Abstract

Abstract In view of the defects of the civil airport security evaluation and the uncertain factors in it, a new civil airport security comprehensive evaluation method was proposed based on the improved unascertained measure theory. The research shows that: Firstly, the unascertained functions meet the requirements of non-negativity, additivity and normalization, which are the most obvious differences between unascertained mathematical functions and fuzzy membership functions; the unascertained functions of different indicators could be different as well as the unascertained functions of the same index on different grades. Secondly, introducing the concept of entropy, which is based on objective data, greatly reduces the subjectivity of the weight. Thirdly, the credible degree theory is introduced to analyze the comprehensive measurement vector, the range of which is usually between 0.6 and 0.9. Finally, when comes to the security evaluation of multi-airports, if these airports’ security situation belong to one level, comprehensive safety score of each airport could be calculated according to the comprehensive measure vector, on the basis of which the security situation of each airport could be compared. The example shows that the method is simple and effective.This study provides a new way for the security evaluation of civil airport.
