Összefoglaló	Soft Set Theory is a mathematical framework for handling uncertainty and imprecision through parameterized families of sets. Introduced by Dmitriy Molodtsov in 1999, it provides an approximate description of objects in a universe by mapping each parameter in a chosen parameter set to a crisp subset of that universe. Unlike probability theory or fuzzy sets, soft sets require no membership function or probability distribution, making the framework free from the inadequacy of existing uncertainty tools when sufficient data are unavailable.	Granular computing is a problem-solving paradigm that processes information in 'granules' — clumps of objects drawn together by indistinguishability, similarity, or functionality — rather than at the level of individual data points. Articulated by Lotfi Zadeh in 1997 as fuzzy information granulation and developed into a broad framework, it provides a unifying umbrella over fuzzy sets, rough sets, and interval methods, letting analysis move to whichever level of detail a problem actually requires.
