TOPSIS multiple attribute decision making method based on three parameters interval number

In order to study the three parameters interval number multiple attribute decision making problems, the three parameters interval number of Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS) multiple attribute decision making method are introduced, the relationship between three parameters interval number operation are set up, the Euclidean distance of the three parameters interval number and positive and negative ideal solution is also defined, by calculating Euclidean distance of each alternative solutions to the ideal point and approximation degrees, according to the size of the approximation degree of implementation in order of alternatives. Finally through the concrete case illustrates the validity and practicability of the method, and to solve the interval number multiple attribute decision making provides a new path.
