Environmentally Conscious Design

With increasing environmental regulations and waste management costs, environmentally conscious design and manufacturing (ECDM) and surplus asset recovery are becoming a more attractive approach to solve environmental problems. Any company that owns a collection of PCs, printers and other electronic accessories probably needs to manage these assets more effectively, but currently there is a lack of tools for effective management. Therefore, this paper discusses, from the viewpoint of an enterprise dealing with end-of-life electronic products, the recycling processes according to literature, and derives an integrated model on surplus asset management and environmental impact analysis. The primary objective of the model is to develop a certain tool for managing surplus asset within a corporate office and generate a decision making tool for those who are concerned with the environmental issues in the design or recycling phase. Based on this model, a prototype system is introduced in detail in this paper.

Environmentally Conscious Design

Abstract This paper approaches environmentally conscious design by further developing a reliability model that facilitates design for reuse. Many reliability models are not suitable for describing systems that undergo repairs performed during remanufacture and maintenance because the models do not allow the possibility of system reconfiguration. In this paper, expressions of reliability indices of a model that allows system reconfiguration are developed to enable life-cycle cost estimation for repairable systems. These reliability indices of a population of repairable systems are proven theoretically to reach steady state. The expressions of these indices at steady state are obtained to gain insight into the model behavior, and to facilitate life-cycle cost estimation.
