Grey distance incidence degree and its properties

According to the basic theory of grey system correlation space, a type of new grey incidence degree model is constructed by starting from the perspective of n dimensional linear space. This paper makes a research about some properties of the incidence degree and compares this incidence degree with Deng´s. Results indicate that this incidence degree has the same properties with Deng´s; and it also has some unique advantages. It can reflect the relevance better between system factors in the view of distance space, further enrich and perfect the theoretical system of grey incidence analysis.
