基于排序的AHP权重确定方法

Method for Deriving AHP Weight Based on Sorting

为了解决AHP应用过程中各元素权重的确定问题,建立一种新的比较尺度,提出一种基于排序的元素权重确定方法。在探讨新比较尺度的基础上,给出了元素权重确定过程的具体步骤、排序过程及元素权重计算公式。结果表明:该方法能解决元素权重确定过程中判断矩阵不一致问题,降低决策过程的复杂度,节约决策时间。

In order to solving the problem of deriving element weights of AHP, this paper constructs a new contrast measurement and presents a new deriving method based on sorting. Based on studying the new contrast measurement, the paper gives the detail steps and sorting process of deriving the element weights, and puts forward the formula of computing element weights. The result shows that the method solves judging matrix inconsistence problem, and reduces the degree of complexity of decision making process, and saves the time of decision making.
