In this paper, a novel coronavirus infection system with a fuzzy fractional differential equation defined in Caputo’s sense is developed. By using the fuzzy Laplace method coupled with Adomian decomposition transform, numerical results are obtained for better understanding of the dynamical structures of the physical behavior of COVID-19. Such behavior on the general properties of RNA in COVID-19 is also investigated for the governing model. The results demonstrate the efficiency of the proposed approach to address the uncertainty condition in the pandemic situation.

新型冠状病毒的模糊分数阶模型。

本文开发了一种新型冠状病毒感染系统，其具有卡普托意义上定义的模糊分数阶微分方程。通过使用模糊拉普拉斯方法与 Adomian 分解变换相结合，获得了数值结果，以便更好地理解 COVID-19 物理行为的动力学结构。还针对控制模型研究了 COVID-19 中 RNA 一般特性的这种行为。结果证明了所提出的方法在解决大流行情况下的不确定性情况方面的效率。
