Rough set theory initiated by Pawlak [ 16 ] and soft set theory initiated by Molodtsov [ 15 ] are strong mathematical tools for handling uncertain and vague information. In this study, we bring out some results of soft rough sets ( SR -sets) and topological structure of soft rough sets. We define SR -open set, SR -closed set, SR -interior, SR -closure, SR -frontier, SR -neighbourhood and SR -limit point. Furthermore, we propose an algorithm to illustrate uncertainties in the multi-criteria group decision making (MCGDM) using SR -sets. We utilize another algorithm for modeling uncertainties in multi-criteria decision making (MCDM) using soft rough topology( SR -topology).
