AHP group decision making

The figure below shows, how a group session is conducted to determine group priorities using BPMSG’s AHP online system. The group session chair initiates a group session (You need to be registered and logged in). A six character session code is generated. Participants can use this session code to log into the group session and provide their judgments. Try out a practical example, where you can participate and input your judgments

Example showing the result for two participants. See also my post about group decision making.

AHP Online Software – Version 2014-03-15

I just released a new version of my AHP Online Software. It includes the possibility to do group sessions: several participants can make the pairwise comparison, and you can view the consolidated group result.

After definition of the hierarchy using the AHP online system, click on “New Group Session” (You need to login  as  registered user). A session code will be provided. Enter your name, start the pairwise comparisons and submit for group evaluation.

Note down the session code, and provide the link, shown under the active group session, to your participants to log in and do their pairwise comparisons.

You can view the group result, once data are submitted, with a click on “View group results”. You might always review results by using the session code and your name using the AHP Group Session link.

Please be aware that this version is still a beta version. Kindly feedback any problems or bugs.
