Forecasting the multifactorial interval grey number sequences using grey relational model and GM (1, N) model based on effective information transformation
In the context of data eruption, the data often shows a short-term pattern and changes rapidly which makes it difficult to use a single real value to express. For this kind of small-sample and interval data, how to analyze ...
Quantification of R-fuzzy sets
The main aim of this paper is to connect R-fuzzy sets and type-2 fuzzy sets, so as to provide a practical means to express complex uncertainty without the associated difficulty of a type-2 fuzzy set. The paper puts forward ...
