Abstract :The new priority in the grey modelling is to build new models that have more accurate forecasting power than the previous ones. This paper aims to develop the prediction performance of the existing continuous grey models. Therefore, a novel continuous grey model insert ignore into journalissuearticles values(OCCFGMinsert ignore into journalissuearticles values(1,1);); is proposed with conformable fractional derivative. The numerical results of three case studies show that the novel model`s prediction accuracy is higher than other competitive models, and the proposed model is more reasonable for practical cases.
