IMPROVED FRACTIONAL EXPONENTIAL CURVE MODEL FOR NUCLEAR ENERGY GENERATION IN ASIA-PACIFIC REGION

ABSTRACT
To further improve the modelling and forecasting accuracy of the exponential curve model, a new type of exponential curve model is proposed by combining the fractional-order data processing method and a first-order polynomial term. The parameters involved are solved by the piecewise summation technique and the intelligent optimization algorithm. Furthermore, the new model is applied to nuclear energy generation in Asia-Pacific, and the results are compared with the exponential curve model, the modified exponential curve model, and the fractional-order modified exponential curve model. These results indicate that the newly proposed model can obtain more competitive results.
