Abstract
This paper is concerned with a technique for order performance by similarity to ideal solution (TOPSIS) method for fuzzy multi-attribute decision making, in which the information about attribute weights is partly known and the attribute values take form of triangular fuzzy numbers. Considering the fact that the triangular fuzzy TOPSIS results yielded by different distance measures are different from others, a comparative analysis of triangular fuzzy TOPSIS ranking from each distance measure is illustrated with discussion on standard deviation. By applying the most reasonable distance, the deviation degrees between attribute values are measured. A linear programming model based on the maximal deviation of weighted attribute values is established to obtain the attribute weights. Therefore, alternatives are ranked by using TOPSIS method. Finally, a numerical example is given to show the feasibility and effectiveness of the method.
