Fuzzy sets were introduced by Zadeh in 1965 to represent manipulate data and information
possessing non-statistical uncertainties. It was specifically designed to mathematically represent
uncertainty and vagueness and to provide formalized tools for dealing with the imprecision intrinsic to
many problems. However, the story of fuzzy logic started much earlier. Fuzzy system is an alternative to
traditional notions of set membership and logic that has its origins in ancient Greek philosophy.
Research paradigms are rooted in philosophy paradigm, determine the direction of researches; how
the researches reach to the reality, how they answer the questions of the seeking mind … four main
research paradigms distinguished so far are: Positivism, Constructivism, Critical theory and Post
structuralism. These paradigms create not only the mind set of the researcher (what the reality is and
how it can be accessed), but also help him/her use the research methodologies, research methods,
and apply the research findings.
