摘要
事物的不确定现象包括模糊性和随机性.云模型通过对二者的结合,建立起定性定量的互换模型.相似云及其度量算法的提出使得云模型具有一定的理论价值和实际意义.然而由于云本身的特性,使得算法的计算精度不高、计算消耗较大.因此提出基于区间的云相似度比较算法,对原云相似性算法进行改进.实验证明,该算法在计算精度以及计算消耗上都有较大的优化.
Uncertainty phenomenon includes fuzziness and randomness.Cloud model built an exchange model between quantities and qualities by integrating fuzziness and randomness.The present of both similar cloud and its measurement algorithm made cloud model had some theory value and real meanings.However,the characteristic of cloud made the algorithm with low precision and high consumption of calculation.Based on these,interval-based cloud similar comparability algorithm was brought forward in this paper,which improved original cloud similarity algorithm.The experimental results show that this algorithm optimizes the precision and consumption of calculation.
