Abstract: According to the concept of hybrid parallel space, we propose hybrid parallel rough sets based on hybrid parallel equivalence operators in pansystems, using the transformation thought of pansystems theory and the method of equivalence relations to approximate the target concept. Then, by discussing the basic properties of the hybrid parallel rough set model, it is proved that the model is the generalized expression form of the pansystems rough set. An example is shown that the particles of different knowledge bases are generated under the action of different hybrid parallel equivalent operators, which provides a new approach for the further research of granular computing.

Key words: hybrid parallel rough set, hybrid parallel equivalence operator, pansystems series-parallel model, rough set, granular computing
