A new version of of the AHP Excel template with some major updates is now available for download. Based on the work of Tomashevskii (2014, 2015), errors for the resulting priorities/weights are shown.
In addition the overall dissonance (ordinal inconsistency) according to Sajid Siraj (2011) is indicated. The zip file for download also contains the updated manual, showing the calculations and references.
In this latest version of the template, the balanced scale was replaced by the generalized balanced scale (balanced-n), and the adaptive scale was added. The maximum number of iterations for the power method was increased from 12 to 20.
If you need inputs for more than 20 participants, please contact the author. A version for up to 225 participants is available.
Most data generated with AHP-OS can be downloaded as csv files for import into a spreadsheet program and further analysis:
From the Hierarchy Input Menu – decision hierarchy and local & global priorities
From the Group Result Menu – Priorities by node and consolidated decision matrix
From the Project Data Menu – Decision matrices from each participant
For each download you can select “.” or “,” as decimal separator. The downloaded csv (text) file is coded in UTF-8 and supports multi-language characters like Chinese, Korean, Japanese and of course a variety of Western languages.
How to import into excel?
Open Excel, click on “File” -> “New” to have a blank worksheet. Click on “Data“. On the left top you will find the “Get External Data” box.
AHP-OS allows for downloading your project data as a comma separated value text file. The following menus include a csv download key:
Hierarchy Input Menu – download the AHP hierarchy
Group Result Menu – download resulting priorities and consolidated (aggregated) decision matrix
Project Data Menu – download decision matrices for all individual participants
Depending on your regional settings of your PC, for each download you can select the decimal point or decimal comma as decimal separator.
Text encoding of the CVS file is UTF-8. If you are using country specific characters and Windows Excel, you can convert from UTF-8 to ANSI. Open the CSV file with notepad, and save as a new file with Encoding set to ANSI.
Thanks to feedback from Benedikt, this latest update contains a minor change, to show the convergence of the power method, when calculating the eigenvalue. In the summary sheet a threshold (squared Euclidean distance d2) can be set, to show how many iterations it takes, until the change of the approximated eigenvector is below the given threshold. By default the value is set to Thresh: 1E-07:
In the above example it takes 7 iterations until d2 is below 1E-07. The actual difference is 3.5E-08 (EVM check). As the number of iterations in the template is fixed to 12, care should be taken if the value reaches 12.
In this latest update of my AHP excel template, input sheets were modified to show the proposed ideal judgments for the three most inconsistent inputs, resulting in a lower consistency ratio CR.
On the left side judgment A9, A7 and A6 are highlighted as inconsistent, CR is 32%. The consistent judgment is shown as A4, A9 and A3. After correction with the proposed intensities (right side) the consistency ratio decreases to 7% below the required threshold of 10%.
If you need a quick calculation of diversity indices from your sample data, you might use my online diversity calculator here. Select the number of categories/classes (2 to 20) and input your samples data (positive integer or decimal numbers). As a result the following parameters and diversity indices will be calculated:
Shannon Entropy (nat)
Shannon number equivalent (true diversity of order 1)
Simpson Dominance (finite sample size)
True diversity of order 2

Camera settings depend on the type of recorded video. The Canon XA-10 has only two full HD (1920×1080) recording modes: FXP and MXP. Based on these, most of my videos are recorded in FXP mode as it is a good trade-off between quality and file size.
Recording Modes of Canon XA-10
Edit and Archive
For video editing I use Adobe Premier Elements 10. Editing is done without changing codec (H264), resolution, interlacing, etc. As I have the PAL version of the XA-10, the Adobe project settings are AVCHD Full HD 1080i 25 under PAL. Once the video is edited, I render the clip with the highest quality settings (2 Pass VBR, Render at max. depth, Macro block Adaptive Frame-Field Coding), and a maximum bitrate corresponding to the source (FXP: 17 Mbps) for archiving. In Adobe Premier Elements 10 and for XA-10 FXP mode the settings are:
Archive settings in Adobe Premier Elements 10 for XA-10 FXP mode
Depending on the target media the clip to be published is adjusted in codec, resolution etc. I have predefined settings for:
Standard clips to be watched on a PC:
MP4 – PAL DV Widescreen SD – HiQ (576p, VBR 3/6 MBps)
MP4 – PAL DV Widescreen SD – LoQ(576p, VBR 1.3/2.6 Mbps)
Youtube as basic HD clip:
MP4 – HD 720p 25 (720p, VBR 2.5/5 Mbps)
In this latest update I followed the several requests to extend the number of participants (decision makers); you now can use the template for up to 20 participants. In addition the weight of individual participants can be adjusted for the aggregation of individual judgments (AIJ). For example, if you have one expert in the group, you might want to give him/her evaluation a x-time higher importance than the rest of participants. Then you simply change the weight in the input sheet from 1 to x. The calculation is done using the weighted geometric mean:
with cij = element of the consolidated decision matrix, aij(k) element of the decision matrix of participant k.
Kindly let me know in case you find any problem with this new version. Feedback is appreciated always! You can download this latestes version from my AHP template download page.
