Real world applications are dealing now with a huge amount of data,
especially in the area of high dimensional features. In this article, we depict the
simply*upper, the simply*lower continuous, we get several characteristics and
other properties with respect to upper and lower simply*-continuous soft multifunctions. We also investigate the relationship between soft-continuous, simply*-
continuous multifunction. We also implement fuzzy soft multifunction between
fuzzy soft topological spaces which is Akdag’s generation of the notion. We
are introducing a new class of soft open sets, namely soft simply*open set deduce
from soft topology, and we are using it to implement the new approximation space
called soft multi-function approach space. Simply*space for approximation based
on a simply*open set. The world must adopt modern studies in order to confront
epidemics. Accordingly, we presented a new decision proposal in this article,
compared our proposed approach to the soft relationship introduced by approximation of Xueyou, and concluded that our approach is better. We also used our
proposal in the medical application that was studied in this paper
