基于模糊可拓层次分析法的汽车绿色度评价体系研究

摘要

为了对汽车的绿色度进行量化评价,提出了基于整个生命周期的汽车绿色度评价指标体系,利用可拓层次分析法来为指标重要度赋权并获得排序,采用模糊综合评价获得汽车绿色度评价结果.解决了忽略主观判断模糊性的问题,实现了定性指标的量化评价,评价结果与实际相符.分析评价结果表明,燃油汽车的能源属性和环境属性绿色度较低,是影响汽车绿色度的关键因素.%In order to quantify the degree of the green car evaluation,a set of vehicle's green degree evaluation system is established in entire vehicle life cycle.The fuzzy-EAHP is an effective solution to vehicle's green degree evaluation system.Sort importance indicators are obtained by Extension AHP and vehicle green degree evaluation results are obtained by fuzzy comprehensive evaluation.Using fuzzy-EAHP,it solves the ignorance of fuzzy subjective judgments of the judgment matrix in the process of model construction,and shows an sample with vehicle to evaluate its green degree,The result is consistent with the reality.Through analysis of the result,it defines the main factor for vehicle's green degree.This system has a practical significance to improve the automobile manufacturing industry green degree and to increase the level of green design and green evaluation.
