Research Initiation: Enhancing Reusability by Design

[9410005]胸罩人们对环境，尤其是垃圾和垃圾填埋场的日益关注，促使人们研究设计更环保的产品。产品再利用可以大大减少对环境的影响，与材料回收相比，产品的几何形状得以保留，其相关的经济和环境价值得以保留。然而，当需要量化环境属性和要求时，试图产生正式和系统的设计方法，其中包括环境因素，如可重复使用以及经济、机械和其他设计因素，就会失败。在本研究中，目标是确定量化和增强设计中的可重用性的高效和有效的度量。为了实现这一目标，基于影响工程系统可重用性的生命周期因素，假设了可重用性度量。开发了一个验证策略来确定这些度量的正确性和有效性。其中，使用来自合作工业伙伴的历史设计和服务数据来验证假设的度量。不确定性和可变性也是考虑的关键方面。设计对环境无害的产品是一个对国家至关重要的领域。成功的研究成果可以被工业设计界用来改进产品开发活动。该项目具有较强的产业支撑。

9410005 Bras A growing concern about the environment, and especially about waste and landfill, has spurred research into the design of more environmentally benign products. A dramatic reduction in environmental impact can be made by product reuse in which, in contrast to material recycling, the geometrical form of the product is retained and its associated economical and environmental value is preserved. However, attempts to generate formal and systematic design approaches which include environmental considerations such as reusability as well as economical, mechanical and other design considerations break down when confronted with the need to quantify environmental properties and requirements. In this research the objective is to identify efficient and effective metrics for quantifying and enhancing reusability in design. In order to achieve this objective, reusability metrics are postulated based on life cycle factors affecting reusability of engineering systems. A validation strategy is developed to determine the correctness and validity of these metrics. Among others, the postulated metrics are verified using historical design and service data from cooperating industrial partners. Uncertainty and variability are key aspects which are taken into account as well. Design of environmentally benign products is an area of critical national importance. Successful research results could be used by the industrial design community to improve the product development activities. The project has strong industrial support.
