Evaluation of alternatives applying TOPSIS method in a fuzzy environment
研究了模糊环境下的多属性决策问题，将TOPSIS方法扩展到模糊环境，用三角模糊数描述权重和评分，并通过计算实验比较了三种模糊TOPSIS变体的结果。
Abstract The paper analyses the problem of multiple attribute decision‐making (MADM) under fuzzy environment. In some cases the crisp value is inadequate to model real‐life situations. For this reason some fuzzy MADM methods have been developed. The extended TOPSIS (Technique for the Order Preference by Similarity to Ideal Solution) to fuzzy environment is presented in the current paper. Weights and ratings of each criterion are described in triangular fuzzy numbers. The relative closeness to the ideal solution of each alternative is calculated applying different approaches that were presented in different scientific papers. A computational experiment is presented to compare the results of a multiple attribute analysis that uses three modifications of fuzzy TOPSIS method in a particular situation.
