Research on affine transformation isotonicity of some grey incidence degree models

The purpose of this paper is to study the properties of some grey incidence degree models. This paper creatively proposes the novel definitions of affine transformation isotonicity of grey incidence degree models, and investigates this novel property of some models for grey incidence degree. Finally, the study result implies that the algorithms for general incidence degree, grey pointed incidence degree, grey T-mode incidence degree and incidence degree are satisfy the novel property. This result may further enrich the theoretical system of incidence degree.
