A Study and improvement on positive and negative relation of Grey Incidence Model
Grey incidence analysis is a multiple factors method that the closeness of the multiple factors relationship is judged based on the similarity level of the geometric patterns of sequence curves. Therefore, slope differences of reference sequences and relevant sequences on every corresponding intervals is used to reflect the closeness of the sequences. The article defined the generalized variation coefficient and put forward a new kind of grey incidence model. This kind of model reflected the positive and negative relation of grey incidence degree to some extent. It is only relate to the geometric shapes of sequences, and has nothing to do with the spatial position of theirs. The method took full advantage of every intervals information and the positive and negative relations. At last, an example was given to prove the rationality and practicability.
