Some operations and properties of the new model, including subset, equality, union, intersection, and complement are discussed.<br />Further, the basic six definitions, three theorems, and six examples on picture m-polar fuzzy soft sets are explained. Lastly, we construct a new methodology to extend the TOPSIS to picture m-polar fuzzy soft sets (i.e., an application of picture m-polar fuzzy soft sets) in which capable of different objects recognizing belonging to the same family is constructed and illustrated its applicability via a numerical example.https://ijfs.usb.ac.ir/article_7218_04f9ac1ef3be52f5e06ade4df778c5b2.pdf
