Abstract
In recent time, classical methods are used to solve different problems which are faced in medical sciences, engineering, social sciences, etc. Many theories like fuzzy set theory, probability theory, rough set theory, etc..

We study soft set with some definitions and operations, discuss a soft set technique for order preference by similarity to ideal solution (TOPSIS) method and use this method for decision making
Molodtsov proposed the concept of soft set to solve those problems which contain uncertainty in 1999 and defines a soft set as a parameterized family of subsets of universe set where each element is considered as a set of approximate elements of the soft set in the past few years of fundamentals of soft set theory studied by various researchers [2]
Summary
Classical methods are used to solve different problems which are faced in medical sciences, engineering, social sciences, etc. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) introduced in [10] to solve multi criteria decision making problems with different alternatives. They introduced a new decision-making method in [17,18] on interval-valued fuzzy soft matrix.
