      as per the saaty fuzzy it the criteria importance will be 9 only maximum. are you talking about the alternatives.

    What is the interpretation for S and R sir? I read somewhere that they are the utility and regret measure, but I don't really understand what they mean. Could you help me explain that sir? Thank you very much.

    • @Vitarka
      @Vitarka  3 роки тому

      Hi, Utility measure closer to the solution, whereas regret measure is far away from the solution. since vikor is a compromise ranking methodology, it used both nearer to solution and far away from the solution.

      @@Vitarka Thank you for your reply sir, but I'm still a little confused. Sorry if I bombarded you with so many questions.
      1) From what you're saying, utility measure S represents how close an alternative is to the solution; regret measure R represents how far an alternative is from the solution right sir? The "solution" you're saying here is the ideal solution in general (A*), NOT the positive (A+) and negative ideal solutions (A-) like in TOPSIS right? If so, how can an alternative be both near to and far from the solution A*, aren't they just the same thing? I can't still distinguish the meaning between S and R.
      2) I'm also confused by the 2 terms in the formula of Q, what are their meanings? What is the meaning of v?

    • @Vitarka
      @Vitarka  3 роки тому

      Hi, What you are saying in (1) is correct. In our problem, we have to choose best solution and worst solution so that we are not compromising by removing the worst alternatives.
      And V is changing dimension from 0 to 1, if you choose 0 means min and 1 is maximum.

    Dear Sir,
    from where you have taken fuzzy weights?
    Please show that ..

    • @Vitarka
      @Vitarka  4 роки тому +1

      Sir, Fuzzy weights I have collected from the Journal which I have explained in the video. For the Fuzzification, based on your input value you can crisp the value and it is mentioned in almost fuzzy research papers.
