TOPSIS WORKSHEET


TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a decision making technique that fits between the qualitative Pugh Matrix and quantitative SDI Matrix approaches. TOPSIS is a Goal-based approach for finding the alternative that is closest to the ideal solution

The basic concept of this method is that the selected Design Options should have the shortest distance from the ideal solution and the farthest from the negative-ideal solution (in a geometric sense). The Euclidean distance approach is used to evaluate the relative closeness of each Design Option to the Ideal solution.

TOPSIS approach:
  1. Create matrix with Design Options and Criteria
  2. Assign Importance to Criteria
  3. Enter Design Option data for each Criteria
  4. Assign goal direction (Minimize or Maximize)
  5. Compute and Evaluate Scores

TOPSIS assumes that each Design Option wants to either be maximized or minimized, so the positive-ideal solution for a Criterion that wants to be maximized is the maximum value of all the design options considered and the negative-ideal solution is the minimum values of all the design options considered.
