A Survey on the Application of Cloud Models in the Reliability of Cloud Environments

In solving the ambiguous phenomena existing in life, qualitative concepts and quantitative values need to be converted to each other, so a qualitative-quantitative uncertainty model is needed. Cloud model is a kind of uncertainty model for qualitative-quantitative conversion proposed by academician Deyi Li. This paper firstly introduces the background and basic definition of cloud model, summarizes the progress of application of cloud model in controller, data mining, genetic algorithm and other fields, and proves that cloud model can play an important role in qualitative-quantitative conversion problems in different fields. Finally, the advantages and application methods of cloud models in the reliability of cloud environment are introduced.
