Computing Weight Vector of Comparison Matrix in AHP based on Improved Least Square |
|
| Abstract: | A new approach based on least square method to calculate the weight vector of comparison matrix in the analytical hierarchy process(AHP) was proposed.Fixing one element of the weight vector as a constant and judging from the upper triangular part of the comparison matrix,this paper designed a new algorithm for calculating the weight vector of comparison matrix,which is simple,easy for computation and of the same derived scale of eigenvector ranking method.The existence and uniqueness of the solution is proved.The experiment indicates that it is valid and practicable. |
