Parametric representation of fuzzy numbers (PFN) with derived methods for performing fuzzy arithmetic proves to have better accuracy and similar computational speed to using triangular fuzzy numbers (TFN). These fuzzy numbers (PFN) can be considered a special case of triangular fuzzy numbers (TFN) as they have three additional parameters and their methods for arithmetic operations are further s...

Gypsophila with approximately 150 speciesrepresents the fourth largest genus of Caryophyllaceae and the second genus of tribe Caryophylleae. Iran is the second main center of Gypsophila diversity with 38 species in the world. Considering Gypsophila as one of the most polymorphic genus of the family andalmost half of its taxa distributed in Iran as endemic, thus makes it as a significant genus f...

The fuzzy regression control chart is a functional technique to evaluate the process in which the average has a trend and the data represents a linguistic or approximate value. In this study, the theoretical structure of the “α-level fuzzy midrange for α-cut fuzzy X ~ -regression control chart” is proposed for triangular (TFN) and trapezoidal (TrFN) membership functions. In addition, the real w...
