Combining the super-data envelopment analysis（DEA） model and the gray system theory, a new super-DEA for measuring the weight is proposed, and a gray relation projection model is established to rank the equipment programs. Finally, this approach is used to evaluate the equipment program. The results are verified valid and can provide a new way for evaluating the equipment program.展开更多
针对现有评价光伏并网影响指标不足或不尽合理的情况,提出了一套更为全面合理的两级化评价指标体系,对于一级和二级指标,分别采用主观赋权法和熵权法求取权重,从而得到二级指标的综合权重。采用综合权重和逼近理想解的排序方法(techniqu...针对现有评价光伏并网影响指标不足或不尽合理的情况,提出了一套更为全面合理的两级化评价指标体系,对于一级和二级指标,分别采用主观赋权法和熵权法求取权重,从而得到二级指标的综合权重。采用综合权重和逼近理想解的排序方法(technique for order preference by similarity to ideal solution,TOPSIS)对光伏并网的影响进行评价,不仅可以体现主观赋权的优越性,同时还能充分利用各种数据信息使评价结果更符合实际情况。实例表明,该方法是一种合理有效的评价方法。展开更多
