Very good! It helped me a lot to better understand the Fuzzy AHP method. I'm still familiarizing myself with the subject and this video was very enlightening. Grateful!!!
Hello professor, can you tell me How To calculate the fuzzy weight when there are more than one experts in Fuzzy Analytical Hierarchy Process (AHP) with reference? I'm still doing my thesis about this.
Thank for your clear and helpful explaination. I have a question that if there are more than 1 expert giving value, how can i calculate the weight? Thanks.
Prof. Manoj, Suppose you are using this same method in obtaining responses from multiple experts. Suppose then we want to aggregate their inputs using AIP (Aggregate of Individual Priorities). What method will you use? Can we use Geometric mean for that as well? Kindly advise.
Thank you for your video but I have a question. Can I directly use these fuzzy weights for alternative evaluation (using another fuzzy MADM methods) or do I have to normalize the fuzzy weights first? If it's the latter, how can I do that? Note: I still want the weights to be in fuzzy form in my later calculation
Dear Manoj. Your videos are highly inspiring, simple and easy to understand. Just wanted to ask a favour. If you could please upload the reference for the fuzzy scale of relative importance, especially the figure presented at Time 2:22. I shall be grateful. Thanks
you can see my previous videos like TOPSIS in which i have directly taken value of weights, these weights are generally calculated using methods like AHP, FAHP etc.
Hello Professor, thanks a lot for the video. you are explaining one single AHP matrix but what if we AHP data from a survey how should we proceed with the FAHP after ensuring the CR is acceptable. I have data from 16 expert responded to my pairwise comparason
Can you suggest any method to calculate consistency ratio for this geometric mean-fuzzy ahp method? If you can comment on Gogus and Boucher 1998 consistency ratio calculation can be applied in Buckley’s FAHP?
Thanku very much sir for this presentation. But i have one question, how can we calculate consistency in FAHP ??? In Kannan sir's work i have seen that he calculate it, but how, it has not described there..
thanks a lot for this useful video. But i think you forgot to explain about degree of possibility which is very important in FAHP process and id like to lean it too.
How do we calculate the consistency for FAHP? Because now we have 3 values- lower, middle and upper (for triangular membership function). I went through the Buckley's original paper but it didn't mention anything about consistency. How do I prove that the numbers in pairwise comparison are not random and are consistent
The FAHP method given by buckley doesn't give any information about consistency check. Although it is always required to check consistency, when calculating weights using AHP.
If you have a mixture of qualitative and quantitative values of criteria, then all the qualitative values will be converted to quantitative value using a fuzzy 7 point scale or fuzzy 11 point scale.

i think by 20 responded data you mean 20 decision makers. Response from 20 decision makers can be taken individually and it can be combined in to a single value using a formula, i have explained that formula in my fuzzy TOPSIS video. Please watch that video in 2.55 minutes onward..
@@sanjay1982g You mean to say that if the performance value Xij is a numeric value then can we use fuzzy logic. "Basically, fuzzy logic is a precise logic of imprecision and approximate reasoning"- Prof. L.A. Zadeh 2008. so if we already have precise crisp value then no need to use fuzzy logic.
Please explain how to calculate CI and CR for fuzzy AHP. To get weighted sum value in Fuzzy, is the original fuzzified matrix multiplied with the fuzzy weights (not normalized)?
The CI and CR for fuzzy AHP can be calculated- 1st convert the fuzzy number in pairwise comparison matrix to normal ( crisp) number. Then calculate the CI and CR of pairwise comparison matrix. If the pairwise comparison matrix is consistent then the pairwise comparison matrix obtained from fuzzy numbers will also be consistent.
@@manojmathew5287 Thank you for your answer, sir. So we basically turn fuzzy number in the matrix into crisp numbers with use of center of area method? And then calculate CI and CR of this matrix.
@@manojmathew5287 so we turn the fuzzy number, for exampe 2,3,4 to crisp number 3? and then calculate CI and CR with usual formula that used in conventional AHP?
you have to solve all the matrices individually. then at last you may take averages. another way you can check the video of TOPSIS th-cam.com/video/z188EQuWOGU/w-d-xo.html

Sir if I want to consider trapezoidal membership function instead of triangular membership function then what would be the crisp numeric values in terms of fuzzy numbers. For triangular membership function the fuzzy number of crisp value 3 is (2,3,4) then what would be the fuzzy number in case of trapezoidal membership function....pls sir help me...
Im doing a study on trapezoidal membership function. I developed the trapezoidal MF based on triangular MF. But you need to draw a graph first so that you can clearly see the scales overlapping.
In 6.15 minutes
i have taken 4th root because i have 4 criteria in the fuzzified pair wise comparison matrix.
So the nth root will be equal to number of criteria?
