cost rivals.
Product liability is a contentious issue. Proponents argue that American tort law promotes product safety. Manufacturers contend that lawsuits chill new product development. Product Liability and Innovation provides an overview and an engineering perspective on the product liability system. The volume offers studies of selected industries, exploring the effect of product liability on corporate product development decisions and on the creative opportunities and day-to-day work of engineers. The volume addresses the potential liability of the parts or materials supplier and discusses the impact of liability on the availability of insurance. It looks at "junk science" in the courtroom and analyzes opportunities to incorporate into product design what we know about human behavior and risk. The book also looks at current efforts at tort reform and compares U.S. injury claims handling with that of other countries. This volume will be important to policymakers, industrialists, attorneys, product engineers, and individuals concerned about the impact of product liability on the industrial future.
Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
Through innovative design, creation, processing, use, and disposal of substances, the chemical industry plays a major role in advancing applications to support sustainability in a way that will allow humanity to meet current environmental, economic, and societal needs without compromising the progress and success of future generations. Based on a workshop held in February 2005 that brought together a broad cross section of disciplines and organizations in the chemical industry, this report identifies a set of overarching Grand Challenges for Sustainability research in chemistry and chemical engineering to assist the chemical industry in defining a sustainability agenda. These Grand Challenges include life cycle analysis, renewable chemical feedstocks, and education, among others.
The report assesses the current state of chemistry and chemical engineering at the interface with environmental science, examines its interactions with related areas of science and technology, and identifies challenges and opportunities for research. The report also identifies important contributions that have been made by the chemical sciences toward solving environmental problems, and emphasizes the opportunities for chemists and chemical engineers to make future contributions toward understanding and improving the environment.
This is the first report of seven in the Challenges for the Chemical Sciences in the 21st Century series. The report is based on discussions and presentations at a workshop, and is intended to help scientists and funding agencies set short- and long-term research agendas. It focuses on the challenges for chemists and chemical engineers with respect to threat reduction, preparation, situational awareness, and threat neutralization and remediation
The goal of this study was to assess the value and feasibility of developing and implementing content standards for engineering education at the K-12 level. Content standards have been developed for three disciplines in STEM education-science, technology, and mathematic-but not for engineering. To date, a small but growing number of K-12 students are being exposed to engineering-related materials, and limited but intriguing evidence suggests that engineering education can stimulate interest and improve learning in mathematics and science as well as improve understanding of engineering and technology. Given this background, a reasonable question is whether standards would improve the quality and increase the amount of teaching and learning of engineering in K-12 education. The book concludes that, although it is theoretically possible to develop standards for K-12 engineering education, it would be extremely difficult to ensure their usefulness and effective implementation. This conclusion is supported by the following findings: (1) there is relatively limited experience with K-12 engineering education in U.S. elementary and secondary schools, (2) there is not at present a critical mass of teachers qualified to deliver engineering instruction, (3) evidence regarding the impact of standards-based educational reforms on student learning in other subjects, such as mathematics and science, is inconclusive, and (4) there are significant barriers to introducing stand-alone standards for an entirely new content area in a curriculum already burdened with learning goals in more established domains of study.
Effective design and manufacturing, both of which are necessary to produce high-quality products, are closely related. However, effective design is a prerequisite for effective manufacturing. This new book explores the status of engineering design practice, education, and research in the United States and recommends ways to improve design to increase U.S. industry's competitiveness in world markets.
Engineering education is emerging as an important component of US K-12 education. Across the country, students in classrooms and after- and out-of-school programs are participating in hands-on, problem-focused learning activities using the engineering design process. These experiences can be engaging; support learning in other areas, such as science and mathematics; and provide a window into the important role of engineering in society. As the landscape of K-12 engineering education continues to grow and evolve, educators, administrators, and policy makers should consider the capacity of the US education system to meet current and anticipated needs for K-12 teachers of engineering. Building Capacity for Teaching Engineering in K-12 Education reviews existing curricula and programs as well as related research to understand current and anticipated future needs for engineering-literate K-12 educators in the United States and determine how these needs might be addressed. Key topics in this report include the preparation of K-12 engineering educators, professional pathways for K-12 engineering educators, and the role of higher education in preparing engineering educators. This report proposes steps that stakeholders - including professional development providers, postsecondary preservice education programs, postsecondary engineering and engineering technology programs, formal and informal educator credentialing organizations, and the education and learning sciences research communities - might take to increase the number, skill level, and confidence of K-12 teachers of engineering in the United States.
Advances in the capabilities of technologies applicable to distributed networking, telecommunications, multi-user computer applications, and interactive virtual reality are creating opportunities for users in the same or separate locations to engage in interdependent, cooperative activities using a common computer-based environment. These capabilities have given rise to relatively new interdisciplinary efforts to unite the interests of mission-oriented communities with those of the computer and social science communities to create integrated, tool-oriented computation and communication systems. These systems can enable teams in widespread locations to collaborate using the newest instruments and computing resources. The benefits are many. For example, a new paradigm for intimate collaboration between scientists and engineers is emerging. This collaboration has the potential to accelerate the development and dissemination of knowledge and optimize the use of instruments and facilities, while minimizing the time between the discovery and application of new technologies. Advanced Engineering Environments: Achieving the Vision, Phase 1 describes the benefits and feasibility of ongoing efforts to develop and apply advanced engineering environments (AEEs), which are defined as particular implementations of computational and communications systems that create integrated virtual and/or distributed environments linking researchers, technologists, designers, manufacturers, suppliers, and customers.
Computational methods are rapidly becoming major tools of theoretical, pharmaceutical, materials, and biological chemists. Accordingly, the mathematical models and numerical analysis that underlie these methods have an increasingly important and direct role to play in the progress of many areas of chemistry. This book explores the research interface between computational chemistry and the mathematical sciences. In language that is aimed at non-specialists, it documents some prominent examples of past successful cross-fertilizations between the fields and explores the mathematical research opportunities in a broad cross-section of chemical research frontiers. It also discusses cultural differences between the two fields and makes recommendations for overcoming those differences and generally promoting this interdisciplinary work.
Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
The Committee on Modeling and Simulation Enhancements for 21st Century Manufacturing and Acquisition was formed by the NRC in response to a request from the Defense Modeling and Simulation Office (DMSO) of DOD. The committee was asked to (1) investigate next-generation evolutionary and revolutionary M&S capabilities that will support enhanced defense systems acquisition; (2) identify specific emerging design, testing, and manufacturing process technologies that can be enabled by advanced M&S capabilities; (3) relate these emerging technologies to long-term DOD requirements; (4) assess ongoing efforts to develop advanced M&S capabilities and identify gaps that must be filled to make the emerging technologies a reality; (5) identify lessons learned from industry; and (6) recommend specific government actions to expedite development and to enable maximum DOD and U.S. commercial benefit from these capabilities. To complete its task, the committee identified relevant trends and their impact on defense acquisition needs; current use and support for use of M&S within DOD; lessons learned from commercial manufacturing; three cross-cutting and especially challenging uses of M&S technologies; and the areas in which basic research is needed in M&S in order to achieve the desired goals for manufacturing and defense acquisition.
