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.
