In this paper, we review some operations in intuitionistic fuzzy soft multi set theory in different approach and show that the De Morgan’s types of results hold in intuitionistic fuzzy soft multi set theory for these operations in our way. Basic supporting tools in information system are also defined. Application of intuitionistic fuzzy soft multi sets in information system are presented and discussed. Also we show that every intuitionistic fuzzy soft multi set is an intuitionistic fuzzy multi valued information system
