How to extend the AHP Excel Template for more Participants?

As I received many requests to extend the number of participants in my AHP excel template, here a short information how to use it for more than 20 participants. There are two possibilities

  • Use my AHP online Software.
  • Use several templates, each  of them for up to 20 participants, and then combine the consolidated results in an additional summary template.
  • Modify the template.

As the template is quite complex, I strongly recommend to use the first possibility. But if you really want to modify the template itself, follow the step-by-step instruction below. This instruction does not include the AHP consensus indicator calculation.

  1. Unprotect sheet In20; create a copy of the sheet In20 and rename to In21.
  2. Go to “Formulas – Name Manager” and delete name Matrix20 with scope In21.
    Mark matrix cells of the decision matrix in In21 (C79:L88), and define new name Matrix21 with scope workbook.
    Go to Sheet multInp, unprotect sheet. Add additional matrix, e.g. copy/paste from matrix 20 (2 matrices per rows, same structure as for matrix 1-10).
    Mark content cells of new matrix and define new name “m_p21
    Set it {=Matrix21} ( {} = array function, see below).
    Mark the consolidated matrix (B9:K18), and modify the formula
    {=(M9:V18*B22:K31* …*B74:K83)^(1/N4)} to include the added participant’s matrix.
  3. Go to sheet Summary, unprotect sheet.
    Mark matrix starting at line 38, and add new matrix m_p11 in the formula: {=IF(p_sel>0;CHOOSE(p_sel; m_p1; m_p2; … ; m_p20; m_p21);MatrixC)}.
    Select field C7 (number of participants). Menu “Data – Data Validation”:
    change range from 1 to 20 to 1 to 21.
  4. Continue in the same way for additional participants.

Note:  {} is the Excel array function: mark cell area, and use Ctrl-Shift-Enter.

All matrices in the input sheets are named Matrixn, n = 1 to max. number of participants. (Matrix1, Matrix2, etc.)
The matrices in the multInp sheet are named “m_pn” (m_p1, m_p2, etc.)
