Method for measuring the satisfactory consistency of a linguistic j udgement matrix
Cuiping Wei · Systems Engineering - Theory & Practice · 2009
We first analyze the rationality of the existing definitions on the satisfactory consistency of a linguistic judgement matrix,give a notion of the satisfactory consistency index and present a method to compute the index.Using the method,we can measure the satisfactory consistency of the linguistic judgement matrix,find out all the teams of the judgment elements that are illegitimate in the linguistic judgement matrix,and then,we solve the problem that there is no judgement method for the satisfactory consistency of a linguistic judgement matrix with non-strict pairwise comparison information.Finally,we illustrate the validity and potential practicality of this method with two examples.
