چکیده
The aim of this paper is to study the properties of t-cut set, strong t-cut set, t-quasi-cut set, strong t-quasi-cut set and ∈ ∨q-cut set of a fuzzy set μ. For any intuitionistic fuzzy A =< μA, νA > and α, β ∈ [0, 1], we define and study the properties of upper (α, β) cut setA(α,β), strong upper (α, β) cut setA(α, β) ̇ , lower (α, β) cut set A, strong lower (α, β) cut set A (α, β) ̇ , upper (α, β)-quasi-cut set A<α,β>, strong upper (α, β)-quasi-cut setA< α, β > ̇ , lower (α, β)-quasi-cut setA, strong lower (α, β)-quasi-cut set A < α, β > ̇ and ∈ ∨q-cut set.

Construction of α-cut fuzzy X control charts based on standard deviation and range using fuzzy triangular numbers
Control charts are one of the most important tools in statistical process control that lead to improve quality processes and ensure required quality levels. In traditional control charts, all data should be exactly known, whereas there are many quality characteristics that cannot be expressed in numerical scale, such as characteristics for appearance, softness, and color. Fuzzy sets theory is a...
