However, in cases where conventional SPC is inadequate, fuzzy statistical process control approaches have been developed which enable more precise statistical process control using fuzzy set theory. In this paper, fuzzy statistical process control techniques have been used to determine whether a 19x39x19 cm pumice brick, which is a product of a pumice brick factory, with fuzzy observation values is under control of the production process. © 2020, TUBITAK.
