A Conformable Fractional Discrete Grey Model CFDGM (1,1) and its Application

An accurate forecast of the area drought disaster is vitally important for government to take appropriate measures prevent disaster. In current study, a new conformable fractional discrete grey model applied study trend affected by disasters. Firstly, model, abbreviated as CFDGM(1,1), proposed with definitions operator and classical GM(1,1) model. Then recursive expression time response function obtained basic form, linear system parameters are confirmed least squares method. Further, Salp Swarm Algorithm chosen determine optimal order. Finally, studied others, where results show has good performance among these models.
