Abstract
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 Cagman and Enginoglu’s method is very likely to get an empty decision set. Place and Duration of Study: In a recent paper [Caðman, N., Enginoðlu, S., 2010. Soft set theory and uni-int decision making. European Journal of Operational Research 207, 848-855], Caðman 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.
