摘要
针对TOPSIS法的不足之处,提出了一种改进方法:基于"垂面"距离的TOPSIS法——正交投影法.回顾了TOPSIS法.定义"垂面"距离,讨论垂面距离的计算、性质、以及与目标贴近度的关系.给出经过简化的正交投影法的计算步骤.举一个具体的例子,应用正交投影法进行评估.总结正交投影法的优点.
In allusion to the drawback of TOPSIS method,this paper puts forward a revised method:vertical projection method.First TOPSIS method is Reviewed.Then vertical projection distance is defined .Computation ,nature of vertical projection as well as relationship between vertical projection distance and the relative closeness to the ideal solutions is discussed.Afterwards simplified compute procedure of vertical projection method is presented.Vertical projection method is applyed to a real example.In the end, the merit of vertical projection method is summarized.
