Proceedings of FSDM 2015. Fuzzy logic is widely used in machine control. The term fuzzy refers to the fact that the logic involved can deal with concepts that cannot be expressed as either true or false, but rather as partially true. Fuzzy set theory is very suitable for modeling the uncertain duration in process simulation, as well as defining the fuzzy goals and fuzzy constraints of decision-making. It has many applications in industry, engineering and social sciences.This book presents the proceedings of the 2015 International Conference on Fuzzy System and Data Mining FSDM2015, held in Shanghai, China, in December 2015.
