Vectors between a decision and its positive and negative ideal points under twotuple linguistics are defined and a bi-directional projection close degree calculation formula based on positive and negative ideal points is proposed to solve the problem that traditional projection operators cannot figure out the two-tuple linguistics sequence when the projections are the same.The solution of bi-directional projection close degree with the given attribute weight is studied.Finally,a specific case study proves the validity and feasibility of the proposed method.
