A Note on “Soft Set Theory and Uni-int Decision Making”

Aims: The aim of this paper is to propose a note on “Soft set theory and uni-int decision making”.

Study Design: In this note, we point out by an example that Çagman and Enginoglu’s method is very likely to get an empty decision set.

Place and Duration of Study: In a recent paper [Çaðman, N., Enginoðlu, S., 2010. Soft set theory and uni-int decision making. European Journal of Operational Research 207, 848-855], Çaðman and Enginoðlu constructed an uni-int decision making method which selected a set of optimum elements from the alternatives.

Methodology: Furthermore, we present a new approach to soft set based decision making

Results: We give some illustrative examples.

Conclusion: Two numerical examples illustrate the practicality and effectiveness of the developed approach.
