In this paper we have presented an approach to deal with decision making problems. For this purpose we have constructed a fuzzy set, namely D-fuzzy set, for a soft set. This concept of D-fuzzy set will also be used when the information is given in form of weighted soft set, fuzzy soft set or weighted fuzzy soft set. Further we will apply this method when there are more than one observer. We will define such sets as multi-observer soft set, multi-observer weighted soft set etc.
