摘　　要：针对信息安全评估的繁复性和评价信息的模糊性,引入拟熵权模糊综合评估法,克服熵权法计算量较大和算法有时不可行的缺陷,为此类问题的求解提供一个新的思路和方法。为便于应用,给出算法流程图。最后结合实例,将拟熵权与熵权、Delphi法赋权的模糊综合评估结果进行比较,表明拟熵权法的隶属度最高。通过编制Matlab程序实现信息安全评估的半自动化,以减轻繁复的评估工作。In view of the complexity in the evaluation of information security and the fuzziness of the information to be evaluated, this paper introduces the quasi-entropy weight fuzzy comprehensive evaluation method that avoids the large calculation amount in the tradi- tional entropy weight method while overcomes the drawback of algorithm sometimes being not feasible. The method initiates a new idea to solve this kind of questions. For the convenience of application, the paper presents the algorithm flow chart. And further, combined with practical examples the results of quasi-entropy weight method, traditional entropy weight method and Delphi weighting of fuzzy comprehensive evaluations method are compared in details. It follows that the membership degree of the quasi-entropy weigh method are the highest. By using the Matlab program, the authors realize semi-automation of the information security evaluations and lighten the complicated evaluation work.
