In order to carry out the analysis and quantification for the reliability of CPS, an automatic online assessment method for the reliability of CPS is proposed. It builds an evaluation framework based on knowledge of machine learning, designs an online rank algorithm, and realizes the online analysis and assessment in real time. The preventive measures can be taken timely. And system can operate normally and continuously. Its reliability has been greatly improved. The result of simulation experiments has verified the validity of the assessment method and the broad application prospects.
