Abstract

Notion of soft binary relation is studied here. Some properties of lower and upper approximations with the help of soft equivalence relations are given. Actually, approximations of a subset by a soft binary relation give rise to two soft sets. This new setting is very clear and provides approximations related to every parameter/attribute under consideration. For any subset X, there is an associated fuzzy subset with respect to each parameter. These fuzzy sets are very helpful in decision-making problems. Parametric reduction helps to reduce the size of data. A technique has been presented for this purpose.
