Abstract A soft, rough set model is a distinctive mathematical model that can be used to relate a variety of real-life data. In the
present work, we introduce new concepts of rough set based on soft pre-lower and soft pre-upper approximation
space. These concepts are soft pre-rough equality, soft pre-rough inclusion, soft pre-rough belonging, soft predefinability, soft pre-internal lower, and soft pre-external lower. We study the properties of these concepts. Finally,
we use the soft pre-rough approximation to illustrate the importance of our method in decision-making for
Chikungunya medical illnesses. In reality, the impact factors of Chikungunya’s medical infection were determined.… More >
