Soft set theory and uni-int decision making. (English) Zbl 1205.91049
Summary: We firstly redefine the operations of Molodtsov’s soft sets to make them more functional for improving several new results. We also define products of soft sets and uni-int decision function. By using these new definitions we then construct an uni-int decision making method which selects a set of optimum elements from the alternatives. We finally present an example which shows that the method can be successfully applied to many problems that contain uncertainties.
