sustainable development goals and homelessness

The united nation’s sustainable development goals encourage countries to solve many social problems‎. ‎one of these problems is homelessness‎. ‎we consider those goals which are most pertinent to homelessness according to cite{13}‎. ‎we rank countries with respect to the‎  achievement of these goals‎. ‎we use fuzzy similarity measures to determine‎ ‎ the degree of similarity between these rankings‎. ‎we use three methods to‎ ‎ rank the counties‎, ‎namely‎, ‎the analytic hierarchy process‎, ‎the guiasu‎ ‎ method,‎ ‎and the yen method‎. ‎overall scores of categories in some basic‎ ‎ research papers pertaining to sustainable development goals were obtained by‎ ‎ using multiplication of the scores of the category’s targets‎. ‎multiplication‎ ‎ was used to agree with the philosophy that in order for a high score to be‎ ‎ obtained,‎ ‎all targets must have a high score‎. ‎to support this philosophy in‎ ‎ the decision process‎, ‎we use the $t$-norms bounded difference‎, ‎algebraic‎ ‎ product,‎ ‎and standard intersection as experts‎. ‎we also suggest a way the‎ ‎ techniques used here can be extended to nonstandard analysis‎.
