摘要
This paper aims to propose the notion of Type-1 single-valued neutrosophic complementary beta-neighborhood (briefly, Type-1 SVN complementary beta-neighborhood) and use it to introduce a novel class of 1-single-valued neutrosophic beta-covering rough set (briefly, 1-SVN beta-CRS). Then, we will merge the 1-SVN beta-neighborhood and 1-SVN complementary beta-neighborhood to create new two models of 1-SVN beta-CRS. Furthermore, we will discuss the relationships between the present work and Wang and Zhang's work. For further study on Type-2 Wang and Zhang's models, we will define the 2-SVN complementary beta-neighborhood and use it to present a novel class of 2-SVN beta-CRS. Also, we combine the 2-SVN beta-neighborhood and 2-SVN complementary beta-neighborhood to investigate the new two models of 2-SVN beta-CRS. Lately, we will demonstrate two illustrative examples as real problems to show the differences between two of our approaches and Wang and Zhang's approach.
