Abstract

In this work we define a new type of soft covering upper approximation operator and study its basic

and topological properties. Comparing with other type of soft covering operation, our soft covering

upper approximation is more accurate and have more properties. Based on the new type of soft covering

upper approximation operator, we give a new kind of soft covering based rough sets. Also we present

an example in medicine which determines the risk of prostate cancer. Our aim is to gain results more

reasonable by using upper and lower approximations of a new kind of soft covering based rough sets

and to help the doctor to determine that the patient needs biopsy or not.

Keywords
