Hello World

It's been a while that we established free TOPSIS online calculator on Decision-Radar.com. If you don't know what TOPSIS is, I copied paragraph below from Wikipedia.com:

The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is a multi-criteria decision analysis method, which was originally developed by Hwang and Yoon in 1981 with further developments by Yoon in 1987, and Hwang, Lai and Liu in 1993. TOPSIS is based on the concept that the chosen alternative should have the shortest geometric distance from the positive ideal solution (PIS) and the longest geometric distance from the negative ideal solution (NIS).


TOPSIS is a great way if you stuck on decision making. It doesn't matter if you are an student or a person who stuck on making decisions, TOPSIS methods and especially our free online TOPSIS tool will assist you. There are many TOPSIS methods, but for now, our product supports ELECTRE and simple TOPSIS.


If you are going to buy a car, house, cell-phones and etc. TOPSIS can help you, it's an easy, proven and scientific way to help you to make a decision in an scientific way.

What does Decision-Radar offer?

  1. Easy user-interface
  2. Support both TOPSIS and Electre.
  3. Give you the final results.
  4. Give you output matrix results(decision matrix).

Why you might use it?

Because it's free and easy to use.

What will we offer in the future?

Well we haven't decided yet, but we look forward to support TOPSIS AHP method and some few cool features.

For the geeks

I wrote this product in Python 3 and I'm using numpy.


In the video below you can see how easy it is, a simple TOPSIS method example:
