Welcome to BPMSG – Jan 2021

Dear Friends, dear Visitors,

Thank you for visiting BMPSG; another six months passed and – probably due to Covid 19 – the interest in my online tools for business performance management and the Analytic Hierarchy Process is not declining.

My free AHP online software AHP-OS gained popularity. I haven’t made major modifications, but I am pleased to announce the addition of the Spanish language version. Just click on “Español” on the entry page, and all text output will be in Spanish. I appreciate this contribution from Gregorio, who made the effort to translate the English text files! Any other language translation is welcome, if you want to contribute, please contact me.

When using the software, please make a reference to my paper published in IJAHP about AHP-OS from 2018.

In the last couple of months I shifted my focus from (AHP) software development using PHP to other software developments using Python, yet I will maintain AHP-OS in future. Please let me know if you discover 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. Over the last 3 years donations were barely sufficient to finance my running costs.

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

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.

Concepts, Methods and Tools to manage Business Performance

Dear Friends, dear Visitors,

We released a major update of my free AHP online software. It is now running under PHP 7 and should be noticeable faster than before. Beside some under-the-hood improvement a few new features were added. For more details read my post here.

As a new tool on my website I added a collection of my literature about multi-criteria decision making and AHP. It is available for everyone under the menu point Tools -> Literature. I am using the open source software package Wikindx5. You can browse or search for articles, authors, journals etc. Over time I will fill it up with more article and other research contributions. You can also register as a user and add your own literature to share with others.

Wikindx allows to include citations into a blog. As an example, the following reference is taken from Wikindx:

Many thanks to all donors, supporting this website. Unfortunately, over the last months I didn’t receive many donations. The annual invoice from my hosting provider is expected to come soon, therefore, please continue to support my effort with a small donation, especially when you use my free template 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.

Dear Friends, dear Visitors,

here is the link to the ISAHP 2018 papers and authors. From there you might download my presentation Implementation of an Online Software Tool for the Analytic Hierarchy Process (AHP-OS). It is a short conference paper about my free AHP online software, the complete article – showing was published as

Goepel, K.D. (2018). Implementation of an Online Software Tool for the Analytic Hierarchy Process (AHP-OS). International Journal of the Analytic Hierarchy Process, Vol. 10 Issue 3 2018, pp 469-487

https://doi.org/10.13033/ijahp.v10i3.590

My second contribution was a presentation about Judgment Scales of the Analytical Hierarchy Process –The Balanced Scale. As above, it is a short part of a pubication about AHP scales:

Goepel, K.D. (2018). Comparison of Judgment Scales of the Analytical Hierarchy Process — A New Approach. International Journal of Information Technology & Decision Making, published Dec 11, 2018

https://doi.org/10.1142/S0219622019500044

Over the last couple of months my AHP excel template was updated to show errors for the resulting weights based on the work of Tomashevskii (2014, 2015). You find more details in my post from September 2018. I still have to implement the same calculation into AHP-OS.

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.

Welcome to BPMSG – July 2018

Concepts, Methods and Tools to manage Business Performance

Dear Friends, dear Visitors,

the international symposium on the Analytic Hierarchy Process ISAHP 2018 in Hongkong is just finished, and I gave two presentations in the track Multi-criteria Decision Analysis – Methodology and Theory. One about the AHP balanced scale, and the other about the implementation of my AHP online software AHP-OS.

I’m thankful to the program committee to have received the most innovative idea reward for the paper about AHP-OS.

Some interesting papers were presented, for example Cardinal and Ordinal Inconsistency in pairwise Comparison Matrices by Konrad Kulakowski, or Coherency: an Innovation to Test Data Quality and Reduced Comparisons in the ANP by Orrin Cooper, just to mention two.

I will update you with the link, once the conference proceedings are published.
The conference gave participants also an opportunity for many discussions and the exchange of ideas.

Please continue to support my effort, either with a donation, or a rating to my web posts, which will help me as a feedback to my work.

For now, please enjoy your visit on the site and feel free to leave a comment – it is always appreciated. And don’t forget: Better to be approximately right than precisely wrong.

Dear Friends, dear Visitors,

I wish all of you a Happy and Prosperous New Year 2018!

