Journal Article 2023 11 11 The pattern of embedding of rough approximation lattices defined by a reflexive relation in its Dedekind-MacNeille completion of rough sets system is taken up for study in this work.<br />The reflexive relation R for which the Dedekind-MacNeille completion of rough sets system defined by R is the pasting of its rough approximation lattices is characterized. Some properties of the<br />Dedekind-MacNeille completion of rough sets system defined by a<br />reflexive relation R are also discussed.
