A New Improved Model of the Degree of Grey Slope Incidences Based on the Change Rate of Slope
Based on studying all kinds of main degree of grey incidences models, it founded that there are some flaws in those models. Such as, being 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 practical in both theories and applications.
