基于模糊多属性决策的电能替代评价方法

Energy alternative evaluation method based on fuzzy multi-attribute decision making

以技术经济综合指标最优目标制定适合的电能替代方案,对于实现节能减排和能源综合利用具有重要意义。在电能替代方案中权重信息完全未知或仅知部分权重信息的情形下,提出基于期望值的模糊多属性决策方法;并构建优选评判指标体系,对指标属性值进行量化分析,采用互补两两比较赋权法,确定指标体系各层权值,实现电能替代方案的量化比较与优选。基于实例分析,验证了基于模糊多属性决策的电能替代评价方法能够充分利用客观已知的模糊信息,兼顾各方利益,具有高效、实用、易操作的特点。

The suitable energy alternatives scheme,which formulated based on the optimal target of technical and economic comprehensive indicators,is significant to achieve energy saving,emission reduction and comprehensive energy utilization.In the energy alternatives scheme,the fuzzy multi?attribute decisionmaking method based on the expectation value is proposed in the situation that the weight information is completely unknown or only partially known;and a preferred evaluation index system is constructed,to quantitative analysis the attribute values of the evaluation index.The weighting method of complementary comparison between each other is used to determine the weight of each layer in the index system,so as to realize the quantitative comparison and the optimized selection of energy alternative schemes.Based on the case study,it is verified that the energy alternative evaluation method based on fuzzy multiattribute decisionmaking is highly efficient,practical and easy to operate,at the same time,it can make full use of the fuzzy information which is objectively known and take into account the interests of all parties.
