Multigranulation rough set theory is one of the most effective tools for data analysis and mining in multicriteria information systems. Six types of covering-based multigranulation fuzzy rough set (CMFRS) models have been constructed through fuzzy β

Multigranulation rough set theory is an important tool to deal with the problem of multicriteria information system. The notion of fuzzy β-neighborhood has been used to construct some covering-based multigranulation fuzzy rough set (CMFRS) models th

The pythagorean fuzzy (PF) β-covering has been constructed to extend the fuzzy β-covering, and a type of reducts in pythagorean fuzzy (PF) β-coverings has been proposed based on the union operation. However, for svveral statements, there will be n

In this paper, we investigate the matrix representations of two types of optimistic multigranulation fuzzy covering rough set models. Firstly, some new matrices and matrix operations are presented. Then, matrix representations of multigranulation fuz

An infectious disease model with latent infection is studied, and the basic reproductio n number of the model is obtained When the basic reproducing number is less than 1, the mode l has only one disease-free equilibrium. When the basic reproducing n
