F-rough set was the first introduced dynamic rough set model,and had the characteristics of good compatibility,strong expressive power and good dynamic performance,however most rough set models were not dynamic enough.In order to promote the dynamic development of rough set models and to extend the application of F-rough set,the current situation and development of F-rough sets were reviewed.Three multi-granulation rough set models,including multi-granulation rough set,multi-granularity neighborhood rough set and rough set in multi-scale information system were proved to be expressed with F-rough set.The extension of F-rough set was also investigated.It was suggested that all of other rough set models could be combined with F-rough set so that they would be more powerful to deal with dynamic data,incremental data and tremendous data.The results would improve the dynamization of other rough set models,and would be of benefit for rough set to further integrate into big data era.
