Enhancing data consistency in decision matrix: Adapting Hadamard model to mitigate judgment contradiction
We adapt Hadamard product operator to improve consistency ratio. The proposed model only requires the use of judgment in the original matrix. The cardinal and ordinal inconsistency can be processed by one model. Identify the ordinal inconsistency by graph theory. Independent of the scale employed in the positive and reciprocal matrix.
