CAREER: Integrated Product and De- and Remanufacture Process Design

9624787 BRAS美国国家科学基金会职业生涯奖为研究如何加强产品的集成设计以及拆解和再制造过程提供支持。需求制造被定义为在产品被一个或多个公司收回后，涉及回收、再利用、焚烧和/或处置产品的与制造相反的整个过程。这项工作的具体目标是：(1)建立一套扩展的商业和原型塑料-金属化学和机械产品去制造和再制造过程的操作参数和模型，(2)基于计算机的工具，用于塑料-金属产品的综合产品和工艺设计，以及相关的高性能和强大的去制造和再制造过程，以及(3)将这些新技术有效和有效地整合到工程教育中。这些目标将通过(1)分类适当的去制造和再制造工艺的技术、经济和生态性能，(2)开发去和再制造性能和稳健性评估的模型，(3)开发去和再制造过程选择和综合的工具，(4)将这种过程选择和综合与产品设计和综合模型相结合，以及(5)加强对新技术的教育和学习，特别是通过开发和评估新的课件和教育设施来加强对新技术的教育和学习。教育重点是：(A)通过创建一个学生可以对真实系统进行需求制造的设施，在实践中增加学习；(B)通过为拆卸和再制造制作关于产品和工艺设计的自学(多媒体)课件，增加对执业工程师(和其他人)的接触；以及(C)通过创建关于环境意识设计的国际课程，增加学生的多样性，鼓励整体思维。一个主要的问题是评估学生学习的有效性。第二个问题是教材交付的效率。该奖项将推动汽车等耐用品回收领域的进步。它将有助于提高美国在设计符合欧洲现行和即将出台的产品回收立法的产品和具有成本效益的回收工艺方面的竞争力。这项研究将有助于开发可回收、可重复使用的新技术，以及其他对环境无害的产品处置手段。其他切实的成果将是基于计算机的工具，这些工具将提供决策支持，并使设计师能够结合产品设计探索不同的回收过程场景。

9624787 Bras This NSF Career Award provides support for research on how to enhance the integrated design of products and de- and remanufacture processes. Demanufacture is defined as the entire process opposite to manufacture involved in recycling, reuse, incineration and/or disposal of products after they have been taken back by one or more companies. The specific objectives of the work are to establish (1) the operational parameters and models for an extended set of commercial and prototypical plastic-metal chemical and mechanical product de- and remanufacturing processes, (2) computer-based tools for integrated product and process design of plastic-metal products with associated appropriate high performance and robust de- and remanufacture processes, and (3) the efficient and effective integration of such new technologies in engineering education. These objectives will be achieved by (1) classifying the technical, economical and ecological performance of appropriate de- and remanfacture processes, (2) developing models for de- and remanufacturability performance and robustness assessments, (3) developing tools for de- and remanufacturability process selection and synthesis, (4) integrating this process selection and synthesis with product design and synthesis models, and (5) enhancing the education and learning about new technologies in general and de- and remanufacture in particular through the development and assessment of new courseware and educational facilities. Educational focal points are to (a) increase learning through doing by creating a facility where students can demanufacture real systems, (b) increase the outreach to practicing engineers (and others) by creating self-study (multi-media) courseware on product and process design for de- and remanufacture, and (c) increase the diversity of students and encourage holistic thinking by creating an international course on Environmentally Conscious Design. A primary issue is assessing the effectiveness of the learning that takes place by the students. A secondary issue is the efficiency of the delivery of the educational material. This award will provide advances in the field of recycling durable goods, like automobiles. It will help to increase the US competitiveness with respect to designing products and cost-effective recycling processes that will meet current and pending product take-back legislation in Europe. The research will contribute to new technologies for pursing recyclability, reusability, and other means of environmentally benign product disposal. Other tangible outcomes will be computer-based tools that will provide decision support and enable designers to explore different recycling process scenarios in conjunction with the product design.
