The proposed approach overcomes the deficiency of traditional methods, deal with the problems which mixed all kinds of uncertainly, while FCE is introduced to process the information relevant to hotel core competence evaluation. The algorithm is very convenient and easily applicable in practice. Finally, the validity and feasibility of the proposed approach is verified with a case.
