摘要

云模型可以用于工作状态变化时的可靠性评估，并由定性语言值描述。在利用云模型评价产品可靠性时，忽略了云模型中最典型的样本也存在一定的不确定性。因此，使用云模型来描述最典型样本的不确定性。实验结果表明，采用考虑最典型样本不确定性的云模型进行可靠性评估的结果更接近实际。

A New Method for Reliability Evaluation Based on Cloud Model

Cloud model can be used for reliability evaluation when the working condition is changeable and described by the qualitative linguistic values. It is neglected that the most typical sample in cloud model also contains some uncertainty when evaluate the reliability of products using cloud model. For this reason, a cloud model is used to describe the uncertainty of the most typical sample. The experimental results show that the reliability evaluation result is closer to the reality when using the cloud model that considering the uncertainty of the most typical sample.
