Thanks for all the help, super useful. Just wish you would ctrl+c and ctrl+v lol Sooooooooooooo many ways this could be done faster, but I guess for teaching purposes this approach works
You can choose randomly, but try to choose equally, I mean u should give equal weights to all the matrics. The overal weights must equal to 1. Besides, sometimes, one of the matric demand heigher weight due to its importance, so can divide accordingly.
The value depends on the user. So basically you highlight how import each criteria is to you in a total of 1 or 100% i.e the addition of all the weightage must not exceed 1 or 100%. From the example the user is more concerned about the price another user might be more concerbed about the storage space so he could give it a weight of 0.40 (40%)
Hi Sir, Thanks for sharing, I have a question that. comparing (C1 vs C2) and we get response from 10-experts. Then we need aggregation to obtain single value? and need Geo-mean?. waiting for the response ?
price is a non beneficial criteria as we desire to have minimum price. The best alternative will have minimum price. but in case of storage space we need to have maximum value. the best alternative should have maximum value of storage space.
Hello, I would like to ask you about three points: 1. If I use the same numeric values of criteria, alternatives and weights in ELECTRE and PRO-METHEE methods, is-it must get the same values of ranking? 2. In TOPSIS method, can I apply it without weights? just using the alternatives and criteria?? 3. If I am using the same numeric values of criteria, alternatives and weights in ELECTRE and PROMETHEE and apply the same numeric values of criteria and alternatives on TOPSIS I will get the same values of ranking for the three methods? Many thanks for your response.
Respected Prof. Manoj Mathew, can you tell if this method can be used if we have 100 different items (like mobile phones)? Can we use it to rank higher number of alternatives, say between 100-300? Please tell if this is possible with Excel...if not, what software should we use?
Although you can perform it in Excel, but It will be hectic to solve huge decision matrix in Excel. Please use octave software to solve the problem. I have developed octave code for TOPSIS, you can access it from my webpage.
If you are taking about typical optimization in which you want to determine the dependent variable for optimum objective function value then you should use optimization techniques( there are several depending upon the problem). But if you are looking to find the best out of available, then go for MCDM.
Dear sir, i have one question.. the calculation you made to find the best mobile, can we make a opposite ? let say, we want to find the best criteria for the mobile by using TOPSIS? for instance, among these criteria which are cost, storage, camera and looks which one is the best? Sir, please answer me, i really need answer from expert like you sir.
there is a mistake the weight of the camera is 0.15 and it looks like 0.05. but, you have taken weight 0.25 for both camera and looks which is wrong.please correct it
Tazii, the weights can be calculated based on the requirement generally it is calculated using other methods like analytic hierarchy process or entropy weight method. i will explain those methods in my upcoming videos
Dear Manoj, thanks for your amazing videos! Shouldn't it be 1 - the Normalization function though for the first criterion (= non-beneficial criterion)? Thanks!

you are legend Manoj.
this video is simply awesome, love the way you explained it.
I got this tool during my MSc. Good template indeed!
Thank you Manoj, super clear and useful video!
Thank you very much! The exercise was quite clear and useful.
Dear Manoj, Thanks a lot.
please sir, suggest a book which contained most MCDM methods in research point of view...
Very good Manoj.
How can we choose the weight on the first row ? 0.35, 0.25,0,15, 0.15 ? We ourshelve to choose ?
Please have you got the answer?
@@aminuinuwadarma8407Use Analytic hierarchy process to calculate weights

owh... the link provided.. thanks sir.. thanks for the excel file
Thank you sir but how Can we calculate the weight ?
Greeaat video very helpful
Sir, if for my fyp , do i have to take 5 example only? What if my project scope needs more than hundreds 😭😭😭 do i have to calculate like this?
Hi. Thanks for the video tutorial. However, I wonder how you got the values for weightage of Non Benf., Benf., Benf., Benf.? What do those mean?
The value depends on the user. So basically you highlight how import each criteria is to you in a total of 1 or 100% i.e the addition of all the weightage must not exceed 1 or 100%. From the example the user is more concerned about the price another user might be more concerbed about the storage space so he could give it a weight of 0.40 (40%)

@@manojmathew5287 Thanks for your explanation , you do gave me a big favor.
can u please share trapezoidal fuzzy number
calculation.
Can you tell me which research paper you have referred for TOPSIS.
Can I take all the columns as non beneficial .
Because as for my requirement I want minimum value for each column
Yes you can take. Its up to the decision maker
@@manojmathew5287 thank you sir ,
If I take all as non beneficial,is there any change in formula's

Hello sir can you please tell how to normalize when we have only two values means only two data values for one parameters or criteria
Excellent sir, brilliant and very helpful for my studies.. sir can can you give me this sample excell ? Your consideration is much appreciated.
whether the sum of the weight of criteria must be 1, as in your example?
yes the sum of weights should be 1, if in any case its not 1 then you should normalize it so as to make it 1.
How the weight give initial sir...?
hello sir. Why do I get a value of 0 for si+ and si- 😅
Thanks for the video. Mobile no. 3 has highest price. How can you justify that optimal solution?
dear sir. matlab code topsis is very excellent. the result is same as excel. Do you have code matlab code for grey relational analysis
Thanks alot , very help full
Sir if we increase the criteria, then also weightsge should equal to one.
Dear Mathew, please when dealing with a large data set, for example, 100, how do we compute it? I anticipate a swift response. Thank you.
You can use OCTAVE programing to solve a problem with large set of data. Please brows through my web page for getting the OCTAVE code
clear steps on sensetivity analysis
Is it not same like GRA?
Thanks for support!!
thanks for video
Nice one sir, pls I need the excel template for Electre III and Mavt
very helpful. Thank you sir

you need to understand excel so it is no big deal. just study advanced excel.
is any MCDM method for optimizing machining

YOU HELP ME ALOT
nice video
Thank you very much.it was so helpfull .
very helpful. Thanks
I really liked the way you explained this but I really need a help to explain how did we get the weighted values ( .35, .25, .25 & .15)
It is a data, you can choose all the four datas that you want, but the total weight of the 4 datas should be = 1.
Sir what is the reason behind it why the sum of weights should be equal to one? Plz reply soon tomorrow I have to present it...
Thank you very much Sir

dear Mathew sir,
Please elaborate, how the value of 250,200, 300 has come in price/cost column?
need immediate answers as I am working on this topics.
are those numbers always supposed to be under 1
Sir?
