Abstract: Aiming at the linguistic multi-attribute decision making, this paper proposes multi-attribute decision making method based on two-tuple linguistic information processing and rough set. The decision-making information form is established using standard linguistic assessment information, and the objective weights are calculated by using attribute significance degree and information degree. The subjective weights are calculated by using the weighted averaging operator for two-tuple linguistic; subjective weights and objective weights are integrated into comprehensive weight  based  on the decision maker’s preferences; two-tuple linguistic rough operator is defined by combining the known information aggregation operator and the normalized  linguistic appraisal information, which is transformed into  the form of  two-tuple linguistic; one example is given to illustrate the application of two-tuple linguistic rough operator.

Key words: two-tuple linguistic, rough set, multi-attribute decision making
