Soft set theory and uni-int decision making

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.
