Selecting Visualization Alternative Based on Fuzzy Multiple Attribute Lattice Order Decision Making Method

摘要

This research develops a fuzzy multiple attribute lattice decision making (FMALDM) model with preference information on alternatives based on lattice theory, which is used for selecting a suitable visualization alternative for tourism. The information on attribute weights is unknown and the attribute values are trapezoidal fuzzy numbers. The definition of the deviation degree of trapezoidal fuzzy number is given. A formula based on deviation degree for deriving attribute weights is presented, then the comprehensive weight is given combined with the subjective weight. According to the center of the trapezoidal fuzzy number, the order of all programs is given based on calculating the distance sum from the center of the attribute values of various programs to the optimal solution. The method can sufficiently utilize the normalized fuzzy evaluation information and meets the requirements of decision-maker, and can also be performed on the computer easily. Finally, combined with the case of enterprises in the choice of strategic alliance, a numerical example is given to show the feasibility and effectiveness of the proposed method.
