摘　　要：为了验证仿真软件是否达到了给定的可信度,分析了仿真模型校核、验证与确认过程中常用的VVA技术方法的优缺点,针对以太网通信仿真模型的特点,提出了采用置信区间法对仿真模型进行验证与确认.在置信度给定时,通过验证实测与仿真过程中每一点数据的均值差是否都落在置信区间内,判定通信网仿真模型的有效性.实践证明:该方法可以有效的对通信网类仿真置信度进行更为准确的确认,完成仿真软件的评估工作.For the purpose to determine whether the simulation software has achieved the given degree of confidence, the paper studies the virtues and defects of commonly used verification, validation and accreditation methods, and suggests the confidence interval method for affirming simulation model according to the distinguishing feature of the Ethernet. The method is confirming modeling and simulation of communication network by checking whether all differences of mean of the output data of simulation test and practice test are in the given confidence interval. It has been improved by practice that this method could effectively accredit the confidence level of simulation software.
