摘      要：The preference analysis is a class of important issues in multi-criteria ordinal decision *** rough set is an effective approach to handle preference *** order to solve the multi-criteria preference analysis problems,this paper improves the preference relation rough set model and expands it to multi-granulation *** is also an important issue in the field of decision *** the cost into consideration,we also expand the model to the cost sensitive multi-granulation preference relation rough *** theorems are represented,and the granule structure selection based on approximation quality is *** experimental results show that the multi-granulation preference rough set approach with the consideration of cost has a better performance in granule structure selection than that without cost consideration.
