摘要: 针对网构软件信任评估的不确定性、模糊性及无法精确描述和验证等问题,提出一种用于网构软件信任评估的模糊综合评判方法,在确定各因素权重时引入信息熵理论,克服传统方法因主观分配权重而导致信任评估模型动态自适应性不强的缺点。实例分析结果表明,该方法有效可行。

Abstract: Aiming at these problems of Internetware trust evaluation such as uncertainty, fuzzy and not being able to accurately described and verified, a fuzzy comprehensive evaluation method for Internetware is proposed which determines the various factors weights. It introduces information entropy theory. The method can overcome the shortcomings in determining the weight by the subjective judgments method, and improve dynamic adaptability of trust evaluation model, which is not strong enough as a result of subjective weight distribution by traditional methods. The case study shows the feasibility and effectiveness of the method.

Key words: fuzzy comprehensive evaluation, information entropy, entropy weight coefficient, trust evaluation, Internetware
