摘　　要：对确定系统相似性的理论和应用研究已经取得了不少成果;并且随着概率论与数理统计的快速发展,其在系统工程方面的应用也有了较大的突破,这使得仅仅研究确定性系统是不够的,文章在利用概率论的思想给出随机系统的相关定义基础上给出随机系统相似性的定义及其度量,并给出了实例的讨论。On the one hand,many results have been achieved in research of theory and application of similarity of determined systems.On the other hand,with the rapid development of probability and statistics,its application in systems engineering has also been a major breakthrough,So it is not enough for use only to study the determined systems.By using the idea of probability to give out the definition of random system will be the first problem of this article.Furthermore,both definition and its measure of random system,s similarity will be given out,an example is discussed as well.

关 键 词：随机系统 随机变量 相似性
