any idea how are we considering max or min status for weight calc? hypothetical e.g. when ranking a car we would want high focus on comfort, safety, mileage and low focus on price. I am not seeing this being considered at all for calc weight.
in general as per the formula we need to us ln only, but calculation i used log, but it does not show a major difference in the output values. i have checked it
@@Vitarka Sir recently I am working for optimal location of solar power plants. So recently I don't know what locations will be my alternatives. I have only criteria right now. I want to know is it possible to find out the weights of criteria without knowing the alternatives by Shannon Entropy method? Please guide. Thankyou
thank so much, Love from Afghanistan
Thank you
Oh my god! this is the most valuable youtube channel. I would like to connect with you.
Good to hear. Mail me gmail

Excellent video. Your use of excel really helped me understand.
Thank you Setheen

That is difference between Objective and Subjective weight methods. You car example was with AHP.
Hi.are log and ln same?? The formulae states ln and the calculation uses log..Please clarify
in general as per the formula we need to us ln only, but calculation i used log, but it does not show a major difference in the output values. i have checked it
how we will conclude which material is optimum to be chosen ???????????
Here this method is used for just for calculation of weights. So it is not the selection of best alternative.
May I ask, Entropy AHP need CI computing or not?
this mean for check consistency (CR) thank you so much
CI computing is for AHP.
Sir thank you, how beneficial and non beneficial attributes are taken into account
It depends on the problem you choose. See my ahp video where I have taken example for car selection
Hai, How you justify in selecting a specific material? and is there any posts on Digital Logic Method?
Specific material what you required is it weight.
Sir, here you are giving weights to alternatives and ranking them. Is it possible to give weights to criteria and ranking of criteria?
Madam, here we the weights are giving for criteria only not for the alternatives.
And ranking will be given for the alternatives.

Yes madam for criteria you can measure the weights.

the formula is with Ln, while you are using log!
Yes, i too did not noticed, thanks for the correction. It should be LN only.
But after changing the value also there is no change in the weight values.
Thanks sir, for such a nice explanation .what will I do if my value comes out negative as criteria?
Very good one, even i did not tried it. but you can use modulus for the formula and then proceed.
What is m, is it no. of variables or no. of experimants
yes, m is number of experiments or alternatives
how we can combine two weight ? I mean weight with entropy and another weight
i think they call it Lambda weight
Can you share me any reference.
@@Vitarka sure, how?
any email or somethings ?
