By far the clearest practical explanation of AHP. Now I have to go back to the math behind for a more complete and exhaustive understanding of this powerful MCDA technique.

What a great explanation of the maths of AHP. It's really clear. In the real-world, however, the maths is not so important. AHP, in real-world decisions, is about getting your stakeholders aligned. Decision-making is usually a team-sport and getting stakeholders aligned properly and having a strong structure to the evaluation process is what leads to better decisions, more buy in and increased decision velocity. If you're interested in how AHP in real-life situations, I'd suggest this video. It's a real decision consultant talking about a real decision ($200m decision) and he talks about all three value points - better decision, faster decision, more buy-in. This not a function of the maths (tho' it can't be done without the maths), it's a function of a collaborative, structured discussion and decision process. kzread.info/dash/bejne/l52qusGnosrNqrQ.html I hope this helps those who are new to AHP.

Hi, I have some problem understanding Ws and Consistency vector mentioned in KZread video AHP1&2. In the videos of AHP1 & 2, the formula to calculate Ws is C x W And the values of Ws of material costs given in AHP2 are 0.286, 0.515, 0.839, 3.090, 1.908, 0.210 The value of C of material costs before normalized are 1, 0.333, 0.2, 0.111, 0.143, 3 In AHP1, the W of material cost is 0.047 If I calculate based on the above values, the values of Ws would be 0.047, 0.156, 0.0094, 0.005217, 0.006721, 0.141 The values of Ws calculated are very different from the values of Ws provided in AHP2. Is my calculation correct? Also, if Ws = C x W, and {Consis} = dot product of Ws x 1/W Then isn’t that {Consis} = C x W x 1/W = C Would like to seek for help in clarifying the above.

Thanks for your video. This is good for mechanical application of AHP: you explain the calculation for each passage. However, you do not explain the meaning of each calculation, so interpretation is not easy. For example, why should one sum the element of each column? What does the resultant number represent and why? Also, why should one normalize? And why does averaging by row should provide the importance degree of each criterion? Why does CI has n-1 at the denominator? And what does lambda mean and what does lambda minus n represent?

To those who wondered about where the values from C came from, she mentioned matrix [C] on track 7:00 in her previous video, AHP Part 1 (remember, it's NOT the normalized one). Just take that matrix MINUS the sum-row, multiplicate it with vector [W] and you will get Ws. Another thing is thank you so much for your time, Ma'am! I have seen both Part 1 and 2 and could not find any AHP-video better than this!

Please, could you explain more with example (w* first value how she calculated it )in same her example if possible how she calculate the C
@theresahanvunguyen16773 жыл бұрын
@@zainabal-baldawi9768 She started explaining matrix C from 4:00 in AHP Part 1. You choose the numbers in this matrix yourself based on your own evaluation of two and two of the criteria. She's categorized the levels of criterium importance into three right below matrix C, so here you can understand why she chose certain numbers in C. She chose Mfg Cost to be moderately more important than Mat Cost with 3.00, thus Mat Cost is moderately less important than Mfg Cost with 0.33. So actually you only need to choose numbers half of C and use this to calculate the rest of C, so 1/3.00 = 0.33. Work with the number 1s standing diagonally in C and divide by the number below it to get number to the right of it. For checking, do the reverse which is multiplying 1 with the number to the right of it to get the number below it. You may have to draw one vertical line and one horizontal line through the numbers below and to the right of 1 in C to see clearer. You'll see the diagonal pattern because the criteria stand in the same order vertically downwards and horizontally rightward. Is this clear, Ms. Allawi?

Helpful, but would have been much more so if the presenter had selected the proper slide to show when discussing what's on a slide. Also, a pointer showing which detail of a slide was being discussed at the moment would have been quite helpful. As it was, I was constantly searching around the slide shown to see what it was he was talking about at the moment. This caused my attention to drift from what was being said. In other words, the end product would have been greatly improved had it undergone proper DFMEA and PFMEA. Thank you.
