灰色关联分析模型研究进展

systematic carding on the research of grey incidence analysis modelling have been made in this paper. The grey incidence analysis models developed from the models based on incidence coefficient of each points in the sequences in early period to the generalized grey incidence analysis models which based on integral or overall perspective. From the grey incidence analysis models which measuring similarity based on nearness to the models which considering similarity and nearness respectively. The objects of the research advanced from the analysis of relationship among curves to that among curved surfaces, then forward to the analysis of relationship in three-dimensional space and even the relationship among super surfaces in n-dimensional space. The further problems remained to be studied in this field are clarified too. Several research approaches of grey incidence analysis modeling are clearly revealed.
