A general fuzzy TOPSIS based on new fuzzy positive and negative ideal solution

This paper presents a fuzzy multiple criteria group decision-making (FMCGDM) problem with the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) based on the new concept of positive and negative ideal solution. Triangular fuzzy numbers (TFN) among decision-making process are used to evaluate the weighted different alternatives versus various. Additionally, in this paper we compared this algorithm with three algorithms, obtained interesting result and showed this result in two tables. This result indicates that our method is better than other algorithms.
