Thank you Dr. Mathew for your explanation for the weighted Sum Method...

[selenabalbinosantos]

What a straightforward explanation. Thanks, my man!

Hats Off Mathew.... Great work in such a short time period

I had never got this till this day that I have my exam 🙏👏 merci beaucoup.

@Manoj Mathew, thank you so much for the detailed explaination. I have a question. Can I assume weights for the criterias?? Thanks in advance :)

Hello, thank you for uploading this educational and helpful video! I just found a mistake at 4:44. Mobile 4 must be 0.7567 instead of 0.7067.
I have a question. Which resource do you think the best to learn Multi Criteria Decision Making by reading? I usually prefer reading

I think summing was wrong. Multiplying all criteria points at the end would be more accurate. Because we rated criterias according to each other.
I mean lets say we have 2 phone:
One of them's price is 400, performance is 100; another one's price is 800 and performance is 190.
If we sum; first alternative's point is 2+1 =3
Second alt: 1+1.9 = 2.9
And it means first alternative is 3/2.9 times better but this is wrong.
If we multiply it the result will be:
First alt : 2×1 = 2
Second alt : 1×1.9 = 1.9
And it says first alt is 2/1.9 times better than second. Why this one is true?
Because when u equalize the costs at 800;
First alt: cost 800 perf 2
Second alt : cost 800 perf 1.9
And it says first alternative is 2/1.9 times better than second one, not 3/2.9
Summing is completely wrong. If we rate criterias according to each other, we should multiple them to see which one consists higher positivity

Hi, can you tell me please what is the name of this technique where you choose the performance value and then divide. Or can you please tell me some articles to read about this?

[iangeitner]

Wonderful video, thank you for sharing.

[amitstorm]

This normalisation matrix can we use in Fuzzy TOPSIS for multiplication with the fuzzy weights
