International Journal of Neutrosophic Science IJNS 2690-6805 2692-6148 10.54216/IJNS 2020 2020 An Analysis on Novel Corona Virus by a Plithogenic Approach to Fuzzy Cognitive Map Department of Mathematics, Sri Sivasubramaniya Nadar College of Engineering, Chennai, INDIA admin admin Department of Mathematics, University College of Engineering – Kancheepuram, Kancheepuram,INDIA S S.Poomagal Department of Mathematics, Sri Venkateswaraa College of Technology, Sriperumbudur, INDIA G G.Kuppuswami Laboratory of Information Processing, Faculty of Science Ben MSik, University Hassan II, Casablanca, Morocco Said Broumi   In this paper a Plithogenic approach to Fuzzy cognitive map has been proposed to analyse the impact of novel corona virus.Contradiction degree is an advantageous feature of Plithogenic sets which highly deals with the uncertainty and it substantially increases the accuracy of results. In this research, a new approach is proposed to accumulate the opinions of experts.Using contradiction degree between opinions of experts and plithogenicoperator,the connection matrices obtained from distinct experts are aggregated to improvise a degree of uncertainty. An Analysis on covid-19 (causes, spread and precaution) is done based on the proposed methodology.   2020 2020 62 75 10.54216/IJNS.0110201
