Environmentally Conscious Manufacturing: Design for Environment of Electromechanical Product Families and Generations

9528615石井这个项目开发了一种方法，通过关注模块化、材料/工艺选择和退役规范来评估机电产品的环境影响。该方法将解决整个产品线(系列)和产品随时间(世代)的变化。该项目的重点是确定评估可重用性/可回收性所需的数据和公式。相关因素包括：(1)嵌入式功能的技术生命周期；(2)作为服务部件的再利用需求；(3)回收材料的价值与再加工成本；(4)破坏性或非破坏性拆卸；以及(5)与制造和服务成本的权衡。行业合作者将在开发该方法时提供验证示例。如果成功，该项目将生产一个可访问互联网的工具，模拟产品退役过程，确定成本驱动因素，并改进生命周期设计。该工具将提高产品的可回收性和可重用性，同时降低生命周期成本和提高质量。这种方法应该减少固体废物，延长资源的使用寿命，不仅要解决单个产品的问题，而且要解决产品线上的家庭问题，并随着时间的推移延长资源的寿命。该项目将通过斯坦福大学教学电视网向20多家公司提供的可制造性设计研究生课程，为工程教育做出贡献。

9528615 Ishii This project develops a method to evaluate the environmental impact of electromechanical products by focusing on modularity, material/process selection, and retirement specification. The method will address the entire product line (families) and product changes over time (generations). The project focuses on identifying the data and formulae necessary to evaluate reusability/recyclability. The pertinent factors include: (1) technology life-cycle of embedded functions; (2) demand for reuse as service parts; (3) value of recycle materials versus the reprocessing cost; (4) destructive or non-destructive disassembly; and (5) trade-off with manufacturing and service costs. Industrial collaborators will provide validation examples in developing the method. If successful, the project will produce an Internet accessible tool that simulates the product retirement process, identifies cost-drivers, and improves the life-cycle design. The tool will enhance the recyclability and reusability of products, while reducing life-cycle costs and improving quality. The method should reduce solid waste and extend the life of resources by addressing not only individual products but their families across product line and generations over time. The project will contribute to engineering education through a graduate course on Design for Manufacturability delivered to over twenty companies through Stanford Instructional Television Network.
