“…In general, multi-criteria LCA evaluations that include environmental performance can be decomposed as depicted in Figure 1. Similar decompositions have been proposed (for example [14,15]), though none are identical in form or scope to the structure presented here. Components are grouped, as indicated by dashed-lines in the figure, using Hofstetter's concept of "spheres" of knowledge and reasoning about environmental evaluation [14]:…”

Information-Gap Decision Theory (IGDT), an approach to robust decision making under severe uncertainty, is considered in the context of a simple life cycle engineering example. IGDT offers a path to a decision in the class of problems where only a nominal estimate is available for some uncertain life cycle variable that affects performance, and where there is some unknown amount of discrepancy between that estimate and the variable's actual value. Instead of seeking maximized performance, the decision rule inherent to IGDT prefers designs with maximum immunity (info-gap robustness) to the size that the unknown discrepancy could take. This robustness aspiration is subject to a constraint of achieving better than some minimal requirement for performance. In this paper, an automotive oil filter selection design example, which involves several types of severe uncertainty, is formulated and solved using an IDGT approach. Particular attention is paid to the complexities of assessing preference for robustness to multiple severe uncertainties simultaneously. The strengths and limitations of the approach are discussed mainly in the context of environmentally benign design and manufacture.

The challenge of realigning the present path of development on a sustainable trajectory concerns all sectors of society, including engineering. To move towards a sustainable practice of engineering, the design process needs to be modified in order for engineers to efficiently tackle the related issues. Such 'sustainable design processes' (SDPs) are proposed in the literature. By reviewing the conventional design process and SDP, this paper aims to identify the differences between both approaches. The potential contribution of recent design theories, methods and techniques to sustainable engineering is also briefly discussed. Tasks from existing SDPs are combined with crucial complements into a novel integrated sustainable engineering design process. Instead of representing conventional and sustainable engineering as a dichotomy, this paper places both paradigms on a continuum along which the engineer can position himself and assess his progress. The proposed procedure reveals shades of sustainability along six dimensions: (1) the structure of the design process, (2) the scope of sustainability issues covered, (3) the relevance of the indicators considered, (4) the accuracy of the tools used for evaluation, (5) the potential improvements expected from the alternatives assessed and (6) decision-making.

“…Reduction of EIs must be considered, wherever possible, in the processes involved and in the logistic operations. Lu and Gu [2003] have presented an analysis of a product's life cycle processes. The model, in addition to the production supply chain, includes recycling, repair, reuse, and so on.…”
