IGOWC-OWGA operators and their applications in interval combination forecasting
Yuan Hong-ju · Journal of Anhui University · 2016
For the shortcoming that C-OWGA operator can only assemble single interval data,this paper proposed a new class of continuous interval data assembled operator. We constructed an IGOWC-OWGA operator by introducing IGOWA operator on the basis of the C-OWGA operator,then we selected vectorial angle cosine as a correlation index and built a new type of continuous interval combination forecasting model.Finally,it is shown that the new method had a significant effect in improving forecasting accuracy by an illustrative example.
