Hi thank you for you clear explanation of TOPSIS. I went through the original paper of TOPSIS, but isn't it that the current mathematical formula you are using in step 3. Is only for when all of the criteria are benefit criteria? In the paper there is being explained another form for normalisation for when there are beneficial and non beneficial criteria. As citation from Tzeng, G., & Huang, J. (2011). Multiple Attribute Decision Making: Methods and Applications: Form 2: - For benefit criteria (larger is better), the normalized rating is given by the formula: r_{kj}(x) = (x_{kj}-x^-_j)/(x^*_j-x^-_j), where x^k=max_kx*{kj} and x^-*k=min_kx*{kj} or setting x^*_j is the aspired/desired level and x^-_j is the worst level. - For cost criteria (smaller is better), r_{kj}(x) = (x^-*j-x*{kj})/(x^-_j-x^*_j), and then to calculate weighted normalized ratings by... Then comes step 5 from your video. To understand all of the TeX notation better, just use atomurl . net/math I love to hear your thoughts about this!

Hi Thanks for your appreciation and question...I have normalized both the criteria (Benifit and Cost ) using same formula, this was further neutralize in step 7 in selection of ideal best and ideal worst where I have used different approaches for Benifit and Cost criteria. I hope this will help you.

Sir why you add the weight to the table?
@highermathematicslearning28613 жыл бұрын
Adding weight means I have introduced a new row for weights (These weights are criteria weights)
