AHP-OS New Release with simplified project administration

Based on feedback from users, I just released a major update of BPMSG’s AHP online software AHP-OS with simplified menu structure and additional functionality.  Starting the program as registered and logged-in user, the project session  table is displayed, showing your projects.

You can open one of your projects, either using a click on the session code in the project table, or selecting the session code from the session administration menu:

This will bring you to the project summary page, showing

AHP-OS News March 2017

I received some feedback about session timeout and expired session errors. I have now extended the session timeout to 45 min. After 45 minutes of inactivity (no refresh of html pages, click on menu botton, etc.) the session expires and session data are lost. Kindly feedback, if you still face a problem.

AHP-OS can handle multibyte characters (Chinese, Korean, Japanese etc.) Unfortunately, the bar chart of priorities on the group result page cannot handle these characters; the annotation of the axis will not be readable. I am working on a solution.

When doing a pairwise comparison – leaving all comparisons at the default value of 1 (equal importance) – criteria will get equal priorities. I implemented a confirmation message box: Are you sure to leave all comparisons at equal importance?  This was done in order to avoid unintential submission of the default values.

AHP-OS and Farsi

Thanks to the feedback of a user from Iran, I found out that AHP-OS is working with RTL fonts like Farsi. It is important to add the semicolon to the right end of a node definition, and use latin punctuation marks, for example:

کاربری: مسکونی , تجاری , اداری ;

A simple decision hierarchy example looks like here:

farsi

Unfortunately, I am not able to check for a hierarchy with more than one level. If anyone could provide a 2 level hierarchy, I would appreciate. Arabic fonts should work too; kindly contact me, if you have an example.

 

AHP Online Software CSV Data Export

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.

 

AHP Online Software – Decision Matrices – Update 2016-11-02

With the latest update of my AHP-OS online software you can now view and download the decision matrices of all participant. The group result menu was extended by a selection View Input Data:

g-result-menu

From there you reach the Project Detailed Input page, which shows the decision matrix for each individual participant and all nodes of the hierarchy:

projectinputdata

The project data menu has the button to download the data in csv format:

p-data-menu

The csv file contains the basic project data – Session Code, Project Name, Project description, Author, Date, Type of evaluation, Number of Participants – as well as all input decision matrices sorted by participant and nodes (categories of the hierarchy) or criteria for alternative evaluation.

With the Back link you can go back to the Group Result Page.

AHP Online Software – Latest Update 2016-10-29

Based on the request from some users I have modified the result display of my AHP-OS online software. Beside the resulting priorities it is now possible to see the underlying consolidated decision matrix, which results from the aggregation of individual judgments (AIJ) using the geometric mean.

Decision Hierarchies

For decision hierarchies the result page shows the resulting local and global priorities (overall result) in hierarchical form, and the global priorities in descending order in a bar graph.

Then, in a breakdown by nodes, consolidated priorities, consolidated decision matrix and the priorities of individual participants are shown:

ahp-result
As in this example, the consolidated matrix for one participant is the same as the AHP decision matrix.

Alternative Evaluation

For alternative evaluation the breakdown is done by criteria. It shows the consolidated preferences for all alternatives with respect to each of the criteria:

ahp-result1

In this example the House A from the alternative houses A, B, C has the best match with respect to the criterion “Size”.

Outlook

I am now working on the extension to let you download the complete set of input values, i.e. all underlying decision matrices, to excel. In the current version only the resulting AHP priorities are available.

Dear Friends, dear Visitors,

The analytic hierarchy process AHP remains the main topic of this website and continues to have the most visitors. As I continously receive quite a number of questions related to AHP, my AHP excel template and my AHP online software, I have summarized frequently asked questions (FAQs) in one posting here.

In between my online software was used by more than 3000 users, and has currently 500 active users. Please be reminded that after a period of 3 months inactive users will receive an re-activation email and be deleted, if they don’t reactivate their account.

After 3 months of inactivity, your user account will be deactivated automatically. Please reactivate, using the link provided in the e-mail, if you want to keep your data, otherwise your account and all your data will be deleted 48 hours after deactivation.

This is done to ensure a slim database and help to keep the software fast and responsive. Please also avoid multiple registrations under different user names and e-mail addresses. You can keep up to 20 projects in your account, and it should be sufficient for the majority of users.

AHP online program limits:

  • Number of hierarchy levels: 6 max.
  • Number of hierarchy nodes: 50 max.
  • Number of criteria/node: 15 max. ( 7 to 9 recommended)
  • Number of hierarchy end nodes: 150 max.
  • Number of Alternatives: 10 max.
  • String length for nodes/leafs: 35 char max.
  • Number of characters for hierarchy definition: 6000

Thank you for your cooperation, and PLEASE – as a registered user – help to support this website with a small donation. I do not have a commercial interest, but I spend a lot of time, sharing my knowledge for free, and I have running costs to keep the site alive.

Concepts, Methods and Tools to manage Business Performance

Dear Friends, dear Visitors,

The analytic hierarchy process AHP remains the main topic of this website and continues to have the most visitors. From October 2015 to now I received quite a number of questions related to my AHP excel template and my AHP online software. Here some of the typical questions (FAQs):

Q: Can I extend the number of participants to more than 20?
A: Though it is possible in principle, the better way is to use my AHP online software with (practically) unlimited number of participants. I will not do a further extension of the template.

Q: Do you have a version of the Excel template w/o multiple inputs?
A: Yes, a simplified version is available on request from the author.

Q: How can I cite your work, can you give me a reference?
A: Please cite my paper: Implementing the analytic hierarchy process as a standard method for multi-criteria decision making in corporate enterprises–a new AHP excel template with multiple inputs

Q: Do you support Fuzzy AHP?
A: No, I have made no provisions to support Fuzzy AHP, neither in Excel, nor in my online software.

Q: Can I use the Likert scale instead of the AHP scale?
A: No, AHP is based on the rational scale 1/9 … 1 … 9. It cannot be replaced by the Likert scale.

Q: How is the computation done, where do I find the description and formulas?
A: Please download my paper.

Q: How can I do alternative evaluation using your Excel template.
A: It is not possible. The template can only handle one category of a hierarchy and calculate the priority of one set of criteria.

Q: If I have a group of decision makers, do they need to register for the online software?
A: No, they don’t need to register. As the owner of a project you get a link for group decision inputs. Simply send them the link, and they can start the pairwise comparisons.
