Abstract
based on studying all kinds of main degree of grey
incidences models, it founded that there are some flaws in those
models. Such as, not satisfied with the property of normality, can
not reflect the relation of positive-negative between sequences,
and so on. In order to solve those problems, a new model for grey
incidence based on the change rate of slope is proposed. This
model calculates the ratio of absolute value of incremental
between a raw data and its next in one sequence, and then,
applies the ratio to calculate the degree of grey incidences
between sequences. The new model is satisfied with not only the
property of normative, but the property of order preservation, at
the same time, the result also can reflect the relation of
positive-negative .The method is proved to be practiced in both
theories and applications.
