Welcome to BPMSG – July 2020

Dear Friends, dear Visitors,

After a full year without any update to this entry page, it is time to say a few words about the current status.

Over the last years my free AHP online software AHP-OS gained popularity; as of now I have more than 12 thousand registrations and more than one thousand active users. It seems, the software – in its latest version from Sep 2019 – is quite stable. I only receive very few bug reports and a few suggestions for improvements. When you use the software, please make a reference to my paper published in IJAHP about AHP-OS from 2018.

Recently I received feedback on my Diversity calculator Excel template. It can be used to analyze consensus among decision makers using the AHP consensus indicator based on Shannon alpha and beta entropy.

There was a correction in the calculation of the consensus indicator, not yet implemented in the diversity calculator template. With the latest version this now has been updated too.

In the last couple of months I shifted my focus from (AHP) software development using PHP to other software development using Python, yet I will maintain AHP-OS in future. Please let me know if you find any bugs.

Many thanks to all donors, supporting this website, please continue to support my effort with a small donation, especially when you use my free templates or online software.

For now, please enjoy your visit on the site and feel free to leave a comment – it is always appreciated. And keep in mind: Better to be approximately right than precisely wrong.
