In addition, Fuzzy sets provide the flexibility required to represent and handle the uncertainty and imprecision which result from lack of knowledge and ill-defined information (Yeh & Deng, 2004;Dheena and Mohanraj, 2011). In the last decade, several studies applied fuzzy logic theory to overcome uncertainty and subjectivity in multi-criteria decision making (Chen & Tzeng, 2004;Yeh & Deng, 2004;Dheena and Mohanraj, 2011).…”
