Grey System Theory Applications
Grey System Theory Applications is a research topic within Management Science and Operations Research. Science Explorer counts 13k research works in it since 1956. 11.9% of them reached the world's top 10% most cited for their field and year.
This cluster of papers focuses on the application of Grey System Theory in forecasting various aspects related to energy consumption, CO2 emissions, and renewable energy. The papers explore the use of time series prediction models, nonlinear grey models, and multivariable grey models to forecast electricity demand, renewable energy consumption, and CO2 emissions. Additionally, the cluster discusses the optimization and application of fractional grey models for accurate forecasting.
