Maji, Pabitra Kumar; Ghatak, Baidyanath On interval-valued intuitionistic fuzzy soft sets. (English) Zbl 1247.03115 Bull. Calcutta Math. Soc. 103, No. 4, 347-358 (2011). Summary: We study the concept of interval-valued intuitionstic fuzzy soft sets. We also introduce here some new operations defined over the interval-valued intuitionistic fuzzy soft sets and established some properties of these newly defined operations on interval-valued intuitionistic fuzzy soft sets.
