Sequence interval-valued fuzzy soft set and its application in decision making

With the developing of science and technology in current years, the theories and tools to tackle the indefinite matters have an overwhelming trend. Nearly all the theories are based on the classical soft set theory that Molodtsov proposed in 1999. This text constructs the concept sequence interval-valued fuzzy soft sets, a comprehensive concept associating the mathematical model interval grey number sequences with the concept of interval-valued fuzzy soft sets. Furthermore, this paper discusses relevant properties and operations about it as well. At last, in order to demonstrate the practical applicability, we deal with the case on decision making.
