Research and application of multiple attribute decision making based on triangular fuzzy ideal points

In multiple attribute decision making, attribute value and attribute weight cann´t be often given the exact value, they are sometimes given in the form of fuzzy numbers. This paper researches a kind of multiple attribute decision making in which the attribute value and attribute weight are given in the form of triangular fuzzy numbers, proposes a new decision making method, defines the positive and negative ideal alternatives of triangle fuzzy number, as well as the distance between the various alternatives and the positive, negative ideal alternatives, through calculates the nearness degrees between various alternatives and ideal alternative to carry on sorting the alternatives. Finally, this method is applied in choosing investment alternatives to develop new product, the example shows that this method is validity and feasibility.
