Study on one new grey similarity correlation degree model and its applications

Zhang Xiang-Rong and Zhang Qin

Abstract

Grey correlation analysis is not only the important part of grey system theory, but also the cornerstone of grey forecasting, grey policymaking, grey clustering and grey estimating. In this paper, a new computing model of grey similarity correlation degree is constructed based on analyzing grey correlation axioms and the existing computing models of grey correlation degree, then some of its properties is analyzed and proved. The example shows that the models algorithm is simple and has good applicability.