From July 13th to 15th the International Symposium on the Analytic Hierarchy Process (ISAHP) for Decision Making takes place in Hong Kong. Poster submission is possible from Nov 1st, 2017 to Mar 15th, 2018 and individual paper submission from Nov 1st, 2017 to Mar 6th. Early registration deadline May 15th, 2018. More Information about the ISAHP 2018 can be found on their website.

After my last participation in 2013, I plan to attend the conference in July. If you want to meet me personally, feel free to contact me. I submitted an individual paper about the implementation of my AHP-OS software; it is a short version of my detailed working paper. In additon I will probably submit a short version of my paper Comparison of Judgment Scales of the Analytical Hierarchy Process – A New Approach. This paper was submitted to the International Journal of Information Technology and Decision Making in June 2017, and is under review since then. All attempts to contact the editors and to find out, why the review process takes so long, were unsuccessful.

My AHP-OS software has now reached nearly 6000 registrations since its implementation in 2014. It should be quite stable and without major bugs. Unfortunately, there is still a minor sporadic problem with the storage of pairwise comparisons. It appears in 1 out of 1000 projects that a set pairwise comparisons just disappears. I am still trying to find the reason, kindly contact me, when this happens to you, and let me know the circumstances (It seems to have something to do with the browser and stored session data).

Please continue to support my effort, either with a donation, or at least give a 1 (poor) to 5 (excellent) rating to my web posts, which will help me to get some feedback on my work.

For now, please enjoy your visit on the site and feel free to leave a comment – it is always appreciated.

Concepts, Methods and Tools to manage Business Performance

Dear Friends, dear Visitors,

Over the last three months I did a lot of under-the-hood changes and clean-up on the website to improve safety and user experience. As you may have noticed, the protocol is now https: the web traffic is encrypted using an SSL client certificate. After some tweaking the page performance could be improved significantly, loading time is nearly reduced by half. All pages, including my AHP-OS online software and the diversity calculator, were made mobile friendly, though I don’t recommend to use AHP-OS on a small mobile phone screen.

In addition some new features were added to the AHP-OS online software:

I also wrote a paper about the AHP software implementation, where you can find a description of the structure and all mathematical formulas and references. Please make a reference to this paper, when you use the software in your work to be published.

Kindly support my effort, either with a donation, or at least give a 1 (poor) to 5 (excellent) rating to my web posts, which will help me to get some feedback on my work.

For now, please enjoy your visit on the site and feel free to leave a comment – it is always appreciated.

Concepts, Methods and Tools to manage Business Performance

Dear Friends, dear Visitors,

over the last four months I put in a lot of effort to improve the AHP-OS online tool. With several releases a simplified menu structure and new features were introduced.

Delete individual participant’s inputs from an existing project.
Update a project hierarchy or project description, as long as there is no input.
Evaluate your AHP projects using different AHP judgment scales.
Analyse weight uncertainties based on small randomised variations of input judgments.

The last two features are based on my recent study about the comparisons of different AHP scales. Up to date there was no recommendation, what scales to use, and I found a new approach to analyse and compare the scales based on simple analytic functions. This study is submitted for publication, and I hope it will not take too long, until it is available. You can find some more information already in my posting here.

The feature of analysing weight uncertainties is an innovative way of doing sensitivity analysis: all judgments are randomly varied by ±0.5 on the judgment scale, and for each variation the maximum and minimum out coming priorities are captured. I use 1000 variations, enough to get a relatively stable margin of errors for each weight. It gives you information, how “precise” a weight or ranking is in your specific project.

Again, a big Thank You to all donors! Please note that the website is a non-commercial website for educational purposes.

Dear friends, dear visitors,

Using Google search for my own website, I could see a message like Your website is not mobile friendy. It was really time to update my website theme in order to make it better readable for visitors using their smart phone or tablet.

Now you see the new design using the standard wordpress theme from 2015. I simplified the menu structure to the categories:

AHP Articles – Material and Information about the Analytic Hierarchy Process
Other Articles – Material and Information about Business Performance
Tools – Links to my online tools, like the AHP online system and excel templates
Other – Posts related to other topics
About – Information about the author
Feedback – A place where you can leave your feedback as comments
Contact – A web form to contact me personally via e-mail

I hope with these changes navigation on the site is much easier, and you can find required information in shorter time.

For now, please enjoy your visit on the site and feel free to leave a comment – it is always appreciated.

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.

A couple of months ago I added a Donation button to the website – see below. A big Thank You to all donors! Please note that the website is a non-commercial website for educational purposes.
