although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-newtonian calculus. the important point to note is that the non-newtonian calculus is a self-contained system independent of any other system of calculus. since this self-contained work is intended for a wide audience, inc...

Quality function deployment (QFD) is a customer-driven quality management tool that can improve system quality, promote innovation, and enhance the core competitiveness of enterprises. Nonetheless, traditional QFD method has defects in handling experts’ assessments, measuring customer requirement importance, prioritizing engineering characteristics, which affect its efficiency limit application...

in this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. by using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. moreover, we investigate the ...

In this article, the parameter of decision maker’s familiarity with attributes alternatives is introduced for first time in dynamic multi-attribute group making to avoid disadvantages arising from inappropriate grouping makers. We combine it fuzzy soft rough set theory and multi-attribute-grouping obtain a new model, i.e., chaotic multiple-attribute making. Second, we provide an algorithm solvi...
