On a sort of new grey incidence models

Based on the definition of absolute degree of grey incidence, which put forward by Professor Liu in 1992, a kind of new models for grey incidence analysis is given in this paper. The interrelations and influence can be measured by the new models with different visual angle of comparability and closeness respectively. And a simplified method to calculate the similitude degree of grey incidence and the close degree of grey incidence are put forward and proved. The properties of the new models grey incidence analysis are studied. Compared with the original definition, the new models for grey incidence analysis with many advantages and are prone to practical applications.
