层次分析法在生命周期评价中的改进应用研究

Application of Improved Analytical Hierarchy Process in Life Cycle Assessment

层次分析法是一种实用的、多目标决策方法,生命周期评价被看作是21世纪最有潜力的环境管理工具。将层次分析法应用于生命周期评价能够实现生命周期过程多指标的综合评价,但在传统的层次分析法中,仅仅是对一级指标进行简单的叠加,但在实际的应用过程中,不同的指标对综合效益的贡献是不一样的,因此,论文对传统的层次分析法进行了改进,并对某矸石电厂进行评价,充分考虑指标对综合效益的影响,对各指标作赋值处理,使得评价结果更准确。

Analytic hierarchy process （AHP） is an applied method which can be used for multi-object decision making while the life cycle assessment （LCA） is seen as the most potential environment management tool. The application of an addition in the conventional AHP to the LCA can integrated evaluate the indexes, however different indexes have different devotion effects on integrated benefit. Some improvements were made to the conventional AHP in terms of the effect of various indexes, which were used for an assessment of a coal power plant with more satisfactory results.
