网络计算系统中的区间直觉模糊信任模型
|
摘要
随着网络计算系统的发展,网络系统的可信度成为制约其发展的关键。针对这一情况,提出一种网络计算系统的区间直觉模糊信任模型。首先,将信任评价的语义标签映射成区间直觉模糊数并对其进行量化,使得模型可以全面的描述语义标签的模糊性和完备性。其次,利用区间直觉模糊数及其精确函数进行信任值计算。最后,对模型算法进行试验仿真,结果表明该模型能有效、合理的对网络进行信任评价并具有一定的理论意义。
With the development of network computer system,the credibility of the network system becomes the key restrictive factor in its development.For this situation,a kind of interval intuitionistic fuzzy trust model of network computer system is proposed.Firstly,semantic tags of trust evaluation are mapped to the interval intuitionistic fuzzy numbers,which then are quantified so that the model can comprehensively describe ambiguity and completeness of semantic tags.Secondly,i interval intuitionistic fuzzy numbers and exact function are used to calculate trust value.Finally,the model algorithm is simulated experimently The results show that the model can evaluate the trust of network effevtively and rationally,which has certain theoretical significance.
