The general conformable fractional grey system model and its applications
Wanli Xie, Mingyong Pang, Wen-Ze Wu +2
Grey system theory is an important mathematical tool for describing uncertain information in the real world. It has been used to solve the uncertainty problems specially caused by…
Generalized fractional grey system models: Memory effects perspective
Wanli Xie, Wen-Ze Wu, Chong Liu +1
As an essential characteristics of fractional calculus, the memory effect is served as one of key factors to deal with diverse practical issues, thus has been received extensive at…
Forecasting fuel combustion-related CO emissions by a novel continuous fractional nonlinear grey Bernoulli model with Grey Wolf Optimizer
Wanli Xie, Wen-Ze Wu, Chong Liu +2
Foresight of CO emissions from fuel combustion is essential for policy-makers to identify ready targets for effective reduction plans and further to improve energy policies and…
Continuous grey model with conformable fractional derivative
Wanli Xie, Caixia Liu, Weidong Li +2
The existing fractional grey prediction models mainly use discrete fractional-order difference and accumulation, but in the actual modeling, continuous fractional-order calculus ha…
