Size of Pairwise Comparison Matrix
Fig.1:Size of Pairwise Comparison Matrix
- Input: Size of Pairwise Comparison Matrix, n (# of Evaluation Items or Alternative) where 2 ≤ n ≤ 9.
- If you will use non-integer values in Pairwise Comparison Matrix, please take off the check box "ONLY INTEGRER VALUES"
Input: Pairwise Comparison Matrix (Only Integer Values)
Fig. 2:Input: Pairwise Comparison Matrix
- Input the Pairwise Comparison Matrix
Input: Pairwise Comparison Matrix
Fig. 3:Input: Pairwise Comparison Matrix
- Input the Pairwise Comparison Matrix
- Do not use fractions
- You can use negative number -aij instead of fraction 1 / aij
- Example: 1/3 → -3, 1/2.8 → -2.8
Output
Fig.4: Output
- C.I. (Consistency Index): If the value is greater then 0.1 or 0.15, we recommend you to retry the Pairwise Comparison.
- Weight (Eigen Vector): Weights of Evaluation Items or Individual Scores of Alternatives
- Pairwise Comparison Matrix
