基于在线供应链调查的产品生命周期评价

Product life cycle assessment based on online survey along supply chain

产品生命周期评价(LCA)中的供应链数据收集非常困难而且效率低下,因而在产品LCA研究中常常近似处理、甚至忽略供应链实际生产过程,严重影响了LCA的数据质量与可信度。开发专门的供应链数据收集工具是解决这一问题的有效途径。介绍了可进行在线供应链调查、建模与计算分析的LCA系统e Footprint,基于该系统提出了在线的LCA工作方法,通过长虹美菱冰箱的应用案例验证了系统与方法的可行性,为提高产品LCA的效率和质量提供了新的解决方案。

In product life cycle assessment（ LCA）,investigation of supply chain is so difficult and time-consuming that it is often overlooked,which significantly compromises LCA quality and credibility. Specialized tools for supply chain investigation are expected to solve this problem. An online LCA system,namely e Footprint,was introduced in this paper; this system was developed to conduct full LCA study online,including supply chain investigation,life cycle modeling,and analysis. Based on e Footprint＇s features,the guidelines for conducting LCA online were proposed. A pilot study of a refrigerator showed that e Footprint is a promising solution for more efficient and higher quality LCA work.
