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.

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,

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.

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.

A couple of months ago I added a Donation button to the website – see below. Unfortunately, only a very small number of users used it, a big Thank You to them! PLEASE, help to support this website with a small donation. I have no commercial interest, but spend a lot of time, sharing my knowledge for free, and I have running costs to keep the site alive. Thank you in advance!

Dear Friends, dear Visitors,

it’s soon coming to five years that my webpage has been online, and things getting slowly a bit messy … There was a need to clean-up the pages, posts and directories, so that the necessary maintainance will take less time, and future updates are possible. As you should know, this project is done in my free time as a hobby, I still have a full-time job for another couple of years.

Unfortunatly, during the whole process, some links were broken and it will take time to repair. Sorry, when you experience missing images or a broken link. Just let me know using my contact page. I am still working on it and plan to simplify the navigation in order to make it easier for you to find relevant information.

AHP as one category, where you find information about the analytic hierarchy process, will stay in focus. From the start this was the nost frequently visited part of the site, and my AHP excel template slowly reaches 15 thousand (!) downloads. Under the category Articles you find posts about other topics, mainly the concept of diversity, as I was using it for different applications. All more personal related topics under the category Other will move to my new personal blog – Klaus & Lita – running on my own server with topics like multicopter, programming and – maybe – cooking in future.

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

Dear Friends, dear Visitors,

time for another update of my welcome page! Since Chinese New Year in February there have been only two minor updates of my AHP Excel template. On request of many users, it can now handle two criteria. Though there are still a few requests to increase the number of criteria to more than ten, I am not planning to extend the template, as too many pairwise comparisons have to be done, which will be troublesome for the decision makers. It is much better to further breakdown the hierarchy into additional categories.

My AHP online software seems to be quite stable. Beside the regular user administration, I didn’t put in more effort, and the number of active users varies between three and four hundred.

I still get regular feedback via the contact page. It seems that many of my visitors are students, using my tools in their thesis. Sometimes I am asked, whether it is allowed to use them, and the answer is “yes”. As long as you use the software and templates for non-commercial purposes, e.g. education or research, you are allowed to do so. But please give credit to the author, and make a reference to the source.

Since end of last year I started a new hobby, flying remote controlled multi-copter. The header picture of my blog shows the skyline of Singapore, taken with this type of aerial platform. It is a fascinating technology and a lot of fun. I managed to finish my first own-build project, as small miniquad, and also started to develop some simple formulas to estimate flight speed and rate of climb. More to come here!

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

Dear Friends, dear Visitors,

time for a short update on bpmsg.com. Firstly, I wish you a healthy and successful New Year 2015, and for all of you with Chinese background: Gong Xi Fa cai – 恭喜发财, the year of the sheep is coming.

As I had a lot of other activities over the last few months, I was not very active here on my blog here, but the daily number of visitors is still increasing, and I receive feedback and questions regularly, most often about AHP. Thanks for all your comments, and please continue to give me your suggestions and ideas. My AHP online software has now more than 300 registered and active users. Please take note that users, not active for more than three month, will receive an email notification to re-activate their account within two days, otherwise their account incl. all project data will be deleted.

The latest publications, using my AHP Excel template or online software, cover areas like productivity improvement, smart TV human computer interaction, building sustainability and others. I try to keep the list of references up-to-date. Please cite my paper here, if you use my tools and plan to publish your work, and let me know about it.

Surprisingly my post about the Synology DS1513+ network attached storage (NAS) got a lot of readers. Online security seems to be an issue, and making remote online access more secure is indeed an important topic. So I opend the comment field on this post for feedback and questions.

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

Whether you are a CEO of a company, a private person to setup a small individual business or a student, these pages will give you a better understanding of some basic facts and relationships in business.

I have provided them based on my practical experience in working life. I am convinced that you will find some interesting parts, which you can adapt and apply to your business operation.

Maybe, the viewpoint is sometimes different from what you have learned before. As I am an engineer, I am approaching the topic with my engineering background. Don’t be worried, when I sometimes use mathematical expressions. I do it in order to have a more general coverage of the concept, and I am using just simple operations like addition, multiplication, and so on. In most cases you can make all necessary calculations with a simple calculator.

I hope you enjoy the web-site, if you want to comment, feedback or make suggestions, please feel free to do it here.
