AHP-OS – Editing saved projects

In the project menu of the latest AHP-OS version (2017-05-25), I added a button to edit saved projects. As long as there are no participants’ inputs (completed pairwise comparisons), any saved project’s hierarchy, alternatives or description can be modified.

Open a project from your project list, and click on Edit Project. The project hierarchy page will open with a message on top , indicating that you are modifying an existong project. You can now change the hierarchy, for example add criteria or alternatives. A click on Save/Update in the Hierarchy Input Menu

will overwrite the data of the original project under the same session code. You will see it in a message . Before you click on Go to save,  you  can also update the project short description:

Difference between Use Hierarchy and Edit Project

With Use Hierarchy in the project administration menu, the hierarchy window will open, and you can also modify the hierarchy or alternatives. But in contrast to Edit the modified project will be saved as a new project under a new project session code.

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:


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.
