Fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a multi-criteria decision-making method that incorporates fuzzy logic to handle uncertainty and vagueness in the evaluation of alternatives. By utilizing fuzzy sets, this approach allows for more flexible assessments of criteria, enabling decision-makers to weigh options based on their preferences and the inherent imprecision of information. This method is particularly useful in situations where crisp data is insufficient and helps in ranking alternatives effectively.
